Interstate 10: Ruthrauff Road Traffic Interchange

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

I-10-Ruthrauff-TI-Map

Key elements of the project:

  • Lower I-10 to go beneath Ruthrauff Road/El Camino del Cerro
  • Raise Ruthrauff Road/El Camino del Cerro 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/El Camino del Cerro to two lanes in each direction
  • Reconstruct the I-10 frontage roads to connect to the elevated Ruthrauff Road/El Camino del Cerro

Ruthrauff Road/El Camino del Cerro will close to all traffic at I-10 for up to 24 months.

Business access will be maintained throughout the project.

Anticipated Project Timeline

Mid-Jan. 2020

  • Construction begins

Winter/Spring 2020

  • Interchange closure begins

Late Summer 2021

  • Ruthrauff Road/El Camino del Cerro reopens over I-10

(the interchange/ramps will not be open)

Late 2021

  • Interchange reopens to traffic

During the interchange closure, motorists will need to use alternate routes to access I-10.

ADOT will maintain access to businesses throughout the project. The Chuck Huckelberry Loop will remain open throughout the project.

Project Purposes

The project is designed to improve safety on both Ruthrauff Road/ El Camino del Cerro 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.
