A look back at some of the milestones from 2012

2012 was full of major transportation accomplishments.
Happy New Year!!

We think 2013 holds a lot of promise and look forward to the year ahead, but before we get back to blogging about what’s on ADOT’s horizon, we thought we’d take a look back at the year that was…

In 2012, not only did Arizona celebrate its centennial, but the year was full of major accomplishments for the Arizona Department of Transportation – projects progressed, bridges were built, highways were maintained and drivers were warned to ‘Pull Aside, Stay Alive’ during dust storms (who could forget #HaboobHaiku?).

Join us as we reminisce the rest of this week. Today we take a look at some 2012 transportation highlights from around the Valley, tomorrow our focus will shift to the rest of the state and on Friday we’ll feature some MVD and planning achievements.

I-10/Loop 303 Interchange Project 
This year saw substantial progress on what will be a three-year project to construct the multi-level freeway-to-freeway interchange to link I-10 with Loop 303 in Goodyear.

Drivers in the area were able to watch as crews built sections of elevated ramps that will carry traffic to and from Loop 303 north of I-10 by fall 2014. ADOT also opened new I-10 ramps at Sarival Avenue and Citrus Road to replace the now-closed ramps at the Cotton Lane interchange, making room for the larger I-10/Loop 303 interchange to continue.

Crews also worked on significant improvements to stormwater drainage systems and opened a new section of Cotton Lane between McDowell and Thomas roads. The $134 million project also will slightly shift the alignment of I-10 to the north to allow the future connections between the two freeways.

Additional Loop 303 Improvements
The $129 million Loop 303 expansion project south of Grand Avenue (US 60) to Peoria Avenue certainly began to take shape in 2012 as ADOT worked to improve one of the West Valley's key roadways into a six-lane divided freeway between I-10 and US 60.

Traffic was switched this fall onto the future northbound freeway lanes to allow crews to concentrate on the southbound side of the project. ADOT plans to open the southbound lanes in the Grand-to-Peoria area by fall 2013. Other Loop 303 widening work between I-10 and Grand Avenue is scheduled for completion in 2014.

State Route 24 (Gateway Freeway) 
Under the Maricopa Association of Governments’ 20-Year Regional Transportation Plan, work started in 2012 on the one-mile stretch of what will be a brand new freeway – State Route 24 (Gateway Freeway) – between Loop 202 (Santan Freeway) and Ellsworth Road in southeast Mesa. The new freeway segment, scheduled for completion by fall 2013, will provide drivers with improved access to the growing Phoenix-Mesa Gateway Airport. Mesa issued bonds to accelerate the project’s start by several years.

Grand Avenue (US 60) 
ADOT wrapped up a pair of projects in 2012 to add lanes, improve intersections and ease traffic flow along Grand Avenue between 83rd Avenue and Loop 303. The stretch includes a new and durable rubberized asphalt surface.

State Route 143/Sky Harbor Boulevard Interchange 
Crews completed new ramps allowing improved access at Phoenix Sky Harbor International Airport. One new ramp allows drivers for the first time to go directly from eastbound Sky Harbor Boulevard to southbound State Route 143 near the east end of the airport. A new southbound SR 143 ramp provides a direct connection to westbound Sky Harbor Boulevard.

Wow, 2012 was a busy year! Did any of these projects have an impact on your commute? Let us know in the comments and stay tuned – tomorrow we’ll look back on some of the transportation milestones that happened statewide.

I-10 east of Tucson to close overnight March 8 for bridge demolition



If you have travel plans in the southeastern part of our state this Friday night/Saturday morning, you’ll really want to pay attention to this…

I-10 will be closed in both directions from 9 p.m. Friday, March 8 until 6 a.m. Saturday, March 9 for the removal of the old Pantano Union Pacific Railroad Bridge.

That means drivers in the area will need to either alter their travel plans and avoid this segment of I-10 or prepare for a 67-mile detour.

Taking the detour
During the demolition, motorists will be guided by signs through the detour around the I-10 closure, which is between SR 83 east of Tucson (exit 281) and SR 90 west of Benson (exit 302) – see map below. Drivers can expect up to two hours of additional travel time.

