PHOENIX — Two years after a landslide ripped apart a 500-foot section of US 89 and split the communities of Bitter Springs and Page, the Arizona Department of Transportation anticipates reopening the highway to traffic in the early evening of Friday, March 27, barring any potential weather delays or mechanical breakdowns during the paving process, which began today.

Page Unified School District buses are expected to be the first vehicles to pass through newly rebuilt roadway. Students from the Bitter Springs and Marble Canyon areas have been among the most impacted by the US 89 closure, which has remained in place following the Feb. 20, 2013, geologic event approximately two miles north of the US 89/US 89A junction near the community of Bitter Springs.

Following the paving of Temporary US 89 in August 2013, US 89T has served as the detour route for motorists headed to and from the Page and Lake Powell areas, but residents and students in the Bitter Springs and Marble Canyon communities have still had to go out of their way to travel to and from Page and Lake Powell.

“The reopening of Highway 89 is great news for Page Unified School District and the families that we serve in the communities of Marble Canyon, Bitter Springs and Cedar Ridge,” said Page Unified School District Superintendent Jim Walker.   “The district will be now be able to re-establish our traditional bus runs to these communities, which will reduce the time that some of these children spend on our buses by up to an hour on a one-way trip.  I would like thank our families for their efforts to continue to support their children’s school attendance during this very challenging time.”

Prior to the March 27 reopening, crews will be completing the paving, install rumble strips and guardrail, and add temporary striping and pavement markers along the roadway.

Prior to launching the $25 million repair project last summer, which included removing approximately one million cubic yards of rock material to realign the roadway and construct a downslope rock buttress at the base of the Echo Cliffs to stabilize the area, ADOT had to clear several hurdles to move the project forward.

The ultimate repair of US 89 is the final step in fulfilling ADOT’s three-pronged approach to the US 89 landslide incident, which included providing immediate emergency access, conducting a geotechnical investigation and restoring essential traffic to the area. Paving US 89T (Navajo Route 20) has been the short-term solution for motorists driving to and from Page.

“ADOT recognizes the importance of this corridor and what it means to the communities of Bitter Springs, Cedar Ridge and Marble Canyon,” said ADOT Intermodal Transportation Division Director Steve Boschen. “While the Feb. 20, 2013, landslide event was certainly unexpected and a severe blow to the area, it was a reminder about how critical transportation infrastructure is to the motorists, businesses, local residents and schoolchildren who rely on it every day.”

After an extensive geotechnical assessment identified the necessary repairs in July 2013, ADOT retained an engineering firm and developed plans for the eventual repair; finalized all federally required environmental reviews that included cultural, biological and water quality measures; and completed plans for the required right-of-way easements.

ADOT, along with the Federal Highway Administration, Navajo Nation, Navajo Division of Transportation and the Bureau of Indian Affairs, were able to expedite the environmental, utility and right-of-way clearance process, knowing that the use of US 89T was a temporary fix, especially for the  Bitter Springs area  communities.

The US 89 landslide repair project is eligible for reimbursement through the Federal Highway Administration’s emergency relief program, which provides funding to state and local agencies for the repair or reconstruction of highways, roads and bridges that are damaged in natural disasters and catastrophic failures.

The landslide-damaged stretch of US 89 has come a long way in the past two years...

You might remember that an early morning landslide on Feb. 20, 2013 caused a section of the roadway to buckle near Page – back then, the road looked like this.

Before crews could even begin repairing the road, ADOT provided immediate emergency access in the area and kicked off an extensive geotechnical investigation. ADOT also paved US 89T (formerly Navajo Route 20) to serve as the detour for motorists driving to and from Page. In addition, there were environmental, utility and right-of-way processes to complete. Around that time, a long-term repair solution was identified.

Work did get started last summer and has included moving about 1 million cubic yards of rock and dirt. Crews have removed the material to construct a downslope buttress to stabilize the area.

Now, 24 months after the landslide, progress is clearly visible, as you can see in the video above.

