Interstate 10: Ruthrauff Road Traffic Interchange

The Interstate 10/Ruthrauff Road traffic interchange will be reconstructed to improve traffic operations on both roadways.

Key elements of the project:

  • Lower I-10 to go beneath Ruthrauff Road
  • Raise Ruthrauff Road to go over Davis Avenue/Highway Drive, the Union Pacific Railroad and I-10
  • Widen I-10 to four lanes in each direction
  • Widen Ruthrauff Road to two lanes in each direction
  • Reconstruct the I-10 frontage roads to connect to the elevated Ruthrauff Road
Ruthrauff Road will close to all traffic at I-10 for up to 24 months.
Business access will be maintained throughout the project.

Project Status Update

Utility work near the interchange is currently underway. Intermittent lane restrictions are possible, but significant traffic disruptions are not anticipate during the work.

Demolition activities for the project are complete, and preliminary environmental clearances are nearly done.

The project is being advertised for bids, and ADOT expects it will be awarded to a contractor late this fall. Roadway construction is expected to begin after the holidays in early 2020. As always, schedules are subject to change.

Once a contractor is on board, ADOT will provide more specific information about the project schedules and expected staging phases.

Project Purposes

The project is designed to improve safety on both Ruthrauff Road and I-10.

Currently, passing trains stop all traffic on Ruthrauff Road, which causes backups onto I-10. In the new configuration, traffic on Ruthrauff Road will pass over the railroad and I-10, eliminating the at-grade railroad crossing.

In addition, the interchange reconstruction is part of a series of projects to increase capacity on I-10 between Ruthrauff and Ina roads.