  • Eastbound I-10 traffic will detour to SR 83 (Exit 281), travel south to SR 82 in Sonoita, turn left (east) on SR 82 to the SR 90 intersection, turn left (west) onto SR 90 and follow signs to reconnect with I-10 near Benson (Exit 302).
  • Westbound I-10 traffic will detour from the interstate at SR 90 (Exit 302), travel east to the SR 82 intersection, turn right (west) on SR 82 and travel to SR 83 in Sonoita, turn right (north) on SR 83 to reconnect with I-10 at Exit 281.

If you’re traveling that night, you can find a list of 24-hour fuel station locations HERE.

Some background…
Readers of the ADOT Blog may remember that this same segment of I-10 was closed overnight about two years ago for the demolition of the old Marsh Station traffic interchange (see the amazing video HERE and HERE).

That bridge removal back in 2011 was part of the same project that’s necessitating the removal of the Pantano Union Pacific Railroad Bridge this coming Friday.

Both the old Marsh Station interchange bridge and the UPRR bridge were approximately the same height, requiring trucks over 15 feet in height to use State Routes 83, 82 and 90 as a 67-mile detour off I-10.

A new Marsh Station traffic interchange opened on Dec. 20, 2010. It was constructed to accommodate today’s taller trucks with a clearance of 16 feet and five inches, however the taller trucks haven’t been able to use the segment of I-10, yet...

When the old UPRR bridge is removed, more trucks will be able to pass through the new traffic interchange and will no longer need to use the costly and time consuming detour. Most of the taller trucks that once needed to detour from I-10 will no longer use SR 83, freeing the scenic highway and the small town of Sonoita of congested truck traffic.

Reconstruction of I-17 traffic interchange at Munds Park nears completion

A view of the project on I-17 at Munds Park.
Winter is coming…

Maybe that’s hard to believe if you live in hotter regions of the state, but residents up north already are starting to experience chillier temperatures.

And – as ardent readers of this blog may know – when freezing, cold weather hits, many of ADOT’s northern Arizona projects go on hiatus

Before that happens we wanted to check in on a project about 20 miles south of Flagstaff.

A little bit of background…
ADOT began construction in spring 2011 to reconstruct the bridges and ramps on I-17 at Munds Park. The first phase of the project, which included the reconstruction of the northbound I-17 bridge and ramps, was completed last year.

The second phase of the project started in March 2012 and now is winding down. This phase includes reconstructing the southbound I-17 bridge and ramps, as well as the realignment of Pinewood Boulevard (the street that runs underneath the I-17 bridges). 

This project gives motorists two new bridges each measuring 100-feet long – they were just 25 feet to begin with. The increased length accommodates a wider Pinewood Blvd and a 10’ sidewalk for pedestrian traffic. The new bridges are wider, too. This will help to accommodate traffic and an eventual third lane (in each direction) planned for I-17.

The upgrade is necessary to handle increased traffic levels – the old bridges were built in 1958 and back then there wasn’t much development (and not a lot of traffic) in Munds Park.

Where we are now
Both new bridges are built and the old bridges are gone!

Northbound and southbound traffic had been sharing the northbound lanes for this phase of the project, but just last week southbound traffic was rerouted back to the southbound lanes (northbound traffic stays on the northbound lanes).

The new bridges are adorned with designs
There is still some work to be done, so traffic is restricted to one lane in both directions during the weekdays. The restrictions are generally lifted during weekends allowing traffic to flow in two lanes each direction.

A few of the things crews currently are working on includes, guardrail, lighting, rock fall protection and finishing up the improvements to Pinewood Boulevard.

Work will continue (depending on the weather) through the middle of November … that’s when crews will shut down for the winter.

The project will be essentially finished at that time, but crews will return in summer 2013 to apply the top layer of asphalt pavement when weather conditions are ideal for that work.

Resident Engineer Adam Umholtz reminds drivers to be aware in the work zone as crews are finishing the project, especially as winter storms start rolling in.

“Be patient and observe the posted speed limits and traffic controls through the project," he said. "Winter is coming our way and we are out there trying to make it a safe road for the whole winter.”

More information can be found on the project webpage.

Crews wrap up work on I-17 traffic interchange at Munds Park


The Munds Park traffic interchange on I-17 has come a long way since we first checked in on construction...

That was back in May 2011 when work on the project had just gotten started. Since then, crews have reconstructed bridges and made other improvements to the site located about 20 miles south of Flagstaff.

