Description |
An Open University film about the use of various forms of iron in the construction of bridges. The shortcomings of stone bridges are explained, and there are shots of the first iron bridge at Coalbrookdale. Developments in the iron and engineering industries lead to the use of wrought iron, and the construction of more ambitious bridges, like those at Conwy castle and over the Menai straits, and ultimately, the Forth Bridge, designed by John Fowler and opened in 1890. |
