Don Valley Parkway

The Don Valley Parkway (DVP) is a controlled-access six-lane municipal expressway in Toronto connecting the Gardiner Expressway in downtown Toronto with Ontario Highway 401, the Macdonald–Cartier Freeway. North of Highway 401, it continues as Ontario Highway 404. The parkway runs through the parklands of the Don River Valley, after which it is named. The parkway has a maximum speed limit of 90 km/h (56 mph) for its entire length of 15.0 km (9.3 mi). As a municipal road, it is patrolled by the Toronto Police Service.

The parkway was the second expressway to be built by Metropolitan Toronto (Metro). Planning began in 1954, the year of Metro's formation. The first section opened during 1961 and the entire route was completed by the end of 1966. South of Bloor Street, the expressway was constructed over existing roadways. North of Bloor Street, it was built on a new alignment through the valley, requiring the removal of several hills, diversion of the Don River and the clearing of woodland. North of Eglinton Avenue, the expressway follows the former Woodbine Avenue right-of-way north to Highway 401.

The parkway operates well beyond its intended capacity of 60,000 vehicles per day and is known for daily traffic jams; some sections carry an average of 100,000 vehicles a day. Planned as part of a larger expressway network within Toronto, it was one of the few expressways built before the public opposition which cancelled many of the others.
