Gardiner Expressway

Gardiner Expressway

The Frederick G. Gardiner Expressway, colloquially referred to as "the Gardiner", is a municipal expressway in the Canadian province of Ontario, connecting downtown Toronto with its western suburbs. Running close to the shore of Lake Ontario, it extends from the junction of Highway 427 and the Queen Elizabeth Way (QEW) in the west to the foot of the Don Valley Parkway (DVP) in the east, just past the mouth of the Don River. East of Dufferin Street, the roadway is elevated, running above Lake Shore Boulevard east of Bathurst Street. Elevated sections east of the Don were demolished and integrated into Lake Shore Boulevard.

The highway is named for the first chair of the now-defunct Metro Council, Frederick G. Gardiner, who championed it, the Don Valley Parkway and Spadina Expressway projects. The six-lane section east of the Humber River was built in segments from 1955 until 1964 by the Metropolitan Toronto government with provincial highway funds. The ten-lane section west of the Humber was formerly part of the QEW provincial highway. The Gardiner Expressway is now wholly owned and operated by the City of Toronto.

When the Gardiner was built, it passed through industrial lands, now mostly converted to residential lands. Extensive repairs became necessary in the early 1990s, and since then the Gardiner has been the subject of several proposals to demolish it or move it underground as part of downtown waterfront revitalization efforts. One elevated section east of the Don River was demolished in 2001, and a current study is underway to demolish that part of the elevated section east of Jarvis Street to the Don.
