RIVERSIDE, Calif. – The Riverside County Transportation Commission (RCTC) will require nighttime full closures of the eastbound and westbound 91 to northbound 71 connectors on Monday, July 8. Motorists will not be able to access the northbound 71 from the 91 from either direction during these closures. The westbound 91 to northbound 71 connector will be closed from 8 p.m. to 4 a.m. and the eastbound 91 to northbound 71 connector will be closed from 10 p.m. to 6 a.m.

The nighttime connector closures are needed for crews to safely install overhead lighting equipment along the roadway as part of the 71/91 Interchange Project.

To reduce travel time, motorists are encouraged to plan ahead by taking regional detours. Motorists traveling to destinations along the 71 in Chino, Chino Hills, and Pomona from the 91 may use the 15, 57, and 60. These routes will help motorists avoid the 71/91 interchange and reach destinations with minimal disruption. See the regional detour map below for more details.

The southbound 71 to westbound and eastbound 91 connectors will remain open. Construction activity is subject to change due to weather or other factors.

Residents should expect traffic congestion on streets near the 91 and 71 and allow for extra time to reach area businesses. Fire, police, and ambulance services will have access for emergency response.

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.
