Spokane Street Bridge
Posted April 13, 2011, by Robert Thompson (rkt [dot] engineering [at] gmail [dot] com)

From Wikipedia:

"Each 7,500-short-ton (6,800 t) leaf of the bridge floats on a 100-inch (2.5 m) steel barrel in hydraulic oil. It is claimed[1] to be the only bridge of its type in the world and it has received several awards for its innovation, including the Outstanding Engineering Achievement Award of the American Society of Civil Engineers in 1992." Very unique indeed!
