Yankee Jims Bridge over the

North Fork American River Bridge Replacement


Section 4(f) De Minimis Findings
Open for Public Comment until May 13th 2024

A majority of the Project is located within Auburn State Recreation Area and therefore is an action that is subject to Section 4(f) of the U.S. Department of Transportation Act of 1966.

Project Description

Placer County Department of Public Works, in cooperation with the Federal Highway Administration and Caltrans, proposes to build a new arch suspension bridge adjacent to the existing Yankee Jims Bridge 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 improve emergency access and provide a safer evacuation route between Colfax and Foresthill. The existing Yankee Jims Bridge will be kept in place.

A Notice of Preparation for a Draft Environmental Impact Report, in compliance with the California Environmental Quality Act, was held for the project in February of 2020. At this time two alternatives were being considered, a steel plate girder bridge and an arch suspension bridge. Since this time, the project team has completed a comprehensive analysis and ultimately selected the arch suspension bridge as the preferred alternative.
