Bridge removed by crane

A Tadano ATF 400G-6 crane helped remove a 34 t bridge spanning France’s Autoroute du Nord in a single lift. 

The bridge – which measured 35 m (114 ft) long, 5 m (16 ft) wide, and 5 m high – was lifted in a single piece in one lift and set down at the rest stop in the construction site area.
