Alberta Provincial Highway Network List Former
← Highway 1 → Highway 1X

Alberta Provincial Highway No. 1A is the designation of two alternate routes off the Alberta portion of Trans-Canada Highway 1. However, it is not the only name used for spurs off Highway 1 - Highway 1X is another such designation. Despite these highways being suffixed routes of Highway 1, they are not part of the Trans-Canada Highway network, and are signed with Alberta's provincial primary highway shields instead of the Trans-Canada shields used for Highway 1.^[1]
