Ice Road
Ice roads (ice crossings, ice bridges) are frozen, human-made structures on the surface of bays, rivers, lakes, or seas in the far north. They link dry land, frozen waterways, portages and winter roads, and are usually remade each winter. Ice roads allow temporary transport to areas with no permanent road access. Seen in isolated regions of northern Canada, Alaska's Bush, northern Michigan, northern Scandinavia and Russia, they reduce the cost of materials that otherwise would ship as expensive air freight, and they allow movement of large or heavy objects for which air freight is impractical.
Ice roads differ from winter roads in that they are built primarily across frozen waterways. Ice roads may be winter substitutes for summer ferry service. Ferry service and an ice crossing may operate yearly at the same time for several weeks.
An alternative meaning of ice bridge is a natural ice road or a structure formed during glaciation. These were used in prehistoric migration.

Famous quotes containing the words ice and/or road:
“We may prepare food for our children, chauffeur them around, take them to the movies, buy them toys and ice cream, but nothing registers as deeply as a simple squeeze, cuddle, or pat on the back. There is no greater reassurance of their lovability and worth than to be affectionately touched and held.”
—Stephanie Martson (20th century)
“[T]he temple through which alone lies the road to that of Liberty.”
—James Madison (1751–1836)
