Icefields Parkway
The Icefields Parkway, is a long scenic road that parallels the Continental Divide, traversing the rugged landscape of the Canadian Rockies, travelling through Banff National Park and Jasper National Park. It is named for features such as the Columbia Icefield, visible from the parkway. It links Lake Louise with Jasper to the north. At its southern end, the Icefields Parkway terminates at Highway 1. Highway 1 west leads to Yoho National Park in British Columbia and Highway 1 east to Lake Louise and the Town of Banff. A second parkway, the Bow Valley Parkway also links Lake Louise and the Town of Banff. Known as Highway 1A, this road parallels Highway 1 and, at the midpoint, passes the Castle Mountain junction where Highway 93 south, or the Banff-Windermere Highway, branches southwest into Kootenay National Park in British Columbia. The Icefields Parkway was predated by the Glacier Trail, which opened in 1885 after the Canadian Pacific Railway was completed and brought increased tourist traffic to Banff National Park. In 1931, the federal government commissioned the construction of a single-track road between Lake Louise and Jasper in the Great Depression as a relief project. In order to employ as many people as possible, the road was constructed by hand and employed 600 men. The road was completed in 1940; however, the 1950s saw an increase in automobile use and increased traffic along the parkway. In 1961, a reconstructed paved and modern highway was opened. The parkway is busy in July and August with up to 100,000 vehicles a month. The parkway is mainly two lanes with occasional passing lanes. It minimizes grades and hairpin turns but travellers must look out for wildlife, and vehicles stopped on the shoulder. Snow can be expected at any time of year and extreme weather is common in winter. A Canadian national parks permit is required to travel on the Icefields Parkway; stations near Lake Louise and Jasper enforce the law. Commercial trucks are prohibited. The speed limit is although the limit is reduced at Saskatchewan River Crossing and the Columbia Icefield area. In winter, chains or winter-rated radial tires are required by law and road closures may occur without warning. There is no cell coverage. The Icefields Parkway has long been viewed as one of the bestroad trips in the world and was recently ranked as one of Canada's top road trips by Must Do Canada in 2020.
Just south of Jasper, a short spur of the parkway branches off as Highway 93A, providing access to businesses on the south side of Jasper and providing an alternative route into the community via Hazel Avenue. Another Highway 93A spur farther south is long, is along Highway 93 and provides alternative access to viewpoints and other attractions within Jasper National Park. Highway 93A south of Jasper is narrow and the pavement uneven, with an average limit of. Brush grows up to the side of the highway so animals can be difficult to see.
