U.S. 101 Paso Robles Barrier Project Barrier Separation to Adjacent System

Caltrans District 5 is planning a safety enhancement project along northbound U.S. Route 101 in Paso Robles, San Luis Obispo County, specifically between post miles 54.33 and 54.82, just north of the State Route 46 and U.S. 101 interchange. The project will install 500 linear feet of Midwest Guardrail System and 2,100 linear feet of Type 60M concrete barrier along the right side of the freeway to separate traffic from adjacent hazards, with designated openings at overside drains located at PM 54.47 and PM 54.65 to maintain drainage functionality. Two new gates will be added to the existing right-of-way fence to facilitate maintenance and inspection access. All work will remain within Caltrans’ current right-of-way and is funded under the 2026/27 fiscal year through the State Highway Operation Protection Program’s Minor A Proactive Safety – Collision Severity Reduction initiative. The project is forecasted with a posted date of July 17, 2026, and environmental coordination is led by Laura Riccardelli and Lucas Marsalek.
