DN 101 Culvert Rehabilitation and Fish Passage

The California Department of Transportation (Caltrans) proposes the Culvert Rehabilitation and Fish Passage Project on U.S. 101 between Post Miles M0.0 and 46.5 in Del Norte County. The project would rehabilitate 19 drainage systems and remediate fish passage at two of the locations. 

Timeline

Construction is expected to begin in 2029.

Traffic Impacts

Expected short-duration traffic delays when culverts are being replaced and longer delays at the proposed bridge on Mello Creek. Lane closures and delays of up to 20 minutes are anticipated.
