August 14, 2015

PHOENIX — Drivers who normally use the Loop 101 (Pima Freeway) on- and off-ramps at the 90th Street interchange in the Scottsdale area should plan on alternate routes for a couple of months starting Sunday (Aug. 16), according to the Arizona Department of Transportation.

All four of the Loop 101 ramps at 90th Street/Pima Road are scheduled to be closed at approximately 2 p.m. Sunday (Aug. 16) as part of the ongoing freeway-widening project between Shea Boulevard and Loop 202 (Red Mountain Freeway).

The ramps at 90th Street will be reconstructed to fit into the path of the wider freeway. The ramps are due to reopen by mid-October.

90th Street will remain open to through traffic under Loop 101 unless work requires temporary closures. 90th Street will be closed at Loop 101 from 5 a.m. to 2 p.m. Sunday while crews set up the ramp closures.

Drivers are encouraged to use ramps at other nearby interchanges, including Shea Boulevard or Via De Ventura.

Ramps at other Loop 101 interchanges, including Indian School and Indian Bend roads, already are closed for reconstruction work. The ramps at Indian School Road are scheduled to reopen by August 21, while the ramps at Indian Bend Road are due to reopen in mid-September.

ADOT has worked with the Salt River Pima-Maricopa Indian Community and the city of Scottsdale in coordinating a number of the recent ramp closures during the summer months, when lighter traffic conditions occur.

The work is part of the $73 million project to add new right lanes along Loop 101 between Shea Boulevard and Loop 202 (Red Mountain Freeway). The entire project is scheduled for completion next year.

Project schedules are subject to change due to inclement weather.

It’s been a while since we last checked in on the Loop 101 widening project, so we thought we’d take a look and see how work is progressing…

You might remember that construction began in early August 2014 and is expected to wrap up in late 2016. When work is complete, Loop 101 will be widened from Shea Boulevard to the Loop 202 (Red Mountain Freeway) interchange. In addition to the new travel lanes (one in each direction) from Shea Boulevard to McKellips Road, the project also includes:

Two additional travel lanes from the northbound Loop 101/Loop 202 interchange entrance ramp to McDowell Road
Traffic-interchange improvements
New rubberized asphalt on the roadway surface from Shea Boulevard to McKellips Road

Crews constructing a retaining wall near the southbound on-ramp at 90th Street.

Right now, the project is roughly 42 percent complete and crews are really taking advantage of the summer months – when there’s less traffic and fewer big events – to get a lot of work done.

Northeast Valley drivers have likely noticed a few ramp closures within the project’s span.

ADOT Transportation Engineering Specialist David Locher explains that those closures are necessary so that crews can move/relocate the ramps outward so they’ll be able to align with the new expanded freeway exit/entrance lanes. Locher says the goal is to have all the ramps finished by January.

Currently, 60-day ramp closures are in place at McDowell (closure began June 1), Indian School (June 22) and Indian Bend (July 13). Drivers should also prepare for an upcoming 60-day closure at the 90th Street/Via Linda on- and off-ramps that will begin Aug. 10.

The project also includes 11 bridges…

Crews use the paving machine at night.

Crews have completed most of the bridge work, says Locher, but they still have to wrap up construction on the bridge approaches. Speaking of bridges, if you haven’t already seen it, you might want to check out this video from back in March that shows how (and why) crews lowered a new lane on the bridge at 90th Street.

As you can see from the aerial photos above, crews are continuing day and night to expand the freeway lanes along the length of the project.

“ADOT is working hard to ensure drivers won’t have to wait long to experience a less congested and quieter ride,” ADOT Senior Community Relations Officer Felicia Beltran said.

Nesting birds are protected during construction

Nesting birds are protected during construction

Nesting birds are protected during construction

May 26, 2015

Cliff and Barn Swallow facts.

Typically, we’re asked about driver licenses, project timelines, vehicle registration and even ramp meters, but we hardly ever get questions about bird nests.

So, when we found out that someone had in fact submitted a bird nest question to ADOT’s constituent services officer, we knew we had to share the answer on this blog.

The inquiry concerned nests built by cliff and barn swallows (you’ve likely seen them before – they’re mostly made out of mud and are found under eaves or bridges). Someone who regularly jogs near the Loop 101 widening project wanted to know why the nests under the freeway bridges had been removed.

ADOT biologists were able to explain that the birds are protected by the Migratory Bird Treaty Act and that ADOT’s Environmental Planning Group reviews all projects before assigning measures to protect nesting birds from harm during construction.

In many instances, ADOT goes in to remove old, EMPTY nests from a project site before work begins, but after the birds have gone south for the year (they only nest here during the spring and summer months). This was the case on the Loop 101.

Cliff Swallow Nesting Stages

If work is happening during nesting season, the birds will often try to rebuild, even on a bridge structure that’s under construction.

When that happens, the nesting mud must be removed by contractors on a daily basis to prevent nest completion.

