Arcing like a steel rainbow 486 feet above the Snake River since 1976, the Perrine is the only bridge in the United States where you can walk halfway across and jump off — legally.

One mile to the east, you can still see the dirt ramp Evel Knievel used in his ill-fated 1974 attempt to jump the Snake River canyon (free). — Photo by Newscom
