Alberta Provincial Highway No. 28A, commonly referred to as Highway 28A, is an highway in Alberta, Canada that connects Highway 15 in northeast Edmonton to Highway 28 near Gibbons. It is numbered 17 Street NE within Edmonton and forms an alternate route to Highway 28 into the city from the north. As the southernmost component of the Edmonton–Fort McMurray corridor, the highway is designated as a core route of Canada's National Highway System for its entire length. Highway 28A began as a gravel road in the 1930s, formerly designated as Highway 37 which it now intersects at the north Edmonton city limit. Alberta Transportation has plans to upgrade Highways 28 and 28A to a divided highway, with long term plans for a freeway between Edmonton and Fort McMurray. Route description Like most rural two-lane highways in Alberta, Highway 28A is not a controlled-access highway, as numerous driveways and local roads intersect it at-grade. Nevertheless, it forms part of the Edmonton-Fort McMurray corridor and is designated as a core route of the National Highway System. The highway begins at an intersection in northeast Edmonton where it splits to the north from Manning Drive (Highway 15) near 227 Avenue. As 17 Street NE, the two-lane highway proceeds through rural residential and agricultural lands north of Edmonton for approximately to Highway 37, crossing into Sturgeon County. It continues north to the town of Gibbons in which it intersects 50 Avenue and Highway 643 (53 Avenue), approximately north of downtown Edmonton. A bridge carries a branch of the Canadian National Railway over the highway before the road crosses the Sturgeon River on a culvert. While crossing the river, the road briefly widens to a divided highway then immediately terminates at a trumpet interchange with Highway 28. History Highway 28A had been in place as a gravel road since at least 1940, then signed as Highway 37 running from Highway 15 to north of Gibbons. At this time, Highway 28 terminated near Bon Accord and did not connect to present day Highway 28A. A route from Mundare to Cold Lake via Brosseau and St. Paul had already been built by 1930, which later comprised portions of Highway 28 by the mid-1950s. The culvert over the Sturgeon River was built in 1970. The railway overpass in Gibbons was constructed in 1973, followed by the Highway 28 interchange in 1974. Another section formerly existed between Ashmont and