So, what’s left to do?

Not all that much, considering how big of a project this has been.

“We’ve entered the final phase of the project,” says ADOT Senior Resident Engineer Steve Monroe. “We’re now starting to actually rebuild the road itself. They’ll bring in some aggregate base, put several layers of that down, wet it down, compact it, wet it down, compact it, get that all in place. After that, we can start paving. When that’s finished, then there will be a half-inch of friction course, just another layer of asphalt that goes on. Then we can come back do the final striping, put in the recessed pavement markers, the rumble strip and then we’ll have it opened up to traffic before the summer tourist season.”

Find the latest on the project, by visiting some of our previous posts. Don’t forget to stay tuned ... we’ll continue to share US 89 details here and we look forward to blogging about the grand reopening.

Crews on the US 89 landslide repair project have moved a lot of dirt and rock over the past six months…

To be exact, they’ve moved one million cubic yards of material! The work has included almost daily drilling and blasting operations in order to realign the roadway and construct a downslope rock buttress to stabilize the area. In the slideshow above, you can see photos that were taken on the project site just last month – check out the heavy-duty equipment required for the massive effort.

Project milestone
Right now, crews are done with the earthwork and will be moving on to the final phase of the project to restore the highway.

Substantial work has been completed and crews started this week on building the foundation of a newly-realigned 1,500-foot section of US 89. Once the subgrade is finished, the roadway can then be paved.

With the completion of the earthwork and construction of the buttress, ADOT remains on target to reopen the highway prior to the busy summer tourism season in the Page/Lake Powell area.

Looking back
It was two years ago this month that the roadway suffered serious damage following a landslide on the early morning of Feb. 20, 2013 and has remained closed after a 500-foot section of roadway buckled in Echo Cliffs, two miles north of the US 89/US 89A junction near the community of Bitter Springs.

To read about the project’s progress over the past two years, please revisit our previous posts.

PHOENIX — Six months after extensive earthwork started on removing nearly one million cubic yards of rock material as part of the repairs of the US 89 landslide-damaged highway south of Page, the Arizona Department of Transportation is moving onto the final phase of the project to restore the highway.

The roadway suffered serious damage following a landslide on the early morning of Feb. 20, 2013 and has remained closed after a 500-foot section of roadway buckled in Echo Cliffs, two miles north of the US 89/US 89A junction near the community of Bitter Springs.

Since Aug. 11, 2014, crews have been conducting almost daily drilling and blasting operations in order to realign the roadway and construct a downslope rock buttress to stabilize the area.

Substantial work has been completed and crews started this week on building the foundation of a newly-realigned 1,500-foot section of US 89. Once the subgrade is finished, the roadway can then be paved.

February 5, 2015

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.

Cameron roadway improvement project update

Cameron roadway improvement project update

January 9, 2015

We’ve got an update for you today on a project we first told you about last summer.

Work started about a year ago to expand US 89 from two lanes to four lanes through the community of Cameron within the Navajo Nation, about 60 miles north of Flagstaff.

As you can see in the video above, things are progressing...

“They’ve completed the roundabout at Highway 64 and US 89, so traffic’s utilizing that,” says project supervisor Rick Schilke in the video. “We finished up most of the northbound alignment, so we switched traffic onto the northbound so we can start the southbound.”

Work also includes the removal and replacement of the existing Cameron Truss Bridge with two new bridges (one going north and one headed south) at that location.

“The (new) bridge itself won’t be in use until probably the end of March,” Schilke says in the video. “It’s currently a two-lane bridge that was built in 1959. It’s a steel truss bridge that’s only 26-feet wide curb to curb and there’s no pedestrian walkways on it. The new bridge will be two 12-foot lanes with shoulders and a six-foot walkway on the east side and then, once that’s complete, we’ll take down the existing bridge all the way to below the surface and build an almost identical bridge without the walkway for southbound.”

Additional project improvements include new sidewalks, streetlights and four pedestrian/livestock underpasses.

