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.

Due to the holidays, no closures are scheduled through January 1, 2024. Closures will resume on Tuesday, January 2, 2024.

We are also informing residents and businesses of detours, traffic expectations, and to allow extra travel time.