We’ve been interested to watch the project progress and we think the video above gives a good look at how it has taken shape. But, as we viewed the video, we also started to notice how well it showcases many of the transportation concepts we’ve covered before here on the blog.

That’s when we had the idea to take note of all the previous blog topics that were being mentioned or shown. We thought it’d be fun to see if you can spot all these subjects as you’re watching the video:
So, did we get them all? Did you notice any others? Let us know in the comments!

MVD provides services, assists veterans at 2013 Arizona StandDown

MVD employees help veterans get driver licenses and ID cards
(photo top left). MVD employees bag up sandwiches and other
food items – even dog treats for pets belonging to veterans
(photo bottom right). The ceremonial cutting of red tape kicked
off the 2013 Arizona StandDown (photo bottom left).
The 2013 Arizona StandDown began with the ceremonial cutting of red tape – a fitting kickoff to the annual outreach event aimed at connecting homeless and at-risk veterans with needed resources.

Held March 8-10 at the Veteran’s Memorial Coliseum in Phoenix, this year’s StandDown included more than 92 housing, healthcare and support service providers.

All were on hand to cut through that red tape and assist the state’s homeless veteran population.

As in years past, MVD was there to help the veterans obtain driver licenses or state identification cards – vital when job searching or applying for programs. 

“Having that credential really gives you an identity,” said MVD Director Stacey Stanton. “Hopefully that credential will give them access to other services they need.”

MVD Regional Manager Dave Jackson agrees…

A veteran himself, Jackson serves on the Arizona StandDown executive committee and says getting an identification card or license is often the first step to a better path.

“It’s one of the major things they need to have in order to get jobs, services, anything,” he said.

Just like last year, dozens of MVD employees were on site. They brought along 12 complete work stations, which were set up like an MVD office. Veterans could conduct transactions for driver license applications, renewals, written examinations and the road skills test (Courtesy Chevrolet provided vehicles to be used for those who did not have one of their own).

Besides the typical MVD services, the veterans were also treated to homemade sandwiches, cupcakes and other edible treats – all courtesy of MVD employees.

Jackson explained that being at the StandDown and providing a service means so much to the MVD employees.

“It’s just a big deal for all of us,” he said.

Reducing motorcycle-crash deaths a statewide priority

Click on photo for larger view.
Motorcycle-crash deaths in Arizona rose 59 percent between 2010 and 2011, an alarming statistic ADOT Director John Halikowski spoke of during a safety event held yesterday in Gilbert.

Halikowski was joined by Governor’s Office of Highway Safety Director Alberto Gutier and both stressed the importance of rider training while talking about statewide efforts to reduce fatal motorcycle-related crashes...

“As our economy continues to recover, people are driving more, and that's a factor when it comes to increasing crashes and fatalities, especially motorcycle-related deaths,” said Halikowski. “We'd encourage any riders to take safety courses approved by the Motorcycle Safety Foundation.”

Finding effective strategies for reducing crashes, fatalities and serious injuries
Governor Jan Brewer has directed ADOT and the highway safety office to develop a range of strategies for reducing motor vehicle crashes and fatalities in Arizona.

“Governor Brewer has made this one of the state's goals and driver education will play a big role in making it happen,” said Gutier. “Motorcycle rider training is an important example of that.”

The state’s public safety agencies will work this year with other safety organizations and stakeholders to update the Arizona Strategic Highway Safety Plan.

“We're determined to turn any trend toward increased deaths and injuries around,” said Halikowski. “In addition to motorcycle training, it will be important for all of us as drivers to be vigilant in paying extra attention to motorcycle riders, bicyclists and pedestrians.”

Director Gutier said motorcycle and general passenger vehicle safety starts with reducing the leading causes of traffic crash deaths.

"We all benefit when we obey speed limits, don't drive while impaired, avoid distractions and use proper restraints."

The TEAM Arizona motorcycle-training center in Gilbert, which hosted Wednesday's event, marked the training of its 100,000th rider over more than two decades. That rider was presented with a new Kawasaki motorcycle.

PARA funds assist rural areas with transportation planning

Readers of this blog know ADOT is the agency that often allocates federal grant funds to different entities from across the state (schools, communities, etc.) for transportation-related projects…

But, did you know there’s a program sponsored by ADOT that provides federal funds for the purpose of conducting transportation planning studies?

