Two mile long bridge blown up in controlled explosion

A bridge has been blown up in China to make way for a new longer highway.

Explosives were put along the bridge then set off in a chain.

The Dunyang highway viaduct collapsed after the demolition in Wuhan, Hubei province.

The two mile long bridge is the longest ever to be blown up in China.

It was difficult to destroy safely because it was near homes, wires and gas pipes.
