RIVERSIDE, Calif. – The Riverside County Transportation Commission (RCTC) advises motorists traveling on westbound 91 in Corona to stay alert for full westbound 91 closures between State Route 71 and Green River Road. The full nighttime westbound 91 closures will occur Monday through Wednesday nights beginning Monday, December 11, and continuing through January 17, 2024, as part of the 71/91 Interchange Project.

Due to the holidays, no closures will be scheduled from December 20 through January 1, 2024. Closures will resume on Tuesday, January 2, 2024.

Motorists traveling on the westbound 91 and southbound 71 should plan extra time to reach local destinations and businesses in the area. Closures include:

• Full closure of westbound 91 lanes from the 71 to Green River Road, Monday through Wednesday from 10 p.m. to 4 a.m.
• Full westbound 91 Express Lanes closures from the 15/91 Interchange to the Orange County/Riverside County Line, Monday through Wednesday from 8 p.m. to 4 a.m.
• Full southbound 71 to westbound 91 connector closure, Monday through Wednesday from 9 p.m. to 5 a.m.
• Full southbound 15 to westbound 91 Express Lanes connector closure, Monday through Wednesday from 8 p.m. to 4 a.m.
• Full northbound 15 to westbound 91 Express Lanes connector closure, Monday through Wednesday from 8 p.m. to 4 a.m.
• Westbound 91 Green River Road off-ramp closure, Monday through Wednesday from 9 p.m. to 4 a.m.

To reduce traffic time, motorists traveling westbound are encouraged to avoid the area by using northbound 71 to westbound 60 to southbound 57 to navigate around the closure.

Drivers who need to reach Green River Road may use the westbound 91 exit at Serfas Club Dr./Auto Center Dr. Fire, police, and ambulance will have access for emergency response. Construction activity is subject to change due to weather or unforeseen circumstances.

Similar to the eastbound 91 full closures that occurred this fall, the westbound 91 closures will allow crews to safely continue construction of support structures and formwork for the new connector. The support structures for the new connector will be approximately 30 feet in height with more than 200 beams being positioned during these weeknight closures.