See additional photos of the project on ADOT’s Flickr page.

Yesterday, we took a look at the US 89 landslide repair project from above. Today, we have another angle to show you…

To really get an idea of the progress being made, you’ll want to pay close attention to a couple of areas on the screen.

Before and after images of US 89 landslide repair.

First, take a look at the cliffs above the damaged roadway. Notice how the much the formation has changed by the end of the video? That’s because crews are removing material from that area above the slide and trucking it below to build a stabilizing buttress. As we explained in this previous post, crews are utilizing heavy-duty equipment, a fleet of enormous trucks and explosives to get the job done.

A rendering of the repair plan.

You’ll also want to take note of the buttress itself at the base of the slope. Once complete, the buttress will act as a wall-like support structure composed of rock material. In the video above, you can see how it’s coming along. See the graphic at left for good rendering of the overall repair plan.

The one-minute, 22-second video above actually represents about three and a half months of work…

In that time, crews on the US 89 landslide repair project have been busy blasting and moving dirt and rock material. By the end of the project, they’ll have moved about one million cubic yards!

Before and after images of US 89 landslide repair.

If you’ve been following us for a while, you know that the repair work includes moving the roadway alignment about 60 feet away from the landslide area and stabilizing the new road by constructing a downslope buttress. That buttress is being created with the material that’s being excavated from the landslide area (read more about the repairs in this previous post). ADOT anticipates completion of the US 89 repair and opening the new segment for travel by early summer, 2015.

Check back with us tomorrow, here on the blog. We’ve got another time-lapse video that shows the US 89 landslide repair work from another angle!

Ever wonder what it takes to move one million cubic yards of rock and dirt?

Turns out you need plenty of heavy-duty equipment, a fleet of enormous trucks and a lot of explosives (detonated by trained professionals, of course).

Oh yeah, you also need some time...

Those big trucks you see in the video above have been working since the summer on the landslide-damaged section of US 89, about 25 miles south of Page. By April 2015, ADOT contractors (and their trucks) will have moved the million cubic yards of material from above US 89 to build a stabilizing buttress below.

You can check out our previous blog post to learn more about that buttress, along with additional repair details. The landslide occurred back in February 2013. Since that time, ADOT conducted a major geotechnical investigation and worked diligently to restore mobility to the area by paving Navajo Route 20/US 89T, a 44-mile route that is serving as a detour for motorists heading to and from Page and the Lake Powell area.

US 89 Cameron Roadway Improvements (Sept. 2014)

Earlier in the summer, we told you about the US 89 Cameron roadway improvements. Today, we wanted to bring you a quick update…

You’ll remember that ADOT started working in March to expand US 89 from two lanes to four lanes through the community of Cameron within the Navajo Nation, about 50 miles north of Flagstaff.

Besides the road widening between SR 64 and the Little Colorado River (mileposts 464-467), major work for this project includes the removal and replacement of the existing Cameron Truss Bridge with two new bridges (one going north and one headed south) at that location. Additional improvements include constructing a roundabout at the existing intersection of US 89 and SR 64, new sidewalks, streetlights and four pedestrian/livestock underpasses.

Progress is being made

You can get a good look at the project’s progress in the photo slideshow above. Right now, crews are working to complete the roundabout by October. As you can see, pedestrian crossings are being constructed and the bridge is really coming along – the first bridge’s deck will be poured in the spring.

Construction traffic impacts

During this first phase of construction, all traffic will remain on its current alignment. For the second phase of work (anticipated in summer 2015), all traffic will be moved onto the newly constructed roadway.

Drivers should know that at least one travel lane in each direction will remain open during construction at all times. There may be roadway closures; however, they are not generally expected to exceed 15 minutes. Warning signs and flaggers for both north- and southbound traffic may be used at times.

ADOT advises motorists to be alert for construction equipment and personnel, and to proceed through the work zone with caution.

It’s anticipated that this project will be complete by fall 2016. For more information, please check out the project Web page.
