Construction is underway on the State Route 71/91 Interchange Improvement Project, which is designed to improve safety, enhance traffic flow, and improve accessibility in Riverside County’s most heavily traveled corridor.
The Riverside County Transportation Commission (RCTC) is in partnership with Caltrans in the reconstruction of this major interchange in the City of Corona, which serves as a gateway between Riverside, Orange, and San Bernardino counties, and is a vital link for commuters and freight vehicles that travel along State Routes 91 and 71.
The new non-tolled interchange is designed to improve safety, expand access to other modes of travel, reduce greenhouse gas emissions, and enhance traffic flow. The project will support continued movement through this area by native wildlife such as mountain lions, bobcats, and coyotes.
RCTC awarded the $120-million contract to Skanska to perform the work, with the project scope including:
- Replacement of the existing single-lane loop connector between eastbound 91 and northbound 71 with a new, two-lane, direct connector ramp;
- Construction of an eastbound 91 auxiliary lane to improve access to the new direct connector to northbound 71;
- Realignment of the eastbound 91 on-ramp from Green River Road to improve access to the 71/91 interchange; and
- Realignment of southbound 71 to create space for the new direct connector.
“Completing this project will provide welcome relief for our residents, especially those returning to Riverside County during afternoon hours on eastbound 91,” said Bob Magee, chair of the Riverside County Transportation Commission.
