Tuktoyaktuk Winter Road, an extension of the Dempster Highway, was an ice road on frozen Mackenzie River delta channels and the frozen Arctic Ocean between the Northwest Territories communities of Inuvik and Tuktoyaktuk, in Canada. The road closed permanently on 29 April 2017 at the end of the 2016-2017 winter season.[1] Construction of an all-season highway between Inuvik and Tuktoyaktuk commenced in April 2013;[2][3] it opened on 15 November 2017.[4]
It serviced gas hydrate fields and exploration facilities at Mallik, Aput, and Langley, along with the ice-locked barges Wurmlinger and Arctic Star, which act as bases of operations for ice road crews and exploration personnel. In addition, the road was a key supply line for Tuktoyaktuk and the hamlet of Aklavik.
