Here are the routes to avoid during the SR-91 closure

91 Freeway closed to start construction on new interchange project

Officials are closing the 91 Freeway this week to start the 71/91 Interchange Project in Corona.

Officials hope that the new, non-tolled connector will improve safety, expand access to other modes of travel, reduce greenhouse gas emissions, enhance traffic flow and help foster the native wildlife movement. 

The interchange will not be fully finished until 2025.

The express lanes will also be closed from I-15 to the County Line from 8 p.m. until 4 a.m. 

The Riverside County Transportation Commission advised drivers to use the 71 Freeway and the 60 to 57 Freeways to get around the construction. Motorists who need to access Green River Road should use the Auto Center Drive and Serfas Club Drive exit to Palisades Drive.

Westbound 91 will be partially closed on Thursday between 8 p.m. and 4 a.m. as well as Friday between 9 p.m. and 6 a.m.  Its express lanes from the I-15 to the County Line will close once again during the same time frame on Thursday.
