Summary(Plain Language Summary, not published)
Northwest Territories Highway 10 (140-km long), known as the Inuvik to Tuktoyaktuk Highway (ITH), traverses the Anderson Plain and Tuktoyaktuk Coastlands between Inuvik and Tuktoyaktuk over continuous permafrost. Construction began in winter 2014 following the completion of long-term environmental, socioeconomic, and engineering studies. Terrain suitability for the ITH was assessed, in part, through the analysis of sediment cores from a series of geotechnical boreholes drilled along the proposed route, and at anticipated bridge piling locations, prior to construction in 2013. Additional boreholes were drilled in winter 2017 along the ITH embankment and at undisturbed 'Sentinel' sites that represent distinct regional terrain types. The ITH opened in November 2017. This report compiles geotechnical and supporting data obtained through these projects and describes spatial variation in substrate characteristics.
