Tacoma Bridge, Washington, United States of America (USA).
Long shot of the opening ceremony of Tacoma bridge. Various shots of the suspension bridge waving with the wind until it finally collapses into the river. Some quite spectacular shots of the bridge being shaken to destruction.
The footage of this event clearly took a long while to reach Britain, for although the issue date was 2 December 1940, the bridge collapse seen here had taken place on 7 November 1940.
The vibration and swinging of the bridge seen here is called "aeroelastic flutter". The swinging famously earned the bridge the nickname "Galloping Gertie".
Here's an original newspaper report about the collapse.........
