Forest Service Roads structure standards

The standards for structures on Forest Service Roads (FSRs) in B.C. are determined and managed by the Government of B.C. The standards and guidelines for planning, building, and maintaining Forest Service Roads in B.C. cover a range of safety features like cattleguards, road gates and retaining walls.

Cattleguards, gates, and walls

The B.C. Government's structure standards have various components in use to keep roads safe including cattleguards, road closure gates, and retaining walls. More information can found in the Engineering Manual which provides design and construction standards for retaining walls, minor culverts (including log culverts), and other structures.

 Cattleguards

Cattleguards are barriers used to prevent domestic animals and some wildlife from passing along roads, while allowing the passage of vehicles and pedestrians.

Road closure gates

The Government's standard road closure gate drawings are relatively new. Feedback on the fabrication, installation, and performance aspects of the gates can be submitted to the Government at FLNREng.Branch@gov.bc.ca
