The Bridge that Spanned the World

The Iron Bridge across the River Severn in Telford, England is two centuries old this year. It remains a monument to the Shropshire iron masters who built it, and a symbol of the Industrial Revolution that was born in the area where the bridge stands. NOVA traces the development of ironmaking and its far-reaching effects on society and the world economy.
