British Columbia Highway 3, officially named the Crowsnest Highway, is an 841-kilometre (523 mi) highway that traverses southern British Columbia, Canada. It runs from the Trans-Canada Highway (Highway 1) at Hope to Crowsnest Pass at the Alberta border and forms the western portion of the interprovincial Crowsnest Highway that runs from Hope to Medicine Hat, Alberta. The highway is considered a Core Route of the National Highway System.

Hope is a district municipality at the confluence of the Fraser and Coquihalla rivers in the province of British Columbia, Canada. Hope is at the eastern end of both the Fraser Valley and the Lower Mainland region, and is at the southern end of the Fraser Canyon. To the east, over the Cascade Mountains, is the Interior region, beginning with the Similkameen Country on the farther side of the Allison Pass in Manning Park. Located 154 kilometres (96 mi) east of Vancouver, Hope is at the southern terminus of the Coquihalla Highway and the western terminus of the Crowsnest Highway, locally known as the Hope-Princeton, where they merge with the Trans-Canada Highway. Hope is at the eastern terminus of Highway 7. As it lies at the eastern end of the Fraser Valley in the windward Cascade foothills, the town gets very high amounts of rain and cloud cover – particularly throughout the autumn and winter.
