PHOENIX — The Arizona Department of Transportation continues to make considerable progress on an improvement project to widen and upgrade a five-mile segment of US 93 between State Route 71 and State Route 89, just north of Wickenburg.

On Thursday, Oct. 1, crews are scheduled to switch both directions of traffic to the newly constructed southbound lanes. As crews make preparations for the planned traffic switch, motorists may be stopped intermittently for up to 15 minutes at a time between 6 a.m. and 6 p.m. on Oct. 1.

While one travel lane will remain open in both directions, motorists should continue to be prepared to allow 10 to 15 minutes extra travel time through this segment (mileposts 185-190).

Once the traffic switch is complete, ADOT will begin work to repave and restripe the existing northbound lanes.

ADOT began this expansion project in February to widen US 93 from two lanes to a modern, four-lane divided highway. The $12.5 million project is expected to be completed in November.

Once completed, ADOT will move one step closer to the agency’s ultimate goal of transforming the entire 200-mile stretch from Wickenburg to the Hoover Dam bypass bridge into a modern, four-lane divided highway.

Since 1998, ADOT has invested more than $350 million in projects to upgrade the US 93 corridor, which stretches from Kingman to the Nevada state line and Wickenburg to Interstate 40 (a 23-mile segment of I-40 east of Kingman connects the north and south sections of US 93).

Currently, all but 46 miles of the 200-mile drive (more than 75 percent) from Wickenburg to the Nevada state line has been upgraded to a four-lane divided highway in an effort to improve traffic flow, support the movement of freight and enhance safety through this heavily traveled area.

PHOENIX — The Arizona Department of Transportation, which has been nationally recognized for its creative and innovative solutions to promote safe travel while protecting wildlife and connecting ecosystems, received another accolade for its leadership in developing wildlife crossing structures in Arizona.

The U.S. Department of Transportation’s Federal Highway Administration recently awarded ADOT and its partner Animal Road Crossing Solutions this year’s Environmental Excellence Award for Excellence in Environmental Leadership.

Arizona has long been considered a leader in wildlife connectivity issues. ADOT and multiple partner agencies, including the Arizona Game and Fish Department, collaborated to construct wildlife underpasses and elk crossings along State Route 260 east of Payson and desert bighorn sheep overpasses near historic Hoover Dam on US 93.

“ADOT has a long record of innovative and successful wildlife accommodations as part of construction projects,” said ADOT Director John Halikowski. “While ADOT is not a wildlife-management agency, we are a transportation safety agency and we partner with other agencies, such as the Arizona Game and Fish Department, in an effort to preserve and protect wildlife, while reducing vehicle-wildlife collisions.”

According to data collected by the Arizona Game and Fish Department, more than 15,000 crossings by 16 species of animals were recorded at six underpasses along SR 260 in Arizona over a seven-year period. In addition, more than 4,300 desert bighorn sheep crossed three overpasses on US 93 in Arizona in a two-year span.

In addition to preserving wildlife, these specialized crossings protect drivers from crashes with some of the state’s big game.

A fencing project linking three existing crossing structures on SR 260 reduced elk-vehicle collisions by 98 percent over a six-year span.

Wildlife crossing structures and fencing can greatly lessen the impact of traffic because, together, they provide safe linkages across highways, helping ensure stable local and regional wildlife populations.

Selected by an independent panel, the Environmental Excellence Award is the Federal Highway Administration’s biennial recognition of innovative efforts to preserve the environment while enhancing America’s highways.

“Building a 21st-century transportation system that is cost-efficient and protects the environment requires creativity and innovation,” said U.S. Transportation Secretary Anthony Foxx. “These awards demonstrate FHWA’s support of projects that approach current and future transportation challenges with new solutions.”

June 29, 2015

PHOENIX — For the past two decades, the Arizona Department of Transportation has made the US 93 corridor a priority, by methodically turning what was once a two-lane rural roadway into a modern four-lane divided highway along the primary travel route for Phoenix motorists headed to Las Vegas and a vital corridor for trade and commerce.

This past weekend, ADOT completed another widened section of US 93, approximately 20 miles north of Wikieup and moved one step closer to the agency’s ultimate goal of transforming the entire 200-mile stretch from Wickenburg to the Hoover Dam bypass bridge into a modern, four-lane divided highway.

The completed $20 million project widened the three-mile-long Antelope Wash segment of US 93 (mileposts 101-104), which included building two new southbound lanes and reconstructing the two northbound lanes to tie into the new roadway configuration.

