Document Description
The California Department of Transportation (Caltrans) proposes to partially replace and seismically retrofit the northbound U.S. 101 Eel River Bridge from post miles 53.7 - 54.2 near Rio Dell, Humboldt County, California. This bridge was identified in the Structure Replacement and Improvement Needs (STRAIN) Report as a seismically vulnerable bridge. This project will improve the structural integrity of the bridge so it can withstand a seismic event while also improving a non-standard curve at the southern approach to the bridge. The project would replace Spans 1 through 4 of the northbound Eel River Bridge with a castin-place (CIP) prestressed box girder bridge (Appendix A). The remaining Spans 5 through 8 would be seismically retrofitted. Additional work would include constructing a retaining wall to realign the northbound bridge approach.
