Tense moment during the destruction of a bridge

A construction site in China attracts curious onlookers who come to film the demolition of an old bridge. Workers use a giant jackhammer to attack the structure. Eventually, the concrete gives way with a jolt. A huge cement block breaks away and falls straight into the river below. The noise is loud, and the sudden movement startles those who were too close. Spectators quickly retreat, some visibly frightened by the power of the collapse.
