The full closures of southbound 71 were completed on Friday, April 4. Thank you for your patience as we work to deliver the 71/91 Interchange Project.
Weeknight full closures (Monday – Friday) of southbound 71 at Butterfield Ranch Rd/Euclid Ave to the 91 are scheduled Monday, March 3 through Friday, April 4, 2025. The southbound 71 to eastbound and westbound 91 connectors will also be closed.
The closures are scheduled to take place from 9 p.m. to 5 a.m., Monday through Thursday nights, and midnight to 6 a.m. on Friday nights.

The Riverside County Transportation Commission, in partnership with Caltrans, is reconstructing the 71/91 interchange 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.
