Alaska Highway Deactivation
Petersen Canyon Area, British Columbia (km 679.15 - 690.50)
This project within a 10 km stretch of a former section of the Alaska Highway in northern BC required replacing the existing bridges and roadways to place the road in a self-maintaining state to protect the adjacent resources. It involved removal of five bridge structures and abutments, including two bridges that spanned over 100 feet, replacing two bridges with fords traversable by 4×4 pickup truck, regrading and installation of rip rap, removal of 22 deep culverts, re-establishment of natural drainage patterns, stabilizing the road prism to reduce impact of sediment transport and removal of all debris.
Additional Scope Items
- Environmental protection plan, including high erosion risk procedures.
- Instream equipment outfitted with biodegradable oils, greases and hydraulic fluids.
- Disposal of creosote timbers and steel girders.
- Catchment system to keep debris away from watercourses.
- Temporary bridges.
- Berms, roads, cross ditches, water bars and ditch block construction.
- Involved indigenous construction company equipment and labour force.
