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:
“A young person is a person with nothing to learn
One who already knows that ice does not chill and fire does not burn . . .
It knows it can spend six hours in the sun on its first
day at the beach without ending up a skinless beet,
And it knows it can walk barefoot through the barn
without running a nail in its feet. . . .
Meanwhile psychologists grow rich
Writing that the young are ones’ should not
undermine the self-confidence of which.”
—Ogden Nash (1902–1971)
“My father and mother in 1817 were forty-nine days on the road with their emigrant wagons [from Vermont] to Ohio. More than two days for each hour that I spent in the same journey.”
—Rutherford Birchard Hayes (1822–1893)
