TUCSON — Crews began demolishing an eastbound Interstate 10 bridge that started carrying traffic over Ruthrauff Road in 1965.
The Interstate 10/Ruthrauff Road traffic interchange is being reconstructed to improve traffic operations on both roadways. The project is expected to be completed by the summer of 2021.
Westbound I-10 traffic is now getting through the work zone on the westbound frontage road, while eastbound I-10 traffic has been shifted to the old westbound lanes.
The Arizona Department of Transportation says some temporary sections of pavement allow three lanes of traffic to flow in each direction. Access to all businesses in the area is being maintained with other temporary changes to the frontage roads.
Key elements of the project include:
- 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.
