ABOUT THE PROJECT

The Riverside County Transportation Commission (RCTC) and the City of Beaumont, in partnership with Caltrans, are constructing “Phase II” of the State Route 60/Potrero Boulevard Interchange Project. This phase will deliver major roadway and interchange improvements to improve traffic flow and access to and from SR-60, strengthening connections and regional mobility in Beaumont and across western Riverside County.