This was one of two US 93 widening projects ADOT has been working on this year. In February, ADOT launched another expansion project along US 93 between state routes 71 and 89 (mileposts 185-190), just north of Wickenburg. The $12.5 million project will include converting the roadway from two lanes to four lanes and is expected to be completed in 2016.

Since 1998, ADOT has invested more than $350 million in projects to upgrade the US 93 corridor, which stretches from Kingman to the Nevada state line and Wickenburg to Interstate 40 (a 23-mile segment of I-40 east of Kingman connects the north and south sections of US 93).

Currently, all but 46 miles of the 200-mile drive (more than 75 percent) from Wickenburg to the Nevada state line has been upgraded to a four-lane divided highway in an effort to improve traffic flow, support the movement of freight and enhance safety through this heavily traveled area. The entire northern segment of US 93 from Kingman to the Nevada state line (mileposts 1-68) is now a four-lane divided highway following the completion of a $71 million project in 2010.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.

PHOENIX — Motorists traveling on US 93 between Phoenix and Las Vegas beginning Tuesday, April 7 through Thursday, April 9 should be prepared for possible delays and allow for extra travel time during daylight hours as crews continue to make progress on a $20 million widening project (mileposts 101-104), approximately 20 miles north of Wikieup, according to the Arizona Department of Transportation.

Intermittent closures in both directions up to 15 minutes will be necessary from 7 a.m. to 4 p.m. from April 7-9 to allow crews to use large cranes to deliver and set up several bridge girders as part of the improvement project. Flagging stations and law enforcement will be located within the work zone.

Earlier this year, traffic was switched to the new southbound lanes and reconstruction continues on the future northbound lanes, located adjacent to the existing US 93 alignment. The three-mile-long Antelope Wash segment includes building two new lanes to provide motorists with a four-lane divided highway, and is expected to be completed this summer.

ADOT advises drivers to proceed through the work zone with caution, slow down, and be alert for construction equipment and personnel. The current construction schedule is Monday through Thursday, 6 a.m. to 5 p.m. Additional delays may occur on weekends due to heavier traffic volumes and special events.

 ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.

February 19, 2015

PHOENIX — The Arizona Department of Transportation launched a new project this week to widen US 93, the primary travel route for Phoenix drivers headed to Las Vegas, and efforts continue on another ongoing widening project to further a decades-long commitment to convert the rural two-lane roadway to a modern, four-lane divided highway in northwest Arizona.

Just north of Wickenburg, ADOT started this week on the expansion of US 93 between State Route 71 and State Route 89 (mileposts 185-190). The $12.5 million project, reconstructing the highway into four lanes, is expected to be completed in 2016.

This project will be funded through the Federal Highway Administration’s Highway Safety Improvement Program.

Along this section of highway, ADOT previously installed a centerline rumble strip, which is a pattern of small cuts in the pavement, in an effort to alert drivers whose vehicles cross the centerline of the two-lane, two-way roadway. Signs were also added to remind drivers that US 93 has two-way traffic and ADOT made it a requirement that drivers use their headlights during daylight hours.

“Safety has been the drive force behind our series of projects to convert US 93 into a divided four-lane highway,” said ADOT State Engineer Dallas Hammit. “ADOT’s long-term goal is to have a modern, four-lane divided highway between Phoenix and Las Vegas and we’ll continue to get closer to that goal as funding becomes available.”

Approximately 80 miles north of the project near Wickenburg, ADOT is continuing work on widening the Antelope Wash segment of US 93 (mileposts 101-104), roughly 20 miles north of Wikieup.

The $20 million improvement project began last summer and crews are currently reconstructing the future northbound lanes of US 93, which are adjacent to the existing US 93 alignment. The widening project, which is nearly 70 percent completed, is slated to be finished this summer.

ADOT urges drivers to proceed through the work zones with caution, slow down, and be alert for construction equipment and personnel.

Since 1998, ADOT has invested approximately $350 million in projects to upgrade the US 93 corridor, which stretches from Kingman to the Nevada state line and Wickenburg to Interstate 40 (a 23-mile segment of I-40 east of Kingman connects the north and south sections of US 93).

Currently, all but 49 miles of the 200-mile drive (more than 75 percent) from Wickenburg to the Nevada state line has been upgraded to a four-lane divided highway in an effort to improve traffic flow, support the movement of freight and enhance safety through this heavily-traveled area. The entire northern segment of US 93 from Kingman to the Nevada state line (mileposts 1-68) is now a four-lane divided highway following the completion of a $71 million project in 2010.

