Document Description
Caltrans proposes to preserve pavement along the length of the project, which includes overlaying 0.20-foot of HMA-A and placing a new structural section on dig out areas identified with local pavement failure (Appendix A-Project Layouts). The project would also replace 21 culvert systems and rehabilitate 36 existing drainage systems currently in poor condition using Cured-in Place Pipe (CIPP). Additional work would include construction of a MVP at southbound PM 12.25, replacing approximately 11,830 linear feet of guardrail with metal beam guardrail (MBGR), upgrading Transportation Management Systems (TMS) elements (signs, non-standard signs, etc.), and replacing the existing census station at PM 14.75 to meet current standards.
