When drivers tried to travel the Mackenzie Valley winter road in the Northwest Territories last March, it was an unpassable highway of muck well before its usual closure date. Four communities were left without vehicle access.

A study of the winter road that leads from Yellowknife to the diamond mines of the Central Arctic predicts it will be unable to carry any heavy loads by the end of the century. Say you park your vehicle on the ice. If you leave it there two or three hours, the vehicle may break throughMixing wood pulp into ice hardens it. The blend was used during the Second World War to create an experimental aircraft carrier.Most recently, Barrette has experimented with what are called “geotextiles” — in this case, a sheet of polypropylene mesh frozen into the road.
