China pulls down 3.5km viaduct in one stunningly precise blow (video)

A 3.5km-long Zhuan-yang viaduct in the Chinese city of Wuhan has blown up to make place for a wider highway. It also broke the record for the longest concrete bridge ever demolished in China. The road runs from Shanghai to Tibet and is to be replaced by a 6-lane. 

The plan for a perfectly-timed destruction went by without a hitch, as the footage shows. It broke the record for the longest concrete bridge ever successfully demolished in China.

Bomb experts spent weeks poring over blueprints of the Zhuan-yang viaduct in Wuhan, in Heibei province, in a bid to work out how to raze the structure to the ground without leaving even a single concrete slab still standing. The viaduct was surrounded by residential buildings, it runs along 100,000-volt wires and over 30 underground pipelines including the main pipeline transmitting natural gas from west to east China are located beneath it.
