The Stewart-Cassiar Highway, also known as the Dease Lake Highway and the Stikine Highway as well as the Terrace–Kitimat Highway from Kitimat to Terrace, is the northwesternmost highway in the Canadian province of British Columbia. A scenic route through some of the province's most isolated areas, the highway first gained designation as British Columbia Highway 37 in 1975. At that time, its southern terminus was at the community of New Hazelton on the BC Highway 16 (the Yellowhead Highway). In 1979, with the completion of a new bridge, the highway's Yellowhead junction was relocated to a point on Highway 16 just south of the site of Kitwanga. Highway 37 was then extended south to Kitimat in 1986, using a stretch of road that was previously designated Highway 25. At the north end, the highway briefly stretches into Yukon, becoming Yukon Highway 37.
