Yankee Jims Bridge over the North Fork American River

I

Project Description

Placer County Department of Public Works, in cooperation with the Federal Highway Administration and Caltrans, proposes to replace the existing bridge that crosses over the North Fork American River. The existing bridge is structurally deficient based on a Caltrans Bridge Inspection, which prohibits emergency vehicles from using the bridge. The new bridge will increase emergency access and provide a safer connection between Colfax and Foresthill. The existing bridge will be kept in place.

Two bridge alternatives are being considered, each option would be immediately downstream of the existing bridge and would require road and site accommodations to complete construction.
