The Canadian province of British Columbia has a system of numbered highways that travel between various cities and regions with onward connections to neighboring provinces and U.S. states. The numbering scheme, announced in March 1940, includes route numbers that reflect United States Numbered Highways that continue south of the Canada–United States border. Highway 1 is numbered in accordance with other routes on the Trans-Canada Highway system. Major routes East-west The Trans-Canada Highway (Highway 1) runs from Victoria to Nanaimo on Vancouver Island. Then, after a ferry ride to the mainland, it continues from Horseshoe Bay, through the Vancouver area, Abbotsford, Hope, Kamloops, Salmon Arm, and Revelstoke to Kicking Horse Pass on the BC/Alberta border. This is the major east-west route in the province. The Crowsnest Highway (Highway 3) runs from Hope, then through Osoyoos, Castlegar, Cranbrook, right to Crowsnest Pass on the BC/Alberta border. This is a southern alternate route to the Trans-Canada, and runs very close to the Canada–US border. The Yellowhead/Trans-Canada Highway (Highway 16) starts on Haida Gwaii. After a ferry ride to the mainland, it runs from Prince Rupert through Smithers and Prince George, and then meets the Alberta border at Yellowhead Pass. The Lougheed Highway (Highway 7) is a major alternate route that runs from Vancouver to Hope, north of the Fraser River. The Okanagan Connector (Highway 97C) is a short but major route that connects the Okanagan Valley to the Coquihalla Highway (Highway 5) at Merritt. 97C branches off Highway 97 at Peachland, about midway between Penticton and Kelowna. North-south The Island Highway (Highway 19) is an extension of Highway 1 on Vancouver Island. It runs from Nanaimo and provides access to all points northbound on Vancouver Island, including Parksville, Courtenay, Comox, Campbell River, and Port Hardy. The Patricia Bay Highway (Highway 17) starts in Victoria and heads northbound through Saanich to the Swartz Bay ferry terminal. Recently, there was a gap between the segments of Highway 17 (now filled in with the SFPR), as the Mainland portion was designated as Highway 17A. The new South Fraser Perimeter Road has been named as Highway 17, and presently is open in Delta and Surrey between Highway 17a and Highway 15. Highway 99 starts as an extension of Interstate 5 at the Canada–US border in Surrey as a freeway until entering the city of Vancouver. There it becomes a series of various heavily signalized major city core
