Many of us whined about the Pan Am/Parapan Am Games, but there were a few upsides to the summer event, like the the numerous legacy project we'll get to enjoy for years to come. While the Toronto Sign in an obvious example, you might not be aware of some of the other ones. Take the BMX Supercross track at Centennial Park, for instance.

The online architecture and design magazine designboom calls the track "an object in a landscape and a landscape in its own right."

The striking concrete and steel structure, designed by Toronto-based firm Kleinfeldt Mychajlowycz Architects Inc., is the only track in Canada certified by the Union Cycliste Internationale (UCI).

As Toronto's Designlines magazine notes, it includes two start ramps - at 5 and 10 metres each - a 517 metre dirt road and a complex underground drainage system; after it rains, the track can dry within half an hour.
