Inuvik Tuktoyaktuk Highway

Tetra Tech Canada Inc. and Stantec

Inuvik to Tuktoyaktuk, Northwest Territories  


The Inuvik Tuktoyaktuk Highway (ITH) is the first Canadian highway constructed on continuous permafrost. Tetra Tech and Stantec were instrumental in all phases of the project from initial planning to construction completion. Building a road on sensitive permafrost terrain, in a remote location, posed unique challenges including seasonal constraints, scarcity of materials along the project corridor to construct road embankment, and the constructability of elements in winter conditions. Opened in November 2017, this long-anticipated road will provide essential services, reduce the cost of living, and provide a year-round, physical connection to the rest of Canada. The all-season road immediately benefits the region by eliminating the need for a seasonal winter ice road to be constructed each year. It will also provide employment opportunities through resource development and tourism along the scenic highway and create economic opportunities.
