PLAN AHEAD FOR WESTBOUND 91 CLOSURESDecember 11, 2023 - January 24, 2024
The Riverside County Transportation Commission’s 71/91 Interchange Project will require nightly full closures (Monday through Wednesday) of the westbound 91 between State Route 71 and Green River Road beginning Monday, December 11, 2023 through Wednesday, January 24, 2024.
Due to the holidays, no closures will be scheduled from December 20 through January 1, 2024. Closures will resume on Tuesday, January 2, 2024.
These closures will allow crews to safely continue building support structures and placing beams for the new eastbound 91 to northbound 71 connector. Crews are building a 30-foot-tall structure over the 91 and setting more than 200 beams over the eastbound and westbound 91 lanes.

The Riverside County Transportation Commission, in partnership with Caltrans, is reconstructing the 71/91 Interchange Project in Corona.
The new non-tolled interchange is designed to improve safety, expand access to other modes of travel, reduce greenhouse gas emissions, enhance traffic flow, and support continued movement of native wildlife through the area. Construction will take place from early 2023 to 2025.
