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

The “91 Refresh” work took place from summer of 2022 through the fall of 2023.
