Heavy Traffic Delays On Tap This Weekend Due To 91 Freeway Closures

CORONA, CA — If you are planning to use state Route 91 this weekend, you might want to reconsider.

The Riverside County Transportation Commission’s 71/91 Interchange Project will require lane and ramp closures June 9-12, according to the agency.

"Motorists should avoid the area," the RCTC reported.

The weekend shutdown schedule is:

• All eastbound 91 lanes will be closed from Green River Road to Serfas Club Drive, early Saturday, Sunday, and Monday mornings.
• The eastbound and westbound 91 Express Lanes in Riverside County will be closed the entire weekend.
• The eastbound 91 Green River Road on-ramp will be closed nightly starting at 9 p.m. to support the full closures of the lanes.

The southbound 71 connectors to eastbound and westbound 91 will remain open. The eastbound and westbound 91 general-purpose lanes will remain open during daytime hours, the RCTC reported.

The closures will allow construction crews to safely lift a large support structure in the 91 median, place it in a pre-drilled hole, and pour concrete to form the foundation for one of the support columns for the new interchange, according to RCTC.

"Heavy traffic delays are expected approaching Corona in the early morning hours," the agency reported. "Additional delays are expected throughout the weekend due to the 91 Express Lanes closures in Riverside County. Drivers are strongly urged to avoid the area by using Routes 57 and 71 to access Route 60, to allow extra time, and to consider using Metrolink as a regional travel alternative."
