Award: Interstate improvements
Value: 410 million dollars in total
Location: Between Phoenix and Tucson, Arizona
Customer: Arizona DOT
State leaders tapped a group of construction companies to improve a vital desert corridor, a key project for the region’s manufacturing and logistics hubs.
The Arizona DOT recently contracted the Coffman-Fisher design and construction team to deliver the northern segment of the I-10 Wild Horse Pass Corridor Improvement Project.
The team, made up of Coffman Specialties of San Diego and Fisher Sand & Gravel of Dickinson, North Dakota, as well as Stantec Consulting Services, will cover about 12 miles of I-10 in Arizona, according to a Feb. 11 news release from Stantec.
The $410 million project is part of the corridor’s global program valued at approximately $1 billion, the statement said. Once completed, the upgraded interstate will reduce congestion by up to 126,000 vehicles per day, as well as improve driver safety in each direction.
“The I-10 corridor serves as a vital connector between Tucson and Phoenix, and we welcome the opportunity to help improve the connectivity of these communities,” said Robert Lemke, senior project manager for Edmonton, Alberta-based Stantec, in the statement. “Working together with ADOT and Coffman-Fisher as a design and construction partner, we are providing a safer and more connected travel experience throughout Arizona.”
The improvements will include the addition of one general use lane and one high-occupancy vehicle lane in each direction from Loop 202 to south of Riggs Road. Crews will also build a general purpose lane in each direction from Riggs Road south to the Gila River bridges.
To do this, the design and construction team created an alternative approach to the originally proposed corridor improvement plans of repaving with new asphalt.
Crews will replace the entire section with concrete. Doing so should provide a 30-year lifespan at nearly the same cost as new asphalt, resulting in “significant long-term maintenance savings,” according to the release.
Other interchange modifications will occur at Wild Horse Pass, Queen Creek, Riggs Road and Koli Road. Additional improvements include intelligent transportation systems, lighting, signs, signage, pavement markings and drainage improvements throughout the corridor, according to the release.
