Improvements Underway for Phase II of the State Route 60/Potrero Boulevard Interchange Project

Built on collaboration and a shared vision, Phase II of the State Route 60 (SR-60)/Potrero Boulevard Interchange Project advances to construction! On April 28, 2026, project partners, elected officials, stakeholders, and community members gathered in the City of Beaumont to break ground to celebrate a project that will improve regional and local traffic flow for motorists traveling through Beaumont and the surrounding communities.

Located between Jack Rabbit Trail and the SR-60/Interstate 10 junction, the project was designed as a key investment in regional infrastructure to improve mobility, safety, and economic growth.

"Projects like the SR-60 Potrero Boulevard Interchange symbolize the strong partnerships RCTC has with our cities and communities to build transportation infrastructure that benefits our growing region," said Raymond Gregory, Mayor of Cathedral City and Chair of RCTC. "These investments are key to keeping our region moving as our communities continue to grow."

In 2019, the City of Beaumont completed Phase I and opened the new six-lane Potrero Boulevard overcrossing above SR-60.

Phase II of the project includes:

• Construction of a six-ramp partial cloverleaf interchange at SR 60 and Potrero Boulevard
• Realignment of Western Knolls Avenue
• Widening Potrero Boulevard to six lanes, improving traffic flow and access to SR 60

The new interchange is anticipated to open to travelers in 2028. Construction crews will begin preparing the area near Potrero Boulevard bridge soon and are expected to begin construction on the new interchange in May.

The project was made possible by a mix of state and local sources comprised of the City of Beaumont's Capital Improvement Plan (CIP), Transportation Uniform Mitigation Fee (TUMF) revenues, and SB1 Trade Corridor Enhancement Program (TCEP) funds.

Throughout the duration of the project, RCTC, the City of Beaumont, and Caltrans are committed to minimizing construction impacts and providing timely updates to the public. Sign up to receive project updates or for additional project information by visiting: https://www.rctc.org/PotreroInterchange
