This isn’t the Half Mile Bridge across the Don in Toronto. It;s the Kinzua Sky Walk in Pennsylvania. This old railroad structure continued all the way across the valley however a tornado with a somewhat rusty structure meant half of it came down. With about $4m of fixing it now generates over $11.5m in tourism annually. Its listed as a #1 attraction of TripAdvisor.
Toronto’s Half Mile Bridge contributes Zero tourism dollars to the local economy. Proposals to use the Bridge are, well, actually there are no plans to use the bridge. Metrolinx is sitting on it and nothing will happen for at least the next 25 years.