When the SR 71 to SR 89 and Antelope Wash sections are completed, ADOT will have widened an additional eight miles of the 109-mile stretch of US 93 from Wickenburg to I-40.

Ultimately, US 93 could become part of the proposed Interstate 11 corridor that, once fully constructed, would connect Nogales and Las Vegas, extending north through Nevada, potentially reaching as far as Canada.

Last October, ADOT and the Nevada Department of Transportation completed the I-11 and Intermountain West Corridor Concept Report, the final element in the initial two-year feasibility study, this document can be found at www.i11study.com.

“US 93 has been designated as a potential alignment for the proposed Interstate 11 corridor,” said ADOT Director John Halikowski. “With the continued growth in the southwest, it’s essential that we have the transportation infrastructure in place to accommodate the efficient movement of goods and motorists in Arizona, and to support the movement of freight beyond our borders.”

PHOENIX — The new year is shaping up to be a big year for the Arizona Department of Transportation, as the agency will be working on several new and existing projects that will aid economic development and support the efficient movement of goods and services across the state.

All of the projects will be funded with federal and state highway funds, which are collected through gas and vehicle license taxes. In the Phoenix and Tucson metropolitan areas, voters have approved supplemental tax revenue that enables more transportation projects to move forward in their respective regions. 

Phoenix-Area Projects for 2015

Loop 202 South Mountain Freeway
ADOT expects to release the Record of Decision for the long-proposed South Mountain Freeway this spring and work toward selecting a contractor for the proposed $1.9 billion project. The 22-mile-long freeway would run east and west along Pecos Road and then turn north between 55th and 63rd avenues, connecting with I-10 on each end. The South Mountain Freeway is also part of the Regional Transportation Plan funding passed by Maricopa County voters in 2004 through Proposition 400. 

Loop 101 and Loop 202 Widening Projects in East Valley
Much of the focus on freeway improvements in the metro Phoenix area will remain on projects that broke ground in 2014 and are due for completion in 2016. The $73 million Loop 101 widening project between Shea Boulevard and Loop 202 (Red Mountain Freeway) in the Scottsdale area is adding an additional lane in each direction along 11 miles of the Pima Freeway, as well as merge lanes between most major interchanges. The $109 million project to widen the Loop 202 Red Mountain Freeway between Loop 101 in Tempe and Broadway Road in east Mesa also will advance, with new general purpose lanes being added between Loop 101 and Gilbert Road, along with HOV lanes between Gilbert Road and Broadway Road.

Interstate 10/Loop 303 Interchange
Among the new freeway projects scheduled to start this year is the “south half” of the Interstate 10/Loop 303 Interchange, which will complete all ramp connections between the two freeways in Goodyear. Work is expected to start this fall. The north half of the interchange opened last August and, combined with a widened Loop 303 north of I-10, has been embraced by West Valley communities as much-needed infrastructure to help drive economic development in the region. 

Additional Loop 303 Improvements in Northwest Valley
Farther north along Loop 303, ADOT will launch a project to add an interchange at El Mirage Road by this spring. The new interchange will be built at the same time that crews are improving Loop 303 into a six-lane freeway between Grand Avenue (US 60) and Happy Valley Parkway in Peoria. A third project already underway is creating improved connections at the Loop 303/Grand Avenue interchange. All three projects are scheduled for completion in 2016.

US 60 Improvements in Surprise
Also in Surprise, a project to build a Bell Road bridge over Grand Avenue (US 60) and new ramps connecting the two roadways is scheduled to start late in the year, after a design-build contracting team is selected by ADOT. 

Tucson-Area Projects for 2015 

Interstate 19 Traffic Interchange Reconstruction (Ajo Way)
In 2015, ADOT will begin work to replace the existing Interstate 19 traffic interchange at State Route 86, also known as Ajo Way, with a single-point urban interchange. The modern interchange will feature a single set of traffic signals, rather than signals at multiple locations. The $86 million project is expected to improve traffic flow and enhance safety for motorists traveling through Tucson’s southwest side. Construction is expected to continue through 2017 and will also include widening I-19 from Ajo Way to Irvington Road and widening SR 86 to three lanes in each direction between 16th Avenue and Holiday Isle.