“We can remove the nests as they’re building them without harming the birds,” said ADOT Biologist Joshua Fife, adding that contractors are given training on what to look for and are instructed to not remove nests that are farther along and may contain eggs or nestlings.

On some projects, the team may also install exclusionary measures such as netting or plastic to prevent the birds from building nests.

After construction is complete, the birds are free to build their nests again and ADOT stays out of their way because the mud doesn’t impact our structures.

If you’re interested in birds, you might like this post that explains how ADOT keeps birds away from project site water sources near airports.

Phoenix and ADOT open Loop 101 interchange at 64th Street

May 18, 2015

PHOENIX – The Loop 101 interchange at 64th Street in northeast Phoenix opened to traffic as planned today (May 18) following a city of Phoenix project to construct a new section of 64th Street between Mayo Boulevard and the Pima Freeway.

The Phoenix Street Transportation Department worked with the Arizona Department of Transportation on final preparations before crews opened the Loop 101 on- and off-ramps at 64th Street.

Phoenix activated new traffic signals at 64th Street and Mayo Boulevard last week. Traffic on the 64th Street Bridge is regulated by “all-way” stop signs.

The city’s contractor completed sign installation and lane-striping along eastbound Loop 101 approaching the interchange on Sunday.

The Loop 101 interchange at 64th Street was completed in 2008 as part of the Maricopa Association of Governments’ Regional Transportation Plan approved by county voters in 2004. The opening of the on- and off-ramps was contingent upon the city’s plans for constructing 64th Street between the freeway and Mayo Boulevard.

ASU landscape architecture students get Loop 101 tour

ASU landscape architecture students get Loop 101 tour

May 5, 2015

ADOT Project Landscape Architectural Designer Joe Salazar shows paint samples to the students.

Learning doesn’t always have to take place inside of a classroom, sometimes it can happen safely near the side of a freeway!

That’s where a group of ASU students received a “behind the scenes” tour, packed with details on how ADOT’s Roadside Development section provides landscape, architectural and environmental technical design direction for projects statewide.

After sitting in on a morning construction meeting, the students – all juniors who are working toward their degrees in landscape architecture – were given a tour of the Loop 101 improvement project. The project, which will add new lanes in both directions of Loop 101 between Shea Boulevard and Loop 202 in the Scottsdale and Salt River Pima-Maricopa Indian Community, proved to be an excellent one to showcase.

“It’s an ideal example of all the aspects ADOT gets involved with … it contains everything,” said ADOT Project Landscape Architectural Designer Joe Salazar.

Just north of Chaparral Road, the students stopped to see the project's plant salvaging operation.

Yuri Lechuga-Robles, an ADOT intern with Roadside Development and also a student in the ASU class, helped to initiate the tour and agreed that the project was a good one to highlight.

“The project is one that the students were aware of, but probably never thought they’d be able to see from the inside. For that reason, it was a really good choice,” he said, adding that before beginning his internship at ADOT, he didn’t realize how much input goes into a project. “For me, the tour was an opportunity for my classmates to get a glimpse of what the projects are all about … just to have them see the size of the team that it requires was important.”

The first stop on the tour was off Loop 101, just north of Chaparral Road. Here, the students saw the project’s plant salvaging operation, where the cacti and trees that were removed for construction live for the project’s duration. The thousands of Ironwoods, Ocotillos and Saguaros are watered and cared for in the makeshift nursery until they can be replanted when the project nears completion.

ADOT’s Chief Landscape Architect LeRoy Brady told the students that many factors are vital when replanting salvaged Saguaros. Research has shown that Saguaros fare much better if they’re replanted at the same, exact depth they were originally growing – even just a few inches deeper can result in loss, he said.

Thousands of Ironwoods, Ocotillos and Saguaros are watered and cared for in the makeshift nursery.

The next stop was off the freeway at McDonald Drive for a look at the project’s paint pallet and decomposed granite samples. Salazar explained how ADOT worked with the community to determine the colors, which are all earth tones.

The tour concluded with a review of the project’s architectural design at the 90th Street bridge and a look how surrounding neighborhoods can be integrated into ADOT projects using walkways, bike lanes, equestrian trails and landscaping.

That community collaboration was definitely a big theme for the day…

Before the tour even began, students got the chance to hear from representatives from the Salt River Pima-Maricopa Indian Community.

SRPMIC Director of Community Relations Janet Johnson talked to the students about the meaning behind some of the symbols and artwork being used on the project. Terrollene Charley, of the SRPMIC Planning Services Division explained it is important to the community that the project’s landscaping reflects the indigenous desert surroundings.

The community collaboration made an impression on the students.

Cesar Del Castillo said he especially liked seeing how the surrounding communities play a part in the project.

Student Shane Ohlhausen agreed, saying he enjoyed the exposure to public works and being able to hear from the SRPMIC.

“It was a good experience,” he said.

