The Prince Edward Viaduct used to be the second largest suicide structure in the world (just behind the Golden Gate Bridge). To stem the ease of jumping (and thus any chance of photography over the bridge) the city installed these 5 meter high wires which, imho, are effective, since suicide is the lazy way out – if you really want to die unhappy; go through the rest of life like a man!
i really like the angle a lot. i've seen many pictures of the bloor viaduct, but none like this. i think the effect on the lights is cheesey though.
