Eureka Slough Bridges Replacement Project

Eureka Slough Bridges Replacement Project

Caltrans proposes to replace the existing northbound and southbound Eureka Slough bridges (Bridge Nos. 04-0022L&R) in Humboldt County on U.S. Highway 101 (U.S. 101) from Post Miles (PMs) 79.5 to 80.2. The purpose of the project is to replace the two existing bridges that cross over Eureka Slough with two new structures that meet geometric and seismic standards while providing safe multi-modal access. Two Build Alternatives and a No Build Alternative are proposed. Alternative 2A would replace both bridges on the existing alignment utilizing a temporary bridge for traffic and Alternative 2B would replace the northbound bridge on the existing alignment and the southbound bridge adjacent to the existing southbound bridge while utilizing the existing bridges for traffic.