State Route 77 Widening (Tangerine Road to Pinal County Line)
After starting work in summer 2014, ADOT will continue efforts to upgrade a six-mile section of SR 77 (Oracle Road) between Tangerine Road and the Pinal county line from two lanes to three lanes in each direction. Along with widening the roadway, planned improvements include raised medians, traffic signal and drainage improvements, wildlife crossings, sound walls and multiuse paths. The $33.9 million project is slated to take two years to complete. 

State Route 86 Widening (Valencia to Kinney Roads)
In 2015, ADOT is expected to begin construction on expanding SR 86 (Ajo Highway) in each direction from Valencia to Kinney roads in Pima County, 10 miles west of downtown Tucson. This seven-mile-long, $55 million project in Pima County will enhance safety and improve traffic flow on the highway, which serves as a regional transportation route between Tucson and south-central Arizona. SR 86 provides access to the Tohono O'odham Nation and is widely used to reach the popular tourist destination in Mexico called Puerto Peñasco, also known as Rocky Point.

Statewide Projects for 2015

Northern Arizona

US 93 Widening (State Route 71 to State Route 89 and Antelope Wash sections)
ADOT will continue long-standing efforts to transform the heavily traveled corridor between Phoenix and Las Vegas into a modern four-lane divided highway throughout the entire 200-mile stretch with two US 93 widening projects this year. After beginning last year, ADOT will complete upgrading a three-mile segment of US 93 (Antelope Wash), located approximately 20 miles north of Wikieup (mileposts 101-104) this summer. A second US 93 widening project (State Route 71 to State Route 89), just north of Wickenburg (mileposts 185-190), is expected to break ground this spring. 

State Route 89A Spot Widening (Vista Overlook to JW Powell)
This $22.5 million project is slated to improve safety and traffic flow by widening the roadway and constructing passing lanes entering and exiting Oak Creek Canyon through an eight-mile stretch from the popular tourist destination Vista Overlook to the JW Powell interchange, three miles south of Flagstaff. Design of the project is nearly complete and ADOT hopes to start construction this year.

Interstate 40 Pavement Improvements (various projects)
ADOT has several major resurfacing projects in the works along the nearly 360-mile-long I-40, which is one of Arizona’s Key Commerce Corridors, as it stretches from California to the New Mexico state line, Three major pavement preservation projects are set to take place in 2015. This spring will complete final paving on the Rattlesnake Wash to US 93 (mileposts 57-72) section east of Kingman after the project began last summer. Later this year, ADOT will start two new resurfacing projects east of Flagstaff, including the Navajo county line to Minnetonka (milepost 250-259) and Walnut Canyon to Twin Arrows (milepost 214-218) segments.

US 89 Landslide Repairs (near Bitter Springs)
ADOT is scheduled to reopen US 89 south of Page after the highway was closed on Feb. 20, 2013 after a landslide caused serious damage to the highway near the Echo Cliffs. Major work on the repairs began on Aug. 11, 2014 as crews began excavating nearly one million cubic yards of rock near the highway to build a buttress, which will stabilize and reinforce the mountain slope that carries the roadway. The $25 million repair project remains on target to reopen to traffic this spring, in advance of this summer’s tourism season in Page and Lake Powell. 

Southern Arizona

US 60 Widening (Silver King/Superior Streets)
This spring, ADOT is expected to start a project to convert the last remaining two-lane roadway segment on US 60 between Phoenix and Superior into a modern, four-lane divided highway. The $45 million project (mileposts 222-227), which will also include improving the urban section of highway in Superior, is expected to take two years to complete.

US 95 Fortuna Wash Bridge
This $13.5 million project is part of a larger corridor improvement project for US 95, the north and south corridor between Yuma and Quartzsite. US 95 is also the main route to the Yuma Proving Ground, which is one of the largest employers in Yuma County and one of the Army’s busiest training sites in the U.S. This project includes a bridge over Fortuna Wash, which often floods during heavy rains. This project is scheduled to begin in the spring.

US 95 San Luis Street Improvements
This $11 million project includes reconfiguring San Luis Port of Entry traffic off US 95 in San Luis to facilitate business along Main Street. The project, which began in October 2014, will help the circulation of traffic, enhance pedestrian safety and improve access to downtown businesses near the U.S.-Mexico international border. Work will be completed this year.

