Riverside County Transportation Commission
Riverside County – As part of the Riverside County Transportation Commission’s (RCTC) 91 Project, westbound and eastbound lanes on the 91 between the 71 and Main Street in Corona will be narrowed in width, starting June 1.
Dubbed the “91 Corona Squeeze,” the narrower lanes will continue for about 10 months to allow crews to widen the roadway safely and efficiently behind K-rail. The four inside lanes will be restriped to 10.5 feet in width, and the outside or “slow lane” will be 12 feet wide.
Restriping will occur at night as follows:
• Westbound 91: June 1-4 from 8 p.m. to 4:30 a.m.; June 5 from 10 p.m. to 6:30 a.m.; and June 6 from 11 p.m. to 8 a.m.
• Eastbound 91: June 1-4 from 9 p.m. to 5:30 a.m.; June 5 from 11:30 p.m. to 7:30 a.m.; and June 6 from 11:59 p.m. to 8:30 a.m.
Following the restriping, crews will place K-rail along the outside lane in one-mile segments. This will eliminate the shoulder within these segments. In areas where there is no K-rail, there will be a shoulder for emergency use. Freeway Service Patrol assistance will be increased during the “91 Corona Squeeze.”
Drivers are reminded to:
• Follow the 55 MPH speed limit and note that fines are doubled in construction zones
• Allow extra travel time and be alert to changing conditions
• Watch for signs about upcoming narrower lanes
• Be aware of nearby motorcycle riders; motorcyclists should be extremely cautious, particularly if splitting lanes
• Adjust travel plans to off-peak hours, if possible, or use alternate routes
• Carpool or use public transit, when feasible
Led by RCTC, the 91 Project is adding regular lanes, tolled express lanes, auxiliary lanes and direct express connectors from the northbound 15 to the westbound 91 and from the eastbound 91 to the southbound 15. Improvements to interchanges, ramps, lanes and surface streets also will be made along the 91 between the Riverside County/Orange County Line in Corona and Pierce Street in Riverside. The new lanes are expected to open in 2017.
