Culvert replacement at km 40.2 Dempster highway #8 

A new 3000 mm by 49.0 m culvert will be installed via a trenchless installation methodology, and the existing 2000 mm diameter culvert shall be decommissioned via grouting. The project will involve rerouting the creek at the crossing location to accommodate flow through the new culvert and avoid potential erosion and further degradation of the existing culvert. A tunnel boring machine machine will be used, which requires land use outside the highway right of way on Gwich'in Private Lands and Territorial Lands.  See also Permit G24X001.
