91 Freeway Bottleneck: Crews Begin Work On New Westbound Lane

CORONA, CA — A $29 million construction project designed to relieve bottleneck traffic on the westbound 91 Freeway in Corona got underway Monday.

The State Route 91 Corridor Operations Project will add one westbound lane for approximately two miles between the Green River Road on-ramp and the southbound 241 connector, according to the Riverside County Transportation Commission, which is overseeing the project.

The new lane is being built next to the outer shoulder and is expected to open in late 2021.

This week's construction activities include getting equipment, signs, fencing, and K-rail in the area.

The first phase of construction — retaining walls and other improvements along Green River Road — will last about 10 months, according to the RCTC.

Motorists are asked to watch for lane closures, narrower lanes, construction crews and equipment, and changing conditions on the 91 and Green River Road.

The RCTC is working in partnership with Caltrans, the Orange County Transportation Authority, the Transportation Corridor Agencies, and the City of Corona, to build the 91 Corridor Operations Project.
