RIVERSIDE, Calif. – The Riverside County Transportation Commission (RCTC) has scheduled full closures of the eastbound 91 and southbound 15 in Corona on Sunday, October 22 from 12 midnight to 7 a.m. The full closures will allow crews to safely work on support structures and overhead signage installation for the 71/91 Interchange and the 15/91 Express Lanes Connector projects.

The full closures on the eastbound 91 will allow crews to continue to construct support structures that will extend across the 91 for the new eastbound 91 to northbound 71 connector. The new connector will replace the current loop connector when the project is complete. The 91 closures include:

• Full eastbound 91 closure from Green River Road to Serfas Club Drive, from 1 a.m. to 7 a.m.
• Full eastbound 91 Express Lane closures in Riverside and Orange Counties, from 1 a.m. to 7 a.m.
• Full westbound 91 Express Lanes in Riverside County, from 1 a.m. to 7 a.m.
• Eastbound on-ramp closure at Green River Road, from 1 a.m. to 7 a.m.

Motorists traveling eastbound on the 91 are encouraged to avoid the area by using northbound 57 to eastbound 60 to southbound 71 as routes to get around the closure.

Drivers who need to reach Green River Road or choose to use the local detour should plan for heavy delays. Travelers may use the eastbound 91 exit at Green River Road to Palisades Drive or Serfas Club Drive to re-enter the eastbound 91. Fire, police, and ambulance will have access for emergency response.

Weeknight eastbound 91 full closures will continue Monday to Wednesday nights through November 21, 2023. For more information on the eastbound 91 full closures, visit rctc.org/7191Closures.

The full southbound 15 closure is needed to allow crews to install overhead signage over I-15 near Hidden Valley Parkway. The southbound 15 will be closed from Hidden Valley Parkway to the 91 on Sunday, October 22 at midnight and reopen at 7 a.m. Motorists may use Hidden Valley Parkway to Main Street to access westbound and eastbound 91, and southbound 15. The 15/91 Express Lanes Connector started construction in 2021 and may open by the end of the year.

Motorists traveling eastbound on the 91 and southbound 15 should plan extra time to reach local destinations and businesses. Construction activity is subject to change due to weather or unforeseen circumstances.
