First completed in 1960 as a gravel and dirt road, the highway is now paved and realigned after years of work concluded in 2006. Access to Yellowknife prior to the opening of the Yellowknife Highway was possible only by airplane, winter road, or boat across Great Slave Lake.The highway also connects with Behchokǫ̀ (formerly Rae-Edzo) and Fort Providence. From Yellowknife, Highway 4 extends a further {{convert|70|km|abbr=on}} east, also providing access to the seasonal winter roads used by commercial trucking for mine resupply.Crossing the Mackenzie River (just south of Fort Providence) between 1960 and November 2012 required a ferry service (May–January) and ice bridge (December to March). Transportation was interrupted in the spring for approximately five weeks when the ice bridge became unsafe but ice conditions prevented safe ferry operations. The ferry-vessel Johnny Berens served from 1961 to 1972, and the MV Merv Hardie served from 1972 to 2012.The Deh Cho Bridge opened on November 30, 2012, and replaced the ferry/ice bridge.NEWS,weblink Deh Cho Bridge to open Nov. 30, CBC News, November 6, 2012, November 8, 2012, Trucks pay tolls on northbound crossings, with pre-registered trucks using an electronic device being charged automatically.
