HUM 254 Culvert Rehab Project

Project Description

Caltrans aims to rehabilitate 45 existing drainage systems along Route 254, or Avenue of the Giants, from south of Phillipsville to south of Pepperwood. The existing drainage systems are rated as being in poor or critical condition and in need of repair. The project will prevent possible roadway damage, reduce sediment loads to the South Fork Eel River, and remediate fish passage barriers. Project features include new culverts, new drainage inlets, armored culvert outlets, and new bridges that will remove barriers to fish passage at Mowry Creek and Chadd Creek.

Timeline

At this time, Caltrans expects to begin construction by 2027.

Estimated Traffic Impacts

Lane closures will be required at several locations with 5-minute delays due to one-way traffic control. Bicyclists will be accommodated. A full road closure is proposed at Chadd Creek for bridge construction, which will require using U.S. 101 as a detour.
