Toronto skyline picture
The Gardiner Expressway in Toronto is the world's longest elevated freeway. If the city follows through with plans to bury this expressway underground, it would no longer hold that distinction. To many Torontonians, it would be good riddance to an eyesore that has long divided the city from the waterfront. To me, it would be the loss of the closest thing the city has to a downtown bridge -- that architectural span that has defined the skyline of such cities as San Francisco and New York City.
