Prince Edward Viaduct, Multi-level bridge in Don Valley, Toronto, Canada

The Prince Edward Viaduct is a three-hinged concrete-steel arch bridge spanning 494 metres across the Don Valley, 40 metres above the valley floor, linking Bloor Street East with Danforth Avenue. Its deck of transverse beams and I-girders rests on column supports that transfer loads to steel trusses within the arches, supplied by Dominion Bridge Company. The roadway carries five lanes and two bicycle lanes, with a subway level below.

Toronto held referendums on the crossing every year from 1910 to 1913, rejecting it by 59 votes in 1912 and approving it by 9,236 in 1913; the projected cost rose from CA$759,000 to CA$2.5 million. Designed by Edmund W. Burke, it was completed in 1918 at a final cost of CA$2,480,349.05 and named for Prince Edward, Prince of Wales. Its lower deck, added for a future transit line at controversial expense, carried the Bloor–Danforth subway from 1966.

The bridge appears in the 2004 film Resident Evil: Apocalypse under the name Ravens Gate Bridge, serving as a central location in the movie.

Cyclists use dedicated paths on both sides, while pedestrians walk along the full length of the crossing. Access points appear at multiple entrances along Bloor Street and Danforth Avenue.

A metal barrier made of thousands of vertical rods runs along the entire span and forms a continuous transparent wall. This installation changes the appearance of the structure especially at night through shifting light reflections.
