I-15 Express Lanes Extension Reaches Significant Milestone with Release of Draft Environmental Document

In what marks a significant milestone for the Interstate 15 Express Lanes Project Southern Extension, RCTC and Caltrans have released the Draft Environmental Impact Report and Environmental Assessment (EIR/EA) for the public to review and submit comments. The release of the Draft EIR/EA moves the region closer to relieving traffic on this part of the highway subject to project approval upon completion of the environmental process. Due to rapid population growth along the corridor and increased freight movement, traffic congestion continues to make the commute to and from southwest Riverside County difficult. The project aims to provide alternative travel choices and traffic relief to this region.

The 45-day public comment period runs from October 9 to November 26, 2024. RCTC will also be hosting three open house public meetings to provide the public information and to gather feedback from residents on the project.

The proposed project would extend the I-15 Express Lanes an additional 15.8 miles from El Cerrito Road in Corona through Temescal Valley to State Route 74 (Central Avenue) in Lake Elsinore. The project would add two tolled lanes in each direction within the I-15 median by widening the pavement and bridges and would not replace any existing lanes. The project would also add southbound I-15 auxiliary lanes between both the Nichols Road on-ramp and the SR-74 (Central Avenue) off-ramp, and between the SR-74 (Central Avenue) on-ramp and Main Street off-ramp.

Once the entire 15.8-mile length is constructed, the project would provide a reliable tolled travel time option to move motorists through this congested corridor and maintain compatibility with the regional Express Lanes network. The project would also increase opportunities for mass transit, such as RTA Express Buses and carpooling.
