Southbound Eureka Slough Bridge Emergency Detour

Caltrans District 1 in Eureka is preparing for an emergency project to address immediate safety concerns on the southbound Eureka Slough Bridge by reducing live load on its left side. To accomplish this, vehicle traffic will be permanently shifted to the right side of the bridge, while bicycle traffic will be rerouted from the highway shoulder onto the adjacent Humboldt Bay Trail to ensure continued safe passage. As part of the safety mitigation, tilt meters will be installed on the bridge to continuously monitor structural movement and provide real-time data for ongoing assessment. The project is forecasted with a posted date of July 2, 2026, and is being managed by the California Department of Transportation with Felicia Zimmerman, Environmental Scientist, serving as the primary point of contact for inquiries. The work is located in California and is categorized as an emergency response action requiring prompt implementation to safeguard public infrastructure and users.
