Document Description
The purpose of the Project is to address the deficiencies of the existing Hopper Slough Bridge using current Caltrans geometric standards that would provide the traveling public with a safer highway. As part of the project, Caltrans proposes two alternatives to replace the current bridge with a new longer bridge that has two 12-foot travel lanes, two 6-foot shoulders and a barrier rail that meets current standards. Additionally, a culvert would be replaced, the roadway between postmile 5.0 and 5.2 would be repaved, and guardrails would be replaced with new Midwest guardrails.
