Dog Bar Road over Bear River


The Dog Bar Road Bridge over the Bear River (Bridge No. 17C-0031) carries two-way traffic on a one-lane bridge, connecting Placer County and Nevada County. The bridge is located on the Placer-Nevada County Line. The narrow bridge with a curb-to-curb roadway width of 13’-8” does not meet standards for bridge cross sections. In addition, the approach roadway has sharp curves at each end of the bridge, resulting in frequent vehicle impacts to the bridge railing. Caltrans has approved Highway Bridge Program (HBP) funding to remove and replace the bridge. Located upstream from the existing route, the replacement bridge will have two lanes and include a sidewalk.

Bridge History

The existing bridge was designed by the U.S. Forest Service and constructed in 1934. The original timber deck and railing was replaced in 2000 with a corrugated steel deck filled with asphalt concrete and metal railing. This single lane bridge is listed in Caltrans Historical Bridge Inventory as not eligible for National Historic Places.

Final IS/MND

A Final Initial Study with proposed Mitigated Negative Declaration has been approved by the Nevada County Board of Supervisors and is available here.
