winter roads

A winter road is built over land on compacted snow, frozen tundra and bare ground, or on a floating ice cover. Segments of a winter road that cross an expanse of floating ice are also referred to as an ice road or an ice bridge. Conversely, a winter road may be built mostly on floating ice, with occasional land crossing called 'portages' - the Tibbitt to Contwoyto Winter Road is an example.