Major Studies

Interstate 11
ADOT’s Interstate 11 and Intermountain West Corridor Study continues to move forward. This year, work will begin on an Environmental Impact Statement which will allow ADOT to begin an environmental study in the area between Nogales and Wickenburg, part of the proposed Interstate 11 and Intermountain West Corridor. The $15 million Tier 1 Environmental Impact Statement is expected to take three years to complete, once work gets underway later this year. Interstate 11, which will connect Arizona to the entire Intermountain West, is one of our state’s Key Commerce Corridors. I-11 is being planned as a multimodal freight corridor and a manufacturing belt that will drive trade, commerce, job growth and economic development while facilitating strong connections to other major markets.

Passenger Rail
The next major step for ADOT’s Passenger Rail Corridor Study: Tucson to Phoenix is to publish the Draft Environmental Impact Statement for public review. Three public hearings will be held later this year in Maricopa, Pinal and Pima counties to allow community members to comment on the recommendations of the study. Following the public review process, the final recommendations and environmental considerations will be issued on the Final Environmental Impact Statement for federal approval. ADOT is currently evaluating three final rail alternatives. The Passenger Rail Corridor Study is expected to be completed later this year. ADOT’s mission is to evaluate and implement modes of transportation to provide a well-balanced, flexible transportation system that moves people and commerce throughout Arizona.

Transportation planners and engineers have a lot to consider when designing or improving a roadway in Arizona.

It’s not just about getting people from one place to the next – safety, planning priorities, community concerns, fiscal constraints all get taken into account (along with so many other factors).

There’s also a big relationship between transportation planning and the environment. In fact, that connection is so important that it’s the focus of a pretty big conference being held in Arizona this week…

The International Conference on Ecology and Transportation focuses on that correlation while showcasing research and best practices from the field. Held every two years, ICOET brings the participation of hundreds of transportation and ecology professionals from the U.S. and countries worldwide.

ADOT's booth at this year's ICOET conference showcases recent efforts.

You might remember that we blogged about the conference nearly two years ago when it was first announced ADOT, along with the Arizona Game and Fish Department, would host this year’s event.

Hosting the conference gives our state some really good exposure and the chance to show how ADOT and its partners not only build and maintain Arizona’s transportation system, but do so in a way that is sensitive to the surrounding environment.

Arizona’s wide range of ecology makes it an ideal state to host the International Conference on Ecology and Transportation. State transportation planners must take into account diverse wildlife populations and varied topography in the low and high desert plateaus as well as rocky and tree-covered mountain terrain when planning Arizona’s highway system.

During ICOET, ADOT and Game and Fish will have the opportunity to showcase joint efforts that consider the environment during the planning and building stages of transportation infrastructure. One such effort was the construction of wildlife crossing bridges and culverts as part of improvements along US 93 near the Nevada state line to reduce the number of collisions between vehicles and desert bighorn sheep. Conference participants will also learn more about wildlife crossings along SR 260, context-sensitive highway improvements in Sedona and sustainability and preservation efforts for transportation solutions at Grand Canyon National Park.

To learn more about ADOT’s efforts, check out our previous blog posts. For additional information on this year’s conference, visit icoet.net.

We just got some really exciting news about the US 93 project (you remember, it’s the one that improved about 15 miles of roadway south of the Hoover Dam – we wrote about it here and here

It was announced yesterday that the project won a regional award in the 2012 America’s Transportation Awards competition – more specifically, the project was selected as the winner in the “Best Use of Innovation, Medium Project” category!

The America’s Transportation Awards competition is sponsored by AASHTO, AAA and the U.S. Chamber of Commerce. It was created in 2008 to recognize outstanding transportation projects accomplished each year by state Departments of Transportation.

Besides “Best Use of Innovation” other categories include “Ahead of Schedule” and “Under Budget.” All the categories are divided by size, depending on the cost of the project.

Arizona’s award was announced during the annual Western Association of State Highway and Transportation Officials (WASHTO) conference. California, Nevada, Colorado, Washington and Texas also were recognized with awards.

Some background on the project
ADOT and its project team – including Federal Highway Administration, Arizona Game and Fish Department, National Park Service, Bureau of Land Management, AMEC Environment and Infrastructure, Bureau of Reclamation and FNF Construction – recognized a critical need for creative innovation during early design work preparing for the highway widening of the last segment from Interstate 40 in Kingman to the new Hoover Dam bypass bridge.

Collectively, they decided the best solution was to construct new overpasses that protected the safety of motorists and provided a passage for the desert bighorn sheep.

