The Arizona Department of Transportation plans to begin or continue several Phoenix-area freeway construction and maintenance projects during 2024.
Improvements are part of the Regional Transportation Plan for the Maricopa County region and are partially funded by Proposition 400, a sales tax voters approved in 2004.
Major freeway projects include:
On Jan. 5, work will begin on the Loop 101 Improvement Project between Shea Boulevard and Princess Drive/Pima Road in Scottsdale. Work includes adding a lane in each direction within a 4.5 mile work zone and converting the Loop 101 interchange at Frank Lloyd Wright Boulevard into a diamond configuration.
In the spring, work will begin on the I-10 Gila River Bridges Project southeast of Riggs Road. The project will reconstruct the outdated existing I-10 bridges.
Also in the spring, work will begin on the I-17 Resurfacing Project between Happy Valley Road and State Route 74 in north Phoenix. The project will improve pavement conditions.
In the fall, the Loop 101 Improvement Project between I-17 and 75th Avenue in the northwest Valley will begin. Work includes adding an addition in each direction, and interchange and cross-street improvements.
Work continues on the I-17 Improvement Project between Anthem Way and Sunset Point north of Phoenix.
