OVERVIEW

The I-15 Interim Corridor Operations Project was the result of an agency task force led by staff from RCTC, Caltrans, the City of Corona, and the County of Riverside. The group began meeting in June 2021 to study alternatives and develop near-term improvements to help improve traffic operations. The CHP also provided input regarding safety and vehicle pull-over locations.

The project added a non-tolled lane to southbound I-15 between the Cajalco Road on-ramp and the Weirick Road off-ramp, a distance of just under one mile. To add the lane, crews strengthened the pavement of the outer and inner I-15 shoulders to handle traffic loads. Crews restriped the roadway to provide three 11-foot wide lanes, one 12-foot wide lane, a varying 3 to 8-foot wide outer shoulder, and a varying 2 to 5-foot wide inner shoulder. The new lane opened July 23, 2022.

Work began May 23, 2022, and the new lane opened on July 23, 2022. Closeout activities were completed in fall 2022.

RCTC completed engineering and environmental studies, as well as the project design, in early 2022. RCTC awarded a construction contract on March 9, 2022. Work began May 23, 2022, and the new lane opened on July 23, 2022. Closeout activities were completed in fall 2022.
