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.
