The Interstate 10 Highland Springs Avenue Interchange Project, informed by preliminary studies conducted in partnership with Caltrans and the cities of Banning and Beaumont, would reconfigure lanes to the I-10 underpass at Highland Springs Avenue and add auxiliary lanes to the ramps to improve traffic flow and safety.

The interchange serves as the main connection to large housing developments and multiple retail, commercial, medical, and employment centers. With one of the highest peak traffic volumes per hour and per month in Riverside County, it also is in proximity to State Route 60, a major trucking and logistics route for southern California and the nation.

RCTC completed the Project Study Report/Project Development Support document in 2021. Engineering and environmental studies are expected to be under way from summer 2022 to 2024. Once funding and environmental approvals are secured, construction could begin in 2026. RCTC is seeking federal, state, and local funding sources.
