The highway is a component of Canada's National Highway System. Between Highway 28A near Gibbons and the intersection with Highway 63 near Radway, it forms part of the Edmonton-Fort McMurray corridor and is designated as a core route. For the remainder of the route from Radway to the eastern end at Cold Lake, it is designated as a feeder route.[4]
History
Highway 28 was built in 1961, connecting Alberta's Lakeland to Edmonton by gravel road for the first time. Construction of the highway required splitting Mann Lake in two, creating Upper and Lower Mann Lake.[5]
Prior to 2006, Highway 28 ran through St. Paul. A 46 km (29 mi) section of the current highway between Ashmont and Hoselaw was formerly designated as Highway 28A, a bypass of St. Paul. As part of an effort to simplify highway route numbering in the region, this section was re-signed as Highway 28 in 2006 forming a more contiguous route between Edmonton and Cold Lake, while Highway 28 through St. Paul was re-signed as Highway 29.[6]
Highway 28X
Highway 28X was a 14-kilometre (9 mi) spur route of Highway 28. It began at Highway 28, approximately 10 kilometres (6 mi) south of Cold Lake, and travelled to the Saskatchewan boundary where it continued east as Saskatchewan Highway 55.[7] In c. 1977, Highway 28X was part of a number of highways which were renumbered when Alberta Highway 55 was established between Athabasca and the Saskatchewan border.[7][8]
Future
Alberta Transportation ultimately intends to upgrade the entire Edmonton-Fort McMurray corridor to a divided highway, which would include twinning of Highway 28 from Highway 28A to Highway 63.[9]

Alberta Transportation plans to twin Highway 28 and Highway 28A, running all the way into Edmonton. Functional alignment studies have been completed on all of 28A, and on Highway 28 between Gibbons and Highway 63 as well as from Edmonton to Highway 642, with the last remaining section expected soon.
