Highway 46 began at Highway 28 west of Radway and travelled north to through Boyle.[4] North of Boyle, Highway 46 turned east through Grassland and Atmore, ending in Lac La Biche.[4]
A portion of the gravel road that later became Highway 46 had been constructed by the late 1930s.[5][6] Construction of Highway 63 between Atmore and Fort McMurray began in 1962.[7] In the late-1970s, in conjunction with new highways being constructed between Athabasca and Boyle as well as between Lac La Biche and Cold Lake, the 30 km (19 mi) east-west section between Atmore and Lac La Biche was renumbered to Highway 55.[3] The 89 km (55 mi) north-south section between Radway and Boyle became part of Highway 63, while a 23 km (14 mi) concurrency with Highways 55 & 63 was established between Boyle and Atmore.[3]
