This site contains a 3-D computer generated model of Iron Bridge built alongside the river Severn (near Telford and the Ironbridge gorge museums) and completed in 1779. the 3-D model show you how the first iron bridge was built so this site is useful to the historians and the technologists. Note: The graphics need Cosmo Player 2.1 to run which is a free download plug-in available direct from the web page. (It's a big download, about 3.25mb, so expect a delay the first time you look at these 3ds on any computer).
