Nov. & Dec. Weekend Closures:

91 Express Lanes & General Purpose Lanes

The Riverside County Transportation Commission is continuing to upgrade the 91 Express Lanes with new state-mandated transponder technology.

This work requires weekend closures of the 91 Express Lanes and intermittent weekend closures of up to three general-purpose lanes. Please expect delays, avoid the area and allow extra travel time.

Due to the dynamic nature of construction or in case of inclement weather, this work may be rescheduled. For more information and the complete closure schedule,  visit Weekend Closures and Restriping.
