Document Description
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 would improve drainage facilities within the existing right-of-way and install traffic monitoring devices such as traffic count stations, rumble strips and pavement delineation. Eleven culverts would be replaced at the following post miles: 38.07, 39.62, 44.39, 45.2, 45.67, 47.0, 47.19, 48.19, 49.2, 50.07 and 50.86. A new culvert would be installed at post mile 43.8. The project would improve non-standard dikes and rock slope protection.
