Alberta Highway 63 3.52

Alberta Provincial Highway No. 63, commonly referred to as Highway 63, is a 434km highway in northern Alberta, Canada that connects the Athabasca oil sands and Fort McMurray to Edmonton via Highway 28. It begins as a two-lane road near the hamlet of Radway where it splits from Highway 28, running north through aspen parkland and farmland of north central Alberta. North of Boyle, it curves east to pass through the hamlet of Grassland and becomes divided west of Atmore where it again turns north, this time through heavy boreal forest and muskeg, particularly beyond Wandering River. Traffic levels significantly increase as Highway 63 bends through Fort McMurray, crossing the Athabasca River before connecting the city to the Syncrude and Suncor Energy plants further north. It ends approximately beyond a second crossing of the Athabasca River northeast of Fort MacKay.The southern segment of Highway 63 from Radway to Atmore was built before the mid-1950s and numbered as Highway 46 until the 1970s. Construction north of Atmore on the first road connecting Fort McMurray to the rest of the Alberta highway system began in 1962. Upgrades in the following decades saw the two-lane highway widened and improved with the addition of passing lanes, and extended to its present terminus northeast of Fort MacKay. Since 2004, the highway has formed the majority of the National Highway System core route between Fort McMurray and Edmonton, and in 2016 played a key role in the evacuation of over 80,000 people from Fort McMurray and the surrounding areas during a highly destructive wildfire.
