Southbound Eureka Slough Bridge Emergency Detour

The Southbound Eureka Slough Bridge Emergency Detour is a forecast project issued by Caltrans District 1 - Eureka for work on US Highway 101 in Humboldt County, California, specifically between Post Miles 79.75 and 80.44. Classified under NAICS code 237310, this emergency initiative focuses on implementing immediate safety measures to reduce the live load on the left side of the southbound bridge. The scope of work includes shifting vehicle traffic to the right side of the bridge, detouring bicycle traffic from the highway shoulder onto the adjacent Humboldt Bay Trail, and installing tilt meters on the bridge structure. Due to the emergency nature of the project and the necessity of maintaining public health and safety, the project has been filed with a Notice of Exemption under statutory code 15269(c). The project is described as a short-term emergency measure rather than a long-term solution. While the forecast was posted on July 2, 2026, specific contract values, performance periods, and formal solicitation numbers are not currently provided. Primary coordination is managed by an Environmental Scientist within Caltrans District 1.
