CANCELED: 56-Hour Full Closure Of Westbound 91 Freeway

SEE JAN. 21 UPDATE: High Winds Cancel This Weekend’s Full Closure Of Westbound 91

RIVERSIDE COUNTY, CA — Motorists are being asked to avoid state Route 91 in Corona this weekend, otherwise they will experience "significant delays," officials are warning.

All westbound 91 lanes between McKinley Street and Main Street in Corona will be closed from 9 p.m. Friday, Jan. 21, to 5 a.m. Monday, Jan. 24, so crews can put support structures over the freeway as part of the Riverside County Transportation Commission’s 15/91 Express Lanes Connector Project, it was announced Wednesday.

The westbound 91 Express Lanes in Riverside County and the westbound 91 McKinley Street on-ramp also will be closed throughout the weekend, and lanes will be reduced on eastbound 91 on Saturday night and Sunday morning, according to the RCTC.

"If work cannot be performed this weekend for weather or staffing reasons, it will be rescheduled promptly," the agency said.

Alternate routes will be available during the closures: Motorists can head north on Interstate 15, exit at Hidden Valley Parkway, enter southbound I-15, and head west on the 91. Another option is to head south on I-15, exit at Magnolia Avenue, enter northbound I-15, and continue west on the 91. A third option is to exit at McKinley, travel west to Magnolia, enter northbound I-15, and head west on the 91. See a detour map below.

RCTC, in partnership with Caltrans, began construction of the 15/91 Express Lanes Connector Project in April 2021 to build a link between the new 15 Express Lanes and the 91 Express Lanes. The $270 million project is designed to help reduce traffic congestion, improve safety due to less weaving among lanes, and improve travel time reliability between the two tolled facilities, according to the agencies. The connector is expected to open in 2023.

Three additional weekend connectors will be scheduled to place and remove more support structures for the connector during 2022 and 2023.
