Riversiders traveling westbound on the 91 through Corona should prepare for detours and delays this December. The Riverside County Transportation Commission (RCTC) is moving forward with its 71/91 Interchange Project, requiring nighttime closures of westbound 91 between State Route 71 and Green River Road.
When to Watch Out
Closures will take place Monday through Wednesday nights from 10 p.m. to 4 a.m., starting December 2. During these times, RCTC crews, in partnership with Caltrans, will remove over 40 support beams spanning the westbound lanes—a meticulous and safety-critical task.
Plan Ahead
David Knudsen, RCTC's Deputy Executive Director, advises drivers to avoid delays by using alternate routes. "To avoid getting stuck in traffic, we recommend taking northbound 71 to westbound 60 to southbound 57," Knudsen said.
Holiday Break and Next Steps
Closures will pause from December 18 to January 2, 2025, for the holidays, resuming January 6. The current phase is expected to wrap up by January 22, 2025.
What’s the Goal?
This $137 million project will replace the single-lane loop connector between eastbound 91 and northbound 71 with a new, two-lane direct connector ramp, easing congestion and improving safety. The full project is slated for completion in 2025.