Check it out: Loop 101/90th Street bridge time lapse

March 18, 2015

Loop 101 is being widened from Shea Boulevard to Loop 202, and within that span, there are several bridges that get additional lanes. However, one of those bridges – the one at 90th Street – required a little more work than the others.

For one thing, it’s curved. That means precast girders, ones that are prebuilt offsite, weren’t an available option for the lane additions. So, crews had to build the components at the project location, which required falsework (we’ve blogged about falsework before, but if you need a refresher: falsework gives temporary support to a structure until it can carry its own weight).

That falsework, which is what crews constructed the additional Loop 101 lane on top of, hangs lower than the final height of the bridge and had to be built high enough to give adequate clearance to the traffic traveling below on 90th Street.

Still with us?

To recap, the necessary falsework meant that crews had to build the new lane a few feet above its eventual resting spot and, as you can see in the video above, when the lane construction was finished, they had to lower it into place.

That covers why the lane was lowered, now let’s look at how it all got done.

ADOT Transportation Engineering Specialist David Locher explains that lowering the new lane was accomplished with the help of four jacks – each rated at 250 tons.

“We use very strong jacks,” he said. “We just lifted the lane ever so slightly so that we could remove some of the timbers (part of the falsework) at a time.”

Locher said that the road was lowered in three-inch increments until it was in place about 13 hours later.

In the coming months, crews will pour concrete to connect the new lanes to the existing bridge. After that, they’ll build the roadway deck on top.

One more thing…

ADOT is expanding Loop 101 on both the southbound and northbound sides, but you might notice in the video above that only the northbound side of the freeway had to be lowered.

Wondering why?

Locher explains that the southbound side was actually high enough to clear traffic because it is built on a banked curve. The slight incline gave crews the space they needed to build the additional southbound lane without having to elevate the falsework.

PHOENIX — As part of the Loop 101 Improvement Project in the East Valley, additional on- and off-ramps will be closed for approximately two months starting Monday (March 9), according to the Arizona Department of Transportation.

The northbound Loop 101 on- and off-ramps at Thomas Road are scheduled to close by early Monday morning. Crews will reconstruct the ramps so they fit into the path of the wider freeway. The ramps are due to reopen by mid-May.

Drivers are encouraged to use ramps at other nearby interchanges along Loop 101 while the ramps at Thomas Road are closed.

The work is part of the $73 million project to add new right lanes along Loop 101 between Shea Boulevard and Loop 202 (Red Mountain Freeway). The entire project is scheduled for completion next year.

The northbound Loop 101 on-ramp and southbound off-ramp at McKellips Road were closed to traffic last week. They are scheduled to reopen by early May.

Project schedules are subject to change due to inclement weather.

Transportation projects in 2015 to drive economic development in Arizona

Transportation projects in 2015 to drive economic development in Arizona

Transportation projects in 2015 to drive economic development in Arizona

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.

Loop 101 project update

Loop 101 project update

Loop 101 project update

November 26, 2014

Work is progressing on the Loop 101 widening project we first told you about in August (and then again in September).

As northeast Valley drivers have surely noticed, crews are currently working to widen bridges within the project area and build retaining walls and sound walls.

The $73 million project will widen 11 miles of Loop 101 between Shea Boulevard and Loop 202 (Red Mountain) with the addition of one new lane in each direction. A second new northbound Loop 101 lane also will be constructed between the Loop 202 interchange and McDowell Road. Other project features include the addition of new merge lanes between interchanges, new lighting and signs, new landscaping (including the use of hundreds of salvaged cacti and other plants), wider freeway bridges and realigned on- and off-ramps and a new layer of rubberized asphalt.

Why we build new lanes when we do

You might be wondering why we’re building the new lanes now, as opposed to years ago when the Loop 101 was first constructed. We get that question a lot from people who say building everything all at once would prevent the restrictions, closures and traffic that can come along with new construction.

You can find a great answer in this blog post from 2011. But in a nutshell, we can tell you that it’s just not feasible to construct freeways for future needs all at one time. The main reason has to do with funding. The money for projects is not available all at one time. As a result, we build and improve freeways in phases, using the funding that is available when the project is scheduled to begin. In Maricopa County, that funding comes from the voter-approved, 20-year extension of the half-cent sales tax (2006-2026). Revenue is programmed for freeway projects identified in the Maricopa Association of Government’s Regional Transportation Plan, a long-term blueprint for transportation improvements across the Valley.

What drivers should know

There will be no closures during the upcoming holiday and any lane restrictions will be limited to overnight hours. Drivers can also rest assured that no construction-related closures are planned during a number of upcoming events in the area (including the Super Bowl and Spring Training). For more on this project’s timeline, check out this blog post.

Finally, and most importantly, drivers need to be aware that they’re driving through a work zone and must obey the lower speed limit that has been posted.

“It’s 55 MPH,” says ADOT Public Information Officer Doug Nintzel in the video above. “It’s there for (driver) safety. It’s there for the safety of our workers.”