The program is known as PARA (Planning Assistance for Rural Areas) and it provides these funds to non-metropolitan communities.

More on PARA
PARA funds can’t be used for the design or construction of transportation projects, but the money can be used to plan for and address a range of issues related to roadway and non-motorized transportation modes. Public transportation services can be studied with PARA funds, too.

Some examples of what issues may be addressed by PARA program funding:
  • Roadway and transit operations/facilities planning 
  • Development or update of a municipality’s circulation element in its general plan 
  • Bicycle and pedestrian planning 
  • Trails planning 

Sierra Vista study 
ADOT administered PARA program funding to Sierra Vista so the city can develop a Travel Reduction Plan that will ultimately identify options to improve traffic flow by reducing the number of motorists who drive alone to work or school.

So far, the city has completed an efficiency study that surveyed workers at Sierra Vista’s largest workplaces to better understand how people commute and what types of programs would encourage them to make fewer single-occupancy vehicle trips. The study found that more than 90 percent of workers in Sierra Vista currently drive to and from work and school alone.

Most recently, ADOT and the city launched an online survey to lean about the travel habits of Sierra Vista residents and to understand what alternative options might reduce single-occupancy vehicle trips.

Findings from the studies and surveys will be used by Sierra Vista to develop the final Travel Reduction Plan.

SR 24 construction requires Santan traffic switch this weekend

SR 24 project area.
It’s been a while since we checked in with the SR 24 out in the East Valley.

You remember this project, right?

Also known as the Gateway Freeway, SR 24 is designed to span one mile between Loop 202 (Santan Freeway) and Ellsworth Road. When construction is finished in fall 2013, this new freeway will feature a freeway to freeway interchange, complete with elevated ramps connecting to and from Loop 202 near Hawes Road.

Crews have been at work for the past six months and now we’re headed toward a project milestone…

A traffic switch is coming
This weekend, Loop 202 (Santan) will be closed between Power and Elliot roads so crews can install temporary concrete barrier and restripe the road – the closure is expected to last through 5 p.m. Sunday, Sept. 30.

The work is necessary to prep the roadway for an upcoming long-term detour that will move westbound traffic onto the eastbound lanes of Loop 202 between Warner and Hawes roads.

After this Sunday, both east and westbound drivers will be using two lanes each on the eastbound side of Loop 202. The traffic switch will allow crews to continue constructing the ramps and bridges that will connect Loop 202 to the new one-mile stretch of SR 24.

This traffic switch is the first phase of ramp and bridge construction. In phase two, eastbound traffic will be detoured onto the westbound lanes of Loop 202 in Mesa. These detours will be in place until late summer 2013.

When work is finished drivers can look forward to…
  • A new freeway to freeway interchange, a widened Loop 202 and the first mile of the new SR 24 ending at Ellsworth Road. 
  • Enhanced access from southeast Maricopa County to northeast Pinal County. 
  • Additional routes into and out of Phoenix-Mesa Gateway Airport and its surrounding businesses and schools.

ADOT crews get ready for a snowy winter


ADOT snowplow drivers and support staff already are preparing for the icy, cold months ahead…

And, yes, ADOT has snowplow drivers – the state isn’t all desert! Arizona winters always bring plenty of storms to keep our crews busy … remember this doozy from March

The ultimate goal for our crews is to stay safe on the job, while keeping the roads clear and safe for drivers – that means continued training is essential for the state’s 450-plus snowplow drivers.

This year, ADOT leadership put together a winter readiness training workshop for all employees involved in winter storm maintenance. The event provided a comprehensive look at everything and anything related to winter storm maintenance and safety.

State Maintenance Engineer Lonnie Hendrix explains in the video above why this training is so vital.

“To make sure we’re as prepared as possible to make the roads and highways in the state safe and open during winter storms,” he said. “As a winter storm passes through the state we typically mobilize half the value of our entire equipment fleet. We’ll mobilize half of our entire highway maintenance work force. We’ll spend millions of dollars on chemicals. So these events are very expensive. They’re very important to us and it’s important that we do a good job.”

For more on how ADOT crews handle winter weather, check out these blog posts.

