Southwest Region ADA Features Upgrades

The Arizona Department of Transportation, in coordination with the Federal Highway Administration, will be upgrading sidewalks, curb ramps, and driveways across the southwest district. ADOT evaluated existing feature conditions and will upgrade approximately 120 features to comply with the latest ADA guidelines (Americans with Disabilities Act). 

Expect to see crews at work in different parts of the Southwest District which include Parker, Quartzsite, Tonopah, Gila Bend and Yuma.


Phase 1 in the Town of Parker was completed in Fall 2021.

Phase 2 will begin in Quartzsite and is scheduled for Summer 2022.

Construction will take place in multiple areas which include:

  • Interstate 10 between mileposts 4.68 and 5.06.
  • State Route 10B between mileposts 19.55 and 19.78.
  • State Route 95 between mileposts 109.05 and 110.62
  • US 95 between mileposts 104.06 to 104.07.
Project Fact Sheet

ADOT will provide more specific information about project schedules and potential impacts as it becomes available.

The nature of a design-build project is to design elements of the project while other elements are under construction, making it different from a typical project that goes into construction after the design process is complete. This allows for a shorter project duration and reduced costs. Access to all businesses, schools, and residences at all time during this multi-phase project will be maintained.

What to expect:

Drivers should expect possible delays at times throughout the project and should consider alternate routes.
