As part of the Riverside County Transportation Commission's (RCTC) 91 Project, crews will work on the 15 and 91 for approximately two weeks to stripe the new Express Lanes and finalize general purpose lanes, weather permitting. During this time, multiple lanes and ramps will be closed. Message signs will alert motorists of ramp closures. Additional Construction Alerts will provide details, and information will be posted to project social media.
Please note that lane reductions may begin one hour prior to the nightly closures. Expect significant delays, allow extra travel time and use alternate routes if possible.
