Tower Bridge

Tower Bridge is a combined bascule and suspension bridge in London, England over the River Thames. It is close to the Tower of London, which gives it its name.

At 21:35 on 30 December 1952, a crowded double-decker London bus (an RT), on route 78 to Dulwich, jumped over the gap when the bridge started to open while it was halfway across.
