British Columbia Highway 5

Highway 5 is a 543-kilometre (337 mi) north–south route in southern British Columbia, Canada. Highway 5 connects the southern Trans-Canada route (Highway 1) with the northern Trans-Canada/Yellowhead route (Highway 16), providing the shortest land connection between Vancouver, British Columbia, and Edmonton, Alberta. Despite the entire route being signed as part of the Yellowhead Highway, the portion of Highway 5 south of Kamloops is also known as the Coquihalla Highway, while the northern portion is known as the Southern Yellowhead Highway. The Coquihalla section was a toll road until 2008.

Although the Yellowhead Highway system is considered part of the Trans-Canada Highway, Highway 5 is not represented with a Trans-Canada marker. Regardless, Highway 5 is designated as a core route of Canada's National Highway System (NHS).
