This is a bridge in Twin Falls, ID. It spans the beautiful Snake River Canyon.
"Twin Falls became the center of national attention in September 1974 thanks to an attempt by Evel Knievel to jump the Snake River Canyon in a specially-modified rocket cycle. Watched by millions on television, the attempt ultimately failed due to high winds and a premature deployment of Knievel's parachute. The foundation of the launch ramp, which lies on private land, can still be seen." Wikipedia
