During winter, the Tibbitt to Contwoyto Winter Road is opened for semi-trailer truck traffic to take supplies from Yellowknife north to various mines located in the Northwest Territories and Nunavut. This ice road is usually open from the end of January through late March or early April, and Yellowknife becomes the dispatch point for the large number of truck drivers that come north to drive on the ice roads. During the 2007 ice road season, several drivers were featured on the History Channel TV series "Ice Road Truckers".