Transportation Defined: Recessed Pavement Markers

Recessed pavement markers
are used in colder climates.
Most drivers are probably familiar with pavement markers…

They’re the reflective objects typically placed on the road in between pavement stripes – you’ll often see them along the solid pavement lines, too, or on exit/entrance ramps. Basically, they’re used to give drivers a better guide at night.

Nothing new there, but did you know that the markers can vary depending on their location?

That’s right … if you travel up north you may notice that the pavement markers are recessed, rather than raised as they are in most other parts of the state.

Any ideas why that is?

We asked ADOT Project Supervisor Rick Schilke for an explanation and he says it has to do with snowplows.

A diagram of recessed
pavement markers.
“Up here, we sink the pavement markers down for the plows, otherwise they’d just pop right off,” he said.

Makes sense to us!

Installing recessed pavement markers requires a little more work than the raised markers. Schilke says crews must grind a groove into the road that tapers down at an angle allowing for reflection. The marker is then put into place with an epoxy.

One more thing to note: In areas where snow is expected in the colder seasons, ADOT crews actually recess stripes, too. (We’re not talking about painted stripes, ADOT uses striping “tape” that’s more durable and reflective than paint.) The striping tape is recessed so that it won’t be displaced by snowplows.

Now that we've got your attention...

By Nicole Sherbert
ADOT Assistant Communication Director

It would be an understatement to say that we’ve experienced a bit of a surge in our social media audience of late.

Those of us who have spent the last few years working to build ADOT’s online network would love to believe that our spontaneous increase in viewers, followers and readers is due solely to our engaging content and commitment to transparency…

Or, it might have something to do with the photo to the right.

If you’re reading today’s blog post, chances are you are at least familiar with the context of this photo, but just in case, a quick recap:

On Feb. 20, a landslide ripped through the mountainside at US 89 in northern Arizona about 25 miles south of Page forcing ADOT to immediately and indefinitely close the highway – a major travel route in an area where – to use engineer speak – there is little redundancy of travel routes.

To help spread the word of the road closure and evolving situation, we immediately took to our social media outlets, starting with tweeting and posting to Facebook the photo above. Within two hours, that single photo had been shared and retweeted nearly 1,000 times. Within 24 hours, the shares of that and related photos climbed to more than 6,000 – leading to a Facebook estimated one-week reach of nearly 400,000 users.

Within 24 hours, a YouTube video explaining the situation had been viewed 5,000+ times. To date, it and two subsequent videos have been viewed close to 50,000 times.

But why does this matter? Sure, they were dramatic photos, but outside of the wow factor, what’s the point?

The simple answer is to rapidly spread important information.

While US 89 is a rural road in a relatively remote part of the state, an average of 5,000 people a day travel that stretch of highway and traffic increases dramatically in the coming weeks when folks around the world head to Lake Powell and nearby national parks and monuments.

So how do we reach people to get the word out that motorists should expect a detour but that Page and the surrounding areas are still open for business? By reaching out to a network broader than just our own.

And this is when social media is at its best…when users serve as real-time information sources to reach an extended, networked audience.

But, what now? 
If you are one of the 1,600 people who “liked” us on Facebook the week of Feb. 20, I’m guessing that leading up to seeing those photos you may not have even known ADOT had a Facebook page, more or less a blog and YouTube channel. And while we can’t tell you how much we wish it was under different circumstances, we’re glad you found us and hope you stay engaged.

We’ll continue to provide updates about US 89, but we have a lot of really important information to share and we hope you’ll continue to help us spread the word. Here are three great ways to start:
  1. Yesterday, we blogged about ADOT’s tentative Five-Year Construction Program and asked you to provide comment. And while it lacks the drama of a quarter-mile landslide, it is your opportunity to have your voice heard about the future of your Arizona highway system. 
  2. Do you, or anyone you know, travel in southern Arizona? Then you might want to share this blog post from Monday explaining that a bridge removal in southern Arizona will necessitate the closure of I-10 south of Tucson for about nine hours tonight. (And the only way around is a 67-mile detour.) 
  3. On Monday we will be launching a new public safety campaign aimed at protecting the lives of everyone who drives or works on Arizona roadways. And while we’re still putting some final touches on the website, we thought we’d give you a sneak peek just for being a loyal blog follower. 
If you’re new to our social media network, we hope you’ll stick around, ask us questions and continue to share our information. And for those who have been around for a while and helped us build our social media foundation, thank you.

