Queen Street Viaduct, Steel truss bridge over the Don River in Toronto, Canada

The Queen Street Viaduct is a steel truss bridge in Toronto that crosses the Don River, carrying four lanes of road traffic and two streetcar tracks. Separate pedestrian walkways run along both sides of the bridge, keeping foot traffic apart from vehicles and streetcars.

The bridge was built in 1911 by the Cleveland Bridge and Engineering Company, replacing a wooden structure that had stood since the early 1800s. The shift from wood to steel reflected Toronto's move toward a modern city infrastructure during that period.

The 1996 artwork by Eldon Garnet spans three sites. On the bridge's western side, large letters over the road read "this river I step in is not the river I stand in", a phrase from Heraclitus. A clock there stopped working, and its mechanism and hands were removed in 2010. Words are also set into the pavement at Broadview Avenue and Queen Street, with four metal banners at Queen and De Grassi Street.

The bridge sits on a busy stretch of Queen Street, so pedestrians should use the dedicated walkways on either side to avoid traffic. A stop at the railing gives a clear view down to the Don River below.

The bridge's public art by Eldon Garnet, added in 1996, is one part of a three-site piece. The other parts are words set into the pavement at Broadview Avenue and Queen Street, and four metal "banners" at Queen and De Grassi Street. The clock on the west side stopped working, and its mechanism and hands were removed in 2010.
