Interstate 10: Signal project at Kolb, Rita and Wilmot roads

The Arizona Department of Transportation is scheduled to begin a signal project at the Interstate 10 interchanges at Kolb, Rita and Wilmot roads this summer.

The project involves installing traffic signal systems at each of the I-10 interchange ramps on the three roadways.

Motorists may encounter occasional days due to lane closures and traffic shifts while work is underway.

The work will be completed in phases through late spring 2019 with down time between the different phases.

In addition to the signal systems, the project includes the following improvements:

  • Pavement and median adjustments
  • Curb and gutter work
  • Americans with Disabilities Act-compliant sidewalks and ramps (where needed)
  • Updated lighting

Crews will also modify the eastbound exit ramp at Rita Road. The existing “flying Y” for southbound traffic will be replaced with a more traditional right turn lane.

Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.
