The Stewart-Cassiar Highway, also known as the Dease Lake Highway and the Stikine Highway, is road mostly in northwestern British Columbia, Canada. It runs from Kitwanga, British Columbia to Watson Lake, Yukon and serves as an alternate access to Alaska.
The Stewart-Cassiar Highway, signed as Highway 37, is a 725 km (450 mi) long road that runs from the Yellowhead Highway at Kitwanga, British Columbia to the Alaska Highway near Watson Lake, Yukon. Taking this route as opposed to the entire Alaska Highway can save about 210 km (130 mi) for travellers coming from southern British Columbia and the Pacific Northwest of the contiguous United States. Almost all of the route is in British Columbia, with exception of the northernmost 3.4 km (2.1 mi) which is located in the Yukon. Highway 37 continues southwest from Kitwanga to Terrace and Kitimat.
The Cassiar Highway was completed in 1972, and is asphalt-surfaced with the exception of a short gravel break through the Stikine River valley. The highway passes through hilly and mountainous, mostly wooded wilderness region where services are found in sparsely populated communities that are far from each other.

The Cassiar Highway is very isolated, with a few, small populated areas along the highway so plan your stops for fuel, food and breaks before the start of your trip. The highway is asphalt-surfaced with the exception of a few short gravel breaks and is generally narrower than most 2-lane highways, with little or no shoulder, and the centerline and edge line markings may be missing along some northern sections of the highway; most bridges are a single lane. Drive with your headlights on at all times. Also watch for logging and freight trucks that travel the route 24 hours a day. Internet and cell phone connections is available in Stewart, Dease Lake and Watson Lake; however, do not expect coverage over the entire route.
Grizzly and black bear, caribou, moose, fox and many other species of wildlife can be found on and along the highway. In the late spring and early summer, adults and their young may be crossing the road to find new habitat. When viewing wildlife, please park your vehicle in a safe location and make certain you are not blocking other traffic; admire wildlife from the safety of your vehicle.
Continue north to Whitehorse and points beyond along the Alaska Highway.
