Britain's Greatest Bridges

The last of the truly great Victorian engineering triumphs, the Forth Rail Bridge has grown to symbolise Scotland. However, as Rob discovers, this incredible engineering achievement was born from tragedy.

Engineer Rob Bell uncovers the extraordinary story behind Tower Bridge, revealing how it was funded, how its design was revolutionary for the time, and how it is lucky it is to still be standing.

Rob Bell tells the story behind Brunel's famous bridge over the picturesque Avon gorge at Bristol and discovers that some people question whether the great man's `Darling' was entirely the product of his own inspiration.

In May 1970, four boys set light to Robert Stephenson's famous Britannia Bridge across the Menai Strait, destroying one of the most important advances in structural engineering of the last 200 years.

Built partly as a lifeline to keep shipbuilders employed and their skills alive during the dark days of the 1920s recession, the Tyne Bridge is not just an icon to Geordies - many believe that it was the inspiration for the Sydney Harbour Bridge.

For 17 years from 1981 to 1998, the Humber Bridge was the longest single-span suspension bridge in the world, and many consider it to be Britain's most beautiful. Rob Bell discovers the facts about its ground-breaking construction.
