The Point: New lane to help provide traffic relief; watch for full closure of all 91 lanes on Friday night for sign placement
RCTC opened a new lane on westbound 91 today, helping to improve traffic flow through western Riverside County, particularly for commuters who routinely battle morning traffic congestion in the area. The new two-mile, non-tolled lane from the westbound Green River Road on-ramp in Corona to the 241 Toll Road in Anaheim was the centerpiece of RCTC’s 91 Corridor Operations Project.
The Commission began construction in November 2020 using strategic project staging with financial incentives to the contractor. This allowed RCTC to complete the project quickly and reduce the effects of construction on motorists and neighbors. Watch our video for a closer look at how this project was completed in record time and its benefit to our region.
Partners for the $29 million investment included the Orange County Transportation Authority, Caltrans, the Transportation Corridor Agencies, and the City of Corona.
Following the lane opening, additional work will be required to close out the project, including installation of a large overhead sign, which will require an overnight closure of all lanes on westbound 91 between the 71 and the 241 on Friday, January 7 at 11 p.m. to Saturday at 5 a.m.
To support this closure, the westbound 91 Express Lanes in Riverside and Orange counties, the westbound Green River Road on-ramp and off-ramp, the southbound 71/westbound 91 connector, and the northbound 15/westbound 91 Express Lanes connector will be closed starting as early as 8 p.m. on Friday.
Avoid the area or follow the detour route north on the 71, west on the 60, and south on the 57 to access westbound 91 in Orange County. Nighttime lane closures also will be needed during the coming weeks to complete the project.
The project marks one of many planned and completed along the 91 and 15 corridors to help manage traffic congestion in this growing area. RCTC continues to work with Riverside County residents on mobility solutions that connect our communities safely, reduce traffic congestion, support clean air, and promote economic prosperity in our region.
