Highway 15 (BC 15), known locally as the Pacific Highway, is a 20.99-kilometre-long (13.04 mi) north–south highway primarily located in the City of Surrey, British Columbia. The southern terminus is with Interstate 5 (I-5) near Blaine, Washington, as State Route 543 (SR 543). SR 543 is a 1.75-kilometre-long (1.09 mi) connector between I-5 and the Canada–US border, linking with BC 15. Over 3,000 trucks per day pass through the border crossing along SR 543 and BC 15, because the Peace Arch border crossing does not allow commercial trucks.
