2024 will be a busy year for Phoenix-area freeway projects

PHOENIX – The Arizona Department of Transportation will start or continue making progress on several Phoenix-area freeway construction or maintenance projects during 2024.

The new year will see the launch of two Loop 101 widening projects as well as advancements on improvement projects that are underway along Interstate 10 near the Broadway Curve and along Interstate 17 north of Phoenix.

The following are among the major freeway projects ADOT will work on in 2024:

• Loop 101 (Pima Freeway) Improvement Project between Shea Boulevard and Princess Drive/Pima Road in Scottsdale. The project is scheduled to start on Jan. 5 and include the addition of a lane in each direction within a 4.5 mile work zone. Crews also will convert the Loop 101 interchange at Frank Lloyd Wright Boulevard into a diamond configuration to improve traffic flow. The project is scheduled to be completed in approximately two years. More information: azdot.gov/Loop101PrincessToShea         
• Loop 101 (Agua Fria Freeway) Improvement Project between I-17 and 75th Avenue in the northwest Valley. The two-year project is scheduled to start in fall 2024 and include the addition of a lane in each direction. Other work will include interchange and cross-street improvements at 75th Avenue.

• I-10 Broadway Curve Improvement Project between the I-17 “Split” and Loop 202 in Chandler. The largest freeway reconstruction project in ADOT’s history started in fall 2021 and is slated for completion near the end of 2024. Crews will finish elevated ramps providing direct connections between I-10 and State Route 143 (Hohokam Expressway) and complete lanes carrying local traffic in areas between Baseline Road and 40th Street. The project improves travel on 11 miles of one of the Valley’s busiest stretches of freeway. More information: i10broadwaycurve.com            
• I-17 Improvement Project between Anthem Way and Sunset Point north of Phoenix. Work on the 23-mile project started in fall 2022. Crews are adding third lanes in each direction between Anthem Way and Black Canyon City as well as a unique 8-mile flex lanes system north of Black Canyon City. Improvements are scheduled for completion by late 2025. More information: improvingi17.com
• I-10 Gila River Bridges Project southeast of Riggs Road. The project, which will reconstruct the outdated existing I-10 bridges crossing the Gila River, is scheduled to start in spring 2024 and take approximately two years to complete. 
• I-17 Resurfacing Project between Happy Valley Road and State Route 74 in north Phoenix. A project to improve pavement conditions along I-17 is scheduled to start in spring 2024 and take approximately seven months to complete.

ADOT plans and constructs new freeways, additional lanes and other improvements in the Phoenix area as part of the Regional Transportation Plan for the Maricopa County region. Many projects are funded in part by Proposition 400, a dedicated sales tax approved by Maricopa County voters in 2004.
