Check out Sandro Dias skating what has to be the sketchiest halfpipe setup in the history of the world. The Ponte Governador Orestes Quércia bridge spans 2,165ft over the Tietê River in São Paulo. It stands at over 180ft and has
an architectural feature that works as a perfectly nestled halfpipe (albeit wildly dangerous) between two of its towers. Louco!
