OVERVIEW

The Riverside County Transportation Commission (RCTC) in partnership with the city of Beaumont and Caltrans is leading final design and construction on “Phase 2” of the State Route 60/Potrero Boulevard Interchange Project. This phase includes designing and constructing a six-ramp partial cloverleaf interchange, extended ramp acceleration and deceleration lanes, and realignment of Western Knolls Avenue.

The project will:

  • Provide the residents and businesses access to the growing communities in the area
  • Enhance traffic efficiency and connectivity on the SR-60 corridor
  • Improve air quality by reducing congestion

The proposed project will restripe the overcrossing to accommodate six lanes and expand the existing Potrero Boulevard overcrossing to add off-ramps, loop on-ramps, and traffic signals to the partial cloverleaf configuration interchange. Approximately one mile of auxiliary lane will be added at the ramps, three retaining walls will be constructed, and the bridge over San Timoteo Creek will be widened.

This project is funded by state and local funding including city of Beaumont Capital Improvement Plan (CIP), Transportation Uniform Mitigation Fee (TUMF), and SB1 Trade Corridor Enhancement Program (TCEP) Program funding.

The City of Beaumont completed construction of Phase 1 of the project in December 2019. This included the construction of a 6-lane Potrero Boulevard overcrossing over State Route 60. Phase 2 of the project currently in final design.

Construction is expected to begin in late 2025. The interchange is anticipated to open to motorists in late 2027.
