State Route 140 Mariposa Pavement Preservation

construction is anticipated to begin in spring 2023.

The California Department of Transportation (Caltrans) proposes to extend the service life of State Route 140 from post miles 25.3 to 51.8 in Mariposa County and provide a smoother riding pavement surface by resurfacing the roadway with 0.25-foot of hot mix asphalt (Type A). The work would also replace non-standard guardrails and bridge approaches with concrete end blocks where appropriate. The project will install traffic monitoring devices such as traffic count stations, rumble strips and pavement delineation.
