Inuvik-Tuktoyaktuk Highway

Project Summary

Operating as one of our majority aboriginal-owned partnership companies, Inukshuk Geomatics Inc., Challenger provided survey support for km 52-138 of the Inuvik-Tuktoyaktuk Highway (ITH) project. This road between Inuvik and Tuktoyaktuk on the Arctic Ocean is one of the most technically demanding highway projects to be completed in Canada, with much of the route being constructed over permafrost with little support infrastructure.
