Project Description

Glenn County will replace four structurally deficient or functionally obsolete bridges within a one-mile corridor of County Road 67 between County Road Z and the Butte County Line in two Phases.

Phase 1 - 2024

Bridge No. 11C-0017
Bridge No. 11C-0179

Phase 2 - 2025

Bridge No. 11C-0015
Bridge No. 11C-0016


The bridge replacement projects will require the closure of County Road 67 from County Road Z to Aguas Frias, maintaining agricultural field access.

A Detour Plan will be in place to advise motorist of road closure and suggest alternate routes. Glenn County will make every effort to keep the community updated on the progress of the work and any additional changes to the traffic patterns.