Public input helps shape San Pedro River Bridge replacement project



Public involvement truly helps shape ADOT projects … just ask residents living near the San Pedro River Bridge.

Their local bridge sits on SR 90 and is slated for replacement – construction has already begun, in fact.

But, way before work got started earlier this week those residents took part in several ADOT public meetings where they were given a couple of different construction schedule alternatives.  

One option called for a full closure of SR 90 at the San Pedro River…

That choice would have allowed the bridge replacement to wrap up in a six-month time frame, but it would have meant very lengthy detours for residents. The option was eliminated after comments from residents indicated a preference for a longer project schedule that would be able to keep SR 90 open through the duration.

18-month construction schedule – no extended full closure
“We’ll have a six-month construction period, six months of shut down for the summer migratory bird season in the San Pedro riparian wilderness area, which is where the bridge project is, and then six more months to finish the bridge,” says ADOT Senior Community Relations Officer C.T. Revere.

What else do drivers need to know?
This bridge, constructed in 1955, will be replaced by a new structure featuring wider traffic lanes and shoulders that meet current standards and provide adequate space for vehicles – including emergency responders, bicycles and pedestrians.

Construction on the $7 million bridge replacement project started Oct. 1 and once work is complete (by spring 2014), drivers can expect:
  • A new 44-foot wide bridge that replaces the existing 26-foot wide bridge.
  •  Two 12-foot traffic lanes and 10-foot shoulders in both directions.
  • Improved guardrails, and roadway and bridge approaches.
  • A new bridge that’s six feet higher than the existing structure (this is to comply with 100-year floodplain requirements.

Drivers also should take note of this project’s impact on traffic…
  • A temporary traffic signal will guide alternating traffic through a single shared lane during construction. Wait times are expected to be 5 to 8 minutes, with delays of up to 15 minutes possible. Motorists are advised to plan ahead and allow extra travel time.
  • Some overnight closures of SR 90 will be required for the safety of the public. Those scheduled closures will be announced in advance
  • ADOT intends to have one lane open in each direction with no traffic signal during the season that construction work is shut down.

More information on this project – including maps, traffic alerts and construction fact sheets – can be found on the SR 90 San PedroBridge replacement project webpage.

ADOT Communications Team earns honors at TransComm

The "Building a Freeway – Caissons" video earned one
of three awards presented to ADOT at the 2012
TransComm conference.
We don’t normally talk about ourselves – the ADOT Communications Team – on this blog.

Instead, we’re more focused on sharing stories and highlighting the accomplishments of the ADOT engineers, planners, maintenance crews and all the other (numerous) departments who work everyday to plan, build and maintain this state’s highway system.

We like it that way … but today we’re so excited that we’ve just got to tell you about a few honors our team received yesterday.

TransComm
Unless you run in the same circles as state transportation communicators, you probably don’t know about TransComm … so let us explain.

TransComm is the annual meeting for the American Association of State Highway and Transportation Officials’ (AASHTO) Subcommittee on Transportation Communications. This is a conference that brings transportation communication professionals together to learn and exchange ideas.

It’s also the place where state DOTs are recognized for the work of their communications and public relations teams through the TransComm Skills Contest.

The contest is conducted annually by the AASHTO Subcommittee on Transportation Communications and is the premier competition in the transportation industry. So, you can imagine how thrilled we were to get the word this morning that ADOT’s Communications Team earned three awards!

The honors were announced last night at the conclusion of TransComm and ADOT Communications were on hand to receive recognition for best interactive presentation, best external video and best blog.

Interactive presentation: This is a presentation that was developed to provide basic background information on transportation to the public (a portion of the presentation – a video – can be seen HERE). It utilizes video and graphic design to effectively communicate with audiences the particulars of transportation funding in Arizona. It has been successfully delivered in a variety of venues, including several town and city council meetings.

External Video: You probably know about this one! Having received more than 4,000 views on YouTube, it’s one of our most popular videos. Of course, we’re talking about “Building a Freeway – Caissons.” The video was recognized for taking a highly technical engineering/construction topic and presenting it in an entertaining and interesting manner. We still love re-watching this fast-paced, stylish (and educational) video!

