Prince Edward Viaduct completed in 1918 is a bridge over Don Valley. Everybody calls this important 494 meters link the 'Bloor Viaduct'.
Architect Edmund Burke displayed great foresight in designing the bridge by including a lower rail deck 50 years before the first subway rolled across it in 1966.
Estimated construction costs were prohibitive ($2,500,000 in 1913) and residents west of the Valley labelled the plans a "bridge to nowhere" because the Danforth area was so sparsely populated.
According to Toronto historian Mike Filey, Prince Edward - later King Eddy the VIII, crossed the bridge, but never even stopped, much less attended a ceremony naming the bridge in his honor. There is always the option renaming it after a Canadian - (Justin Bieber??)
Bloor-Danforth Subway line carries 500,000 people daily! (during a workweek)
