Title

10-0Y780: Mariposa State Route 140 Pavement Preservation

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.