Blog: If you’re reading this, then you’re already familiar with the ADOT Blog! We launched it a little more than a year ago to connect with the public and give people a better understanding of how their transportation system is planned, built, maintained and financed. It’s proven to be a valuable tool allowing us to shine light on not just what ADOT does, but how and why we do it. When the awards were handed out last night, it was noted that the ADOT Blog does a good job covering a breadth of transportation topics, which is something we’re proud of (but, we know there's plenty more to write about!).

OK … tomorrow we’ll go back to blogging about the rest of ADOT (we have a really cool project video coming up!), but thanks for indulging us (and letting us toot our own horn!). And, also thank you for reading, watching and interacting with us – you’re a great audience!

One last thing … 
At the end of this year’s TransComm it was announced that Arizona would be the host state for the 2014 conference – a tremendous honor. We’re looking forward to hosting our colleagues in two years!

Buckled pavement closes US 89 south of Page



By now, many of you have probably already seen photos of US 89

A 150-foot section of the road “buckled” yesterday morning (Feb. 20) in an area about 25 miles south of Page – the cause of the highway damage may have been a geologic event.

While it will take a while to assess what happened and figure out how to fix it, we can tell you now that ADOT is currently conducting a geotechnical analysis that will determine the scope of highway repairs to be made.

Once a determination is made, ADOT will utilize emergency contract procedures to restore the highway.

For the foreseeable future, the section of US 89 will remain closed in both directions between US 89A, which takes motorists west toward Jacob Lake, and the US 89 junction with SR 98 in Page.

US 89 buckled pavement closure.
Motorists will use an alternate route to and from Page while this section of US 89 remains closed. That alternate route detours motorists on US 160 to SR 98, which is about 45 miles longer than the direct route (see map for detour).

Moving forward
ADOT funds will be used to cover the repair costs. At a future date, ADOT will seek reimbursement for the repair costs through the Federal Highway Administration Emergency Repair Program. The reimbursement process does not hinder action to repair the highway.

Keep informed
If you would like to receive email updates on US 89, you can subscribe online.

We will continue to provide updates as information is available here on the blog, on Facebook and on Twitter. As always, drivers can get details on highway and traffic conditions statewide at www.az511.gov.

Building a freeway: box girders


As you can see in the video above, girders are the concrete and steel beams that enable the bridge to support the roadway and the vehicles on top of it.

They’re vital to the design of a bridge, but not all girders are the same…

Just like each bridge in Arizona is individually designed to hold up in the conditions unique to its surroundings, girders differ in size, shape and type, depending on the situation in which they’re being used.

This is a topic that can get complex real fast, so we’re going to keep it simple today by just focusing on two types of concrete box girders: prestressed concrete box girders (these are featured in the above video) and post tension concrete box girders.

But first, we’re going to need to look inside the girder itself…

The girders we’re referring to are made up of very strong steel strands or rods that are surrounded by concrete. The difference between the two types of girders hinges on when the tensioning (or stretching) of the steel takes place – it’s either before or after the concrete is poured.

Tensioning, by the way, is done to give the concrete some additional strength. This explanation from the ADOT Construction Manual might help better explain the need for tensioning/stretching:

Concrete is strong in compression and weak in tension. Reinforcing steel is generally used to carry the tensile loads placed on a concrete structure … Reinforcing steel is used to help concrete carry compressive loads and shear stresses that develop when loads move through a structure.

If a girder is prestressed or pretensioned, the steel strands are stretched to a predetermined stress and then concrete is poured around the strands.

“Once the concrete has hardened and gained sufficient strength, the ends of the strands are cut. The strands inside the concrete try to relax and shorten. However, there is now concrete bonded to the strands. As the strand shorten, they push the concrete together and induces a compressive stress into the concrete,” according to the ADOT Construction Manual.

More from the manual regarding post-tensioning…

Post-tensioning involves running steel ducts through the concrete (girders). Special anchors are placed at each end of the (girder). Then concrete is poured around the ducts and the anchors. Steel strands are run through the ducts. Once the concrete is strong enough, the strands are pulled at one end while anchored at the other.

Pulling (or jacking) of the strands causes the ends of the concrete (girder) to push toward each other. This induces compressive stresses along the entire length of the concrete member. After jacking, grout is injected into the ducts then concrete is poured around the ends of the anchors. Once the grout gains strength, the strand is now bonded to the concrete member in a way similar to pretensioning.

