Arizona is on track to receive a $54M federal grant helping fund two key widening projects, and adding traffic-management technology that includes a dust storm detection and warning system, along Interstate 10 between Phoenix and Tucson.

Members of Arizona’s congressional delegation have informed the Arizona Department of Transportation that the U.S. Department of Transportation has recommended awarding the FASTLANE grant under a program established by the 2015 FAST Act. This highly competitive program made $800M in federal funds available to state departments of transportation.

Formal notification of FASTLANE grants is expected after a 60-day congressional review period.

The anticipated award is for three projects on I-10 between Phoenix and Tucson:

  • Realigning and widening four miles in the Picacho area to three lanes in each direction while reconstructing the interchange with State Route 87.
  • Widening four miles between Interstate 8 and Earley Road to three lanes in each direction while upgrading ramps at Jimmie Kerr Boulevard near Casa Grande.
  • Making technology enhancements to improve traffic management and safety, including remote sensors to provide early warning of approaching dust.

The total cost of the I-10 improvement projects is $157.5M. ADOT will provide $103.5M of that amount.

The U.S. Department of Transportation evaluated 212 applications from states requesting a total of $9.8 billion for transportation projects, more than 10 times the available funding.

The two I-10 widening projects in the FASTLANE grant are included in ADOT’s 2017-2021 Five-Year Transportation Facilities Construction Program, which the State Transportation Board adopted in June. These two projects were accelerated from ADOT’s six-to-10-year development program due to additional funding through the Fixing America’s Surface Transportation Act.

Once the two I-10 widening projects are complete, ADOT will have reached its goal of widening the entire stretch of I-10 between Casa Grande and Tucson to a six-lane divided highway.
