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.
Two replacement options are being examined. Alternative 1 would replace the old bridge with a new two-lane bridge 30’ upstream. Alternative 2 would replace the old bridge with a new two-lane bridge approximately 150’ downstream.
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.

The following items will be addressed as part of this project:
- Construct a new two-lane bridge that spans Bear River
- Remove the existing bridge
- Improve the hydraulic clearance under the bridge
- Correct the roadway approach
- Increase load capacity
