BEAUMONT, Calif. – The Riverside County Transportation Commission (RCTC) and City of Beaumont jointly held a groundbreaking ceremony on April 28, marking the start of construction of Phase II of the State Route 60 (SR‑60)/Potrero Boulevard Interchange Project. The groundbreaking event brought together regional transportation partners, elected officials, stakeholders, and community members.
“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.”
“By easing congestion on State Route 60 and local streets, we’re helping residents spend less time in traffic and more time with their families,” said City of Beaumont Mayor Jessica Voigt. “These improvements will help people and goods move more safely and efficiently — now and into the future.”
Designed as a key investment in regional infrastructure, Phase II will improve mobility, safety, and economic growth in the City of Beaumont. Building on the success of Phase I, completed by the City of Beaumont in 2019, which introduced a new six-lane Potrero Boulevard overcrossing over SR-60, this project will significantly improve both regional and local traffic flow by providing access to SR-60 for residents and businesses.
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 funding for Phase II is provided from a mix of state and local sources, including the City of Beaumont local funds, Transportation Uniform Mitigation Fee (TUMF) revenues, and SB1 Trade Corridor Enhancement Program (TCEP) funds. Together, these funds make it possible to deliver this $64 million transportation project.
Construction crews will begin preparing the area near Potrero Boulevard bridge soon and are expected to begin construction on the new interchange in May with the new interchange anticipated to open to travelers in 2028.
RCTC, the City of Beaumont, and Caltrans remain committed to minimizing construction impacts and keeping the public informed throughout the duration of the project. To sign up to receive project updates or for additional project information, please visit: www.rctc.org/PotreroInterchange
