Interstate 10: Ruthrauff Road Traffic Interchange

The Interstate 10/Ruthrauff Road traffic interchange has fully reopened to traffic


Key elements of the project included:

  • Lowering I-10 to go beneath Ruthrauff Road/El Camino del Cerro
  • Raising Ruthrauff Road/El Camino del Cerro to go over Davis Avenue/Highway Drive, the Union Pacific Railroad and I-10
  • Widening I-10 to four lanes in each direction
  • Widening Ruthrauff Road/El Camino del Cerro to two lanes in each direction
  • Reconstructing the I-10 frontage roads to connect to the elevated Ruthrauff Road/El Camino del Cerro

Project Purposes

The project is designed to improve safety on both Ruthrauff Road/ El Camino del Cerro and I-10.

Prior to the project, passing trains stopped all traffic on Ruthrauff Road, which caused backups onto I-10. In the new configuration, traffic on Ruthrauff Road passes 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.
