The Point: Closures will allow crews to safely continue removing support structures above the 91
Motorists traveling through Corona are advised to steer clear of full weeknight closures of westbound 91. Beginning December 2, 2024, the westbound 91 will be closed between the 71 and Green River Road on Monday through Wednesday nights as part of RCTC’s 71/91 Interchange Project. The closures are scheduled through Wednesday, December 18, 2024.
Due to the holidays, no closures will be scheduled from December 20 through January 1, 2025. Closures are anticipated to restart on Monday, January 6, 2025.
The full closure will allow crews to remove more than 40 beams of support structures that span above the westbound 91 lanes. This work requires precision and time to be completed safely. Over the summer, crews completed a similar operation with the removal of support structures over eastbound 91.
Motorists traveling on the westbound 91 and southbound 71 should plan extra time to reach local destinations and businesses in the area. Detailed closure information below:

RCTC, in partnership with Caltrans, is reconstructing the 71/91 interchange in Corona. The project will replace the single-lane loop connector between the eastbound 91 and northbound 71 with a new, two-lane, direct connector ramp. The project is anticipated to be completed in 2025.
