Gardiner Expressway

The Frederick G. Gardiner Expressway, commonly known as the Gardiner Expressway or simply the Gardiner, is a partially at grade and elevated municipal expressway in Toronto, Ontario, Canada. Running close to the shore of Lake Ontario, it extends from the foot of the Don Valley Parkway (DVP) in the east, just past the mouth of the Don River, to the junction of Highway 427 and the Queen Elizabeth Way (QEW) in the west, for a total length of 18.0 kilometres (11.2 mi).

Often described as "an out-of-date, crumbling and frequently traffic-jammed freeway", the Gardiner is now the focus of a major rehabilitation project that is expected to last at least until 2030.

A section east of the Don River was demolished in 2001, while in 2018, the off-ramp to York/Bay/Yonge Streets was replaced by an off-ramp to Lower Simcoe Street, and the eastern terminus to Lake Shore Boulevard was demolished the following year.
