Document Description
The California Department of Transportation (Caltrans) proposes to improve safety, operations, and mobility on SR 49 in Nevada County from post mile 10.8 to R13.3 through the addition of northbound and southbound truck climbing lanes outside an urbanized area, 14’-22’ median with barrier, 8’-10’ shoulders, right turn lanes, and two at-grade access-controlled intersections. This project will be built in three phases of construction based on funding availability. This project will improve safety, operations, and mobility of vehicular traffic, pedestrians, and cyclists on SR 49 by: 1) Constructing northbound and southbound truck climbing lanes / segments of auxiliary lanes to improve operations, 2) Reducing the severity and frequency of collisions at public road intersections and roadways, 3) Reducing cross-centerline collisions, 4) Improving the roadway to meet current design standards and improve vertical curve sight distance, 5) Providing a 12’ x 12’ animal crossing that would assist in avoiding collisions between vehicles and animals, 6) Implementing identified improvements in the Nevada County Active Transportation Plan, which identifies SR 49 as needing Class III bicycle facilities and providing adequate shoulders for disabled vehicles and California Highway Patrol enforcement activities.
