The County plans to replace the low-water crossing with a full-height, full-service bridge that allows residents, emergency vehicles, and resource equipment year-round access across the Eel River. To do this, the County has enlisted the help of Quincy Engineering to design this modern, safe bridge.


Once completed, the Holmes-Larabee Bridge Replacement Project will reduce travel time by 45 minutes and will avoid travel on a steep and narrow gravel logging road across private property and prone to landslides.

Over the course of the next several years, the County and Quincy Engineering team will work together to design and construct the new bridge, which also involves obtaining environmental clearance and a variety of regulatory agency permits.

The following design alternatives were presented at the February 2019 public meeting:

Project Status

The Project is continuing the Preliminary Engineering and Environmental Study Project Development Process. Included in this update is a map that indicates the Environmental Study Limits. Please feel free to provide comments via the links on this website.
