Leaside Bridge, Road bridge in Toronto, Canada

The Leaside Bridge is a road structure spanning the Don River with six traffic lanes that connects the neighborhoods of Leaside and Thorncliffe Park. The truss design includes dedicated bike lanes and sidewalks on both sides to serve vehicles, cyclists, and pedestrians.

Sod was turned in December 1926 and construction began in January 1927 under engineer Frank Barber. The bridge opened on October 29, 1927, as the Confederation Bridge, marking the 60th anniversary of Confederation. It was widened to six lanes between September 1968 and February 1969, and restored from 2004 to 2006.

The original 1927 handrail was a tiled mosaic designed by New York architect Claude Bragdon, with tiles supplied by the Italian Mosaic and Tile Company. It was replaced by a plain concrete barrier and tubular railing during the 1968–69 widening, then restored between 2004 and 2006 to Bragdon's design.

The bridge is accessible daily for vehicles and active travelers, with clear routes for all user types. Expect to share space with other users, especially during peak times when traffic and cyclist flow increases.

The bridge rises about 45 meters above the Don River Valley, making it one of the highest crossing points in Toronto's transportation network. This height creates views into the valley below and makes the crossing spatially noticeable during the journey.
