Ice roads are temporary Highway s formed by using frozen rivers and lake surfaces. They facilitate transportation to and from communities without permanent roads, and are commonly seen in isolated regions in Canada 's north and Alaska's Bush. Ice roads have a crucial role in enabling goods to be brought into communities without permanent road access. In many of these communities, Air Transportation is used at other times of the year to bring in goods including food and supplies, but this can be prohibitively costly for bulky goods such as building supplies and heavy equipment. In general, these roads are built in areas where construction of year-round roads is expensive due to many river crossings, and the presence of boggy Muskeg land. When frozen in winter, these obstacles are easier to cross. In the case of ice roads such as the stretch from Inuvik and Tuktoyaktuk , Northwest Territories , Canada provides an almost level driving surface with few detours several months of the year. Depending on the region, ice roads last anywhere from a few weeks to several months before they become impassable. The roads are normally the domain of large Truck s, although cars are occasionally seen. SEE ALSO
