The Mackenzie Highway is the longest in the Northwest Territories. It begins at the Northwest Territory and Alberta border and ends at Wrigley, Northwest Territory. It is approximately 690 kilometers or 429 miles long. About 280 kilometers are paved while the rest of the highway is covered with gravel (Government of Northwest Territories, n.d.). The construction of this highway was ongoing between the 1940s and 1970s. In 1945, the Canadian federal government and the government of Alberta signed an agreement to build an all-weather road that would replace the existing Caterpillar tractor trails from Grimshaw to the Great Slave Lake of Hay River (Prince of Wales Northern Heritage Center, n.d.). As time passed and focus shifted to fossil fuel collection, the motivation behind further construction of the Mackenzie Highway was in “anticipation of a major oil pipeline development along the Mackenzie River valley” (Pomeroy, 1985). The intended use of the highway was to enable the pipeline developers to haul construction materials throughout the area. During its construction, many chiefs of the Indian Brotherhood opposed the completion of the Mackenzie Highway. There was additional opposition voiced from the people of Wrigley who also did not support further construction of the Mackenzie Highway (Cox, 1975).
