The Riverside County Transportation Commission’s 71/91 Interchange Project will require nightly full closures (Monday – Wednesday) of westbound 91 between the 71 and Green River Rd. in Corona beginning Monday, December 2, 2024. Closures are scheduled through Wednesday, December 18, 2024.
Due to the holidays, no closures will be scheduled from December 20 through January 1, 2025. The westbound 91 full nightly closure are anticipated to restart on Monday, January 6, 2025.
