A watercolour of the Iron Bridge under construction in 1779, by Elias Martin. ... along with a 3D CAD (computer-aided design) model by English Heritage.

Conservation charity English Heritage has launched a crowdfunding campaign as part of a £3.6 million project to save the world’s first iron bridge, featuring a new print from designer Paul Catherall.

The world's first iron structure, and arguably the most important bridge ever built, the Iron Bridge, Shropshire, is a must-see for history and engineering fans alike.
