Closures Ahead: Westbound 91 Main Street Ramps and Lane Reductions

Saturday, November 12 – Monday, November 21

The westbound 91 Main Street on- and off-ramps, the 15/91 connectors, and the lanes on westbound 91 reopened on Sunday, November 20, about 20 hours ahead of schedule.


Full closures of the westbound 91 Main Street on-ramp and off-ramp and lane reductions on westbound 91 and on the northbound I-15 to westbound 91 connector in Corona are needed for crews to continue to safely repave lanes in this area. This extended closure period will help reduce the number of remaining weekend full closures required for the Riverside County Transportation Commission’s 91 Refresh Project. Heavy traffic delays are expected, and motorists should avoid the area, follow detours, and allow for extra travel time.

When:

Weeklong Closures: Saturday, November 12 at 10 p.m. through Monday, November 21 at 4 a.m. Dates and times are subject to change and rescheduling, due to weather and other factors.

The Riverside County Transportation Commission, in partnership with Caltrans, is repaving lanes and making repairs to sound walls and associated concrete barriers along the outer portions of eastbound and westbound 91 in Corona. Work will take place mainly between the Lincoln Avenue interchange and Interstate 15, an area with a long history of roadway settlement. This work is part of an ongoing investment in the heavily traveled 91 corridor.
