The article describes the construction of a 53-mile road across tundra, in which pipes, geotextiles, and shotrock were used to resolve drainage problems. Specifications called for fill placement primarily during the winter so that construction equipment could be used on the tundra without damage to the insulating tundra mat. The need for culverts with seams strong enough to resist the forces of frost heave and differential permafrost settlement led to the selection of continuous welded-seam corrugated steel pipe. Research indicated that it performed as well as riveted heavy-gauge pipe, and could be manufactured quicker. A 200-man crew hauled 694 pieces of equipment to meet a 2000-ft per day schedule in constructing the road. Thaw pipe was installed inside the culverts to help prevent the build up of aufeis in the culverts during the winter. Geotextile was sewn into 25-ft wide panels and used over the entire alignment to prevent degradation of the tundra mat and provide separation between the fill and the tundra.
