The world's first large iron structure was the Iron Bridge, near Telford in Shropshire. Built in 1779 The Iron Bridge's builders used the technology that they knew. They joined the sections of the bridge with woodworking joints. Here is a dovetail... ... and here, a through housing. Notice how a piece of  the iron has cracked away - showing how cast iron is brittle. Another of the Iron Bridge's joints. This one is complete but shows a crack. Triangles are very stong and cannot be deformed. Here the strength of triangles is used to in scaffolding to support the wall of a derelict building.