When to use prestressed vs. post-tensioned girders
State Bridge Engineer Jean Nehme says that using prestressed box girders is sometimes more convenient because they’re constructed off the project site.

“Because you build them off-site, you cut down on the time of construction,” said Nehme, adding that using prestressed girders can cut down on the need for traffic closures.

But, whether the girder is prestressed or post-tensioned, Nehme says by tensioning the reinforcing in the concrete, engineers can design stronger bridges that span longer distances.

“It provides better durability in the long term,” he said.

Loop 303 closure scheduled this weekend as project reaches a major milestone

During the closure, drivers can use
Reems Road from Grand Avenue
 to Glendale Avenue
. Officers will
be on site to help guide traffic
through any four-way stops along
Reems Road. Most east-west streets
in the area will remain open.
Those of you who drive Loop 303 in the Surprise area are in for a big switch…

Starting next week you’ll be traveling on the newly-constructed northbound side of the freeway between Peoria Avenue and Mountain View Boulevard. The traffic switch is necessary so crews can start building the future southbound lanes as part of the ongoing project that’s transforming Loop 303 from a two-lane roadway into a modern urban freeway. This is a big milestone for the project and marks the completion of Phase I and a move into Phase II.

In order to switch traffic from one side of the freeway over to the newly-completed portion, ADOT is scheduled to close Loop 303 between Grand and Glendale avenues from 10 p.m. tonight (Oct. 26) to 6 p.m. Sunday (Oct. 28). Traffic will be detoured along Reems Road while Loop 303 is closed. Most east-west streets in the area will remain open.

The closure will give crews time to finalize paving and striping as well as set up barriers, signals and signage – all necessary for the new traffic configuration.

After the weekend closure…
When the switch is complete, Loop 303 traffic will use one lane in each direction on the new northbound pavement that starts just north of Peoria Avenue and the off- and on-ramps at the interchanges at Cactus, Waddell, Greenway and Bell roads. Temporary traffic signals will allow the two-way traffic to move through those intersections.

The $128.7 million project to upgrade Loop 303 between Peoria Avenue and Mountain View Boulevard, south of Grand Avenue, is scheduled for completion in fall 2013. Check out yesterday’s blog post for a look at the progress so far …

This isn’t the only project under way on the Loop 303. The entire freeway (which stretches from I-10 in Goodyear to I-17 in Phoenix) is getting updated in several areas. For a detailed overview of all those projects, visit azdot.gov/Loop303.

ADOT enhances online camera images as part of operations center upgrade

A look at one of the camera images you'll see on az511.gov.
Did you know you can check your commute before you head out on the road?

All you have to do is visit az511.gov and take a look at the view from our freeway cameras

That view can be useful, because knowing what to expect on the road ahead helps drivers make informed decisions concerning their route.

Wait, that sounds really familiar. Didn’t we use that line a couple weeks ago when we blogged about freeway travel times? At any rate, it works here too, so we’re leaving it!

Images now refresh more frequently
The recent high-tech makeover to ADOT’s Traffic Operations Center definitely wasn’t just superficial. The overhaul also brought in new equipment that converts the analog signal from the cameras into a digital one that can be maintained at the TOC in a digital format.

While that may not sound like much, the new complex processor that does the converting gives TOC employees more tools and better options for monitoring and traffic control. The change also permits the images on az511.gov to be updated more frequently.

Until just recently, images would refresh after about five minutes ... now they’re updated every 10 seconds, giving visitors to the site a better idea of how traffic is moving along (go ahead and check it out!).

What the cameras are used for
Traffic cameras are used to quickly identify incidents so traffic can be redirected, provide first responders with fast, accurate information, and allow commuters to make more informed decisions on their routes. The cameras are not used for enforcement of traffic laws, and the images are not recorded by ADOT.

More cameras
Not all sections of freeway have cameras, but according to ADOT Server Team Manager Darrell Bingham, additional cameras are added as new freeway projects are built. He explained that new cameras will soon be up and running on the Loop 202 (Red Mountain Freeway) between Loop 101 and Gilbert Road.

“Now, the system will help give users a much better, accurate story,” Bingham said of all the improvements.