“ADOT and its partnering agencies worked together to achieve a common goal, which was to build a safe, modern four-lane highway for motorists, that also accounted for the unique challenges presented by the state’s geography and wildlife that make that area their home,” said ADOT Director John Halikowski.

In late 2010, ADOT completed construction of the $71.3 million project, which widened the existing roadway section from two lanes to four. Other significant highway improvements included a new trailhead, scenic overlooks and three wildlife crossings, which not only provide a crossing for the native desert bighorn sheep, but also protection for motorists.

ADOT has dedicated nearly half a billion dollars since 1998 to widen and improve US 93 from Wickenburg to the Hoover Dam. The long-term vision is to transform this route into a four-lane divided highway through its entire 200-mile stretch.

If you’ve ever driven between Arizona and Las Vegas, you’re probably pretty familiar with US 93. It’s the stretch of road traveled by countless motorists each day and it is in the midst of a major update.

A little bit of an overview
ADOT has dedicated nearly half a billion dollars since 1998 to widening and improving US 93 all the way from Wickenburg to the Hoover Dam. The long-term vision is to transform this route into a four-lane divided highway through its entire 200-mile stretch.

To turn this vision into reality, it was necessary to split the entire project into a series of smaller projects, including the one we’re blogging about today.

Milepost 2 to 17
This portion of US 93 comprises the 15 miles of roadway just south of the Hoover Dam.

In November 2010, ADOT completed construction on the $71.3 million project, which widened the existing roadway section from two lanes to four and provided significant highway improvements, including a new trailhead, scenic overlooks and three wildlife crossings, which not only provide a safe crossing for the native Desert Bighorn Sheep, but also protection for motorists.

Because this portion of the US 93 is improved, motorists now have a continuous four-lane divided highway they can drive from the new bridge all the way south to Kingman.

This project is significant because of its magnitude and the aggressive schedule crews followed to get it done on time.

“Originally it was intended to be four different projects. That 15 miles was going to be split up into four different projects, which means it would take a long time to get finished,” Kingman District Engineer Mike Kondelis said. “In 2006, we were fortunate enough to get all four of those projects lumped together and built as one project. At that point, the race was on. We wanted to be able to complete this one project in time for the opening of the Hoover Dam bypass.”

Before you take a look at the video above for more on why the bypass played such an integral part in the construction of this portion of US 93, we want to share just a few of the project stats …

  • The project required more than 3.5 million cubic yards of excavation (one cubic yard is 3 feet x 3 feet x 3 feet … that’s a major amount of material!). 
  • More than 2.9 million pounds of reinforced steel were used in the bridges and various concrete segments. 
  • This section of the project also included more than 22 miles of new guardrail and 4.5 miles of culvert pipe. 
  • The project has been recognized with some major awards, including the Arizona Chapter of the American Public Works Association Transportation Project of the Year in the $25 to $75 million category and the 2011 Arizona Transportation Partnering Excellence Award. The American Council of Engineering Companies of Arizona presented the 2011 Engineering Excellence Judge’s Choice Award to the project designer, AMEC Earth & Environmental, Inc. This project also received a couple of environmental awards, including the FHWA Exemplary Ecosystem Initiative Award and the National Environmental Excellence Award (in the conservation category) from the National Association of Environmental Professionals.

Winter weather suspends northern projects for the season

Winter weather suspends northern projects for the season

December 7, 2011

Snowy conditions from up north earlier this year.

The official start of winter is approaching, but the cold weather is already here!

Over the past few weeks, we’ve told you how ADOT prepares for the snowy conditions common this time of year in Arizona’s high country.

Getting the snowplows ready, along with plenty of deicer ready, along with closing down certain low-traffic/heavy snow routes are vital steps, but there’s an additional action ADOT takes each year as the temperatures start to dip …

Every winter ADOT has to suspend work on projects in the state’s high country. This is necessary because it is too cold to pour concrete or place asphalt pavement (rubberized asphalt is especially sensitive to temperature variations).

But that doesn’t mean our crews just drop what they’re doing!

Work is stopped at a logical point and the work zone is generally left in a condition that doesn’t impede traffic. Drivers may notice some barricades and should be aware as they’re driving through project sites.

And as for the actual crews…ADOT workers who manage or inspect the projects either switch gears to next-year’s planning or are reassigned to maintenance for the season.

Here’s a list of projects that have either already been suspended for the winter, or will be stopped in the next week or so:

  • SR 64 roadway and streetscape improvements in Tusayan
