Jack Peters Bridge Widening & Rail Upgrade

The Jack Peters Creek Bridge Widening and Rail Upgrade Project is located on State Route 1 (SR1) in Mendocino County (post miles 51.87). The purpose of the project is to bring Jack Peters Creek Bridge up to current design standards by widening the existing structure and upgrading bridge rails. The project includes widening the bridge to accommodate two 12-foot wide lanes, two 6-foot wide shoulders and a 6-foot wide separated pedestrian walkway on the west side of the widened structure that will link the segment of the California Coastal Trail from County Road 5000 to Lansing Drive.
