A dramatic video has emerged from China of the moment a long overpass was demolished using huge quantities of explosives.<br /><br />The footage, captured last Friday in Fujian province, shows the simultaneous detonations destroying the structure while colourful 'marker' charges go off in the middle. <br /><br />The successful demolition of the 5475.5 metre long bridge in just over 4 seconds reportedly makes this the largest in China's history.
