BEAUMONT, Calif. – The City of Beaumont and the Riverside County Transportation Commission (RCTC) are pleased to announce that RCTC is taking the lead on two key infrastructure projects in Beaumont: Phase II of the SR-60/Potrero Boulevard Interchange Project and the initial planning and feasibility phase for the I-10 / SR-79 (Beaumont Avenue) Project.

These critical infrastructure projects, led by RCTC in partnership with the City of Beaumont, will enhance regional mobility, improve traffic flow, and drive economic growth throughout the entire San Gorgonio Pass Area. The Phase II Potrero Boulevard expansion and I-10 / SR-79 (Beaumont Avenue) Project are key to improving connectivity and supporting the region’s continued development.

The SR-60/Potrero Boulevard Interchange Project, located between Jack Rabbit Trail and the SR-60/Interstate 10 junction, will continue with major improvements in Phase II including:

• Widening Potrero Boulevard on both sides of SR-60 to six lanes;
• Adding two direct on-ramps, two loop on-ramps, and two direct off-ramps; and
• Realigning Western Knolls Avenue with Potrero Boulevard north of the proposed interchange.

Additionally, RCTC, the City of Beaumont, and Caltrans are collaborating to improve the I-10 / SR-79 (Beaumont Avenue) interchange and nearby roads in Beaumont. This critical area is a hub for both local traffic and commuters traveling through Riverside, Orange, and Los Angeles counties, as well as freight moving across the Western U.S. These proposed improvements aim to ease traffic and enhance connectivity for everyone traveling through this vital intersection.

“These projects are a major step forward in improving mobility for our residents and businesses,” said Mayor Mike Lara. “By investing in major infrastructure, we are not only improving daily travel for our residents, but we are laying the foundation for future development that benefits our entire community,” said Councilmember Lloyd White, who also served as the Past Chair of RCTC.

“RCTC is proud to take the lead on these projects that will help improve the lives of residents in Beaumont and the surrounding communities, and for commuters traveling through this busy corridor,” said Supervisor Karen Spiegel, Chair of RCTC and Vice-Chair of the Riverside County Board of Supervisors. “The collaboration between RCTC, the City of Beaumont, and Caltrans will help deliver these vital transportation projects to shape the future of travel in Riverside County.”

Construction for the SR-60 / Potrero Interchange Project is anticipated to begin in September 2025, pending approval by Caltrans and construction bid advertisement and award by RCTC. The City is committed to keeping residents and businesses informed throughout the entire process to minimize disruptions.
