Officially named the
Prince Edward Viaduct, Toronto's Bloor Viaduct was built in 1919 by
Edmund Burke (who also built the famous
CHUM/
CITY Building on Queen West).
The bridge carries traffic, the Bloor-Danforth Subway and the usual cables across the spectacular Don Valley. In ancient times, apparently, the Don River filled the whole valley, although only a trickle alongside the road, Don Valley Parkway, railroad and country club remains (and the guy selling flowers at the base of Pottery Road).
Burke was truly a visionary, in that he foresaw the growth of Toronto, and thoughtfully left two train-sized gaps in the concrete buttresses at each end... and eventually they did carry the trains, over 50 years later (in one of the most vertigo-inducingly spectacular subway rides, ever, quite a feat given all the other marvellous sights on the TTC)
Unfortunately, the bridge is mostly notorious for being the best place in the city to commit suicide off of, to the extent there are free phones to call for counseling on spaced along the bridge. Statistics revealed one depressed Torontonian hurling themselves into the abyss every 22 days, adding to the total of over 400 since the bridge's construction. So, they built a suicide prevention veil to stop this. The suicide veil is a large metal fence-style construct designed to make it impossible for someone to jump over the edge... sort of like a safety net.
