Dean Bridge, Edinburgh
Built by Thomas Telford to span the Water of Leith in Edinburgh's New Town, where he had worked as a mason in his youth. Four arches support the roadway, each span 90ft, with a rise of 30ft. Telford modified his original design for a three-span bridge when difficulties with the foundations emerged.
To reduce the actual weight of the bridge, which stands 106ft above the water at its highest point, Telford used hollow-wall piers following the technique he had adopted at Pontcysyllte.
Construction by John Gibb of Aberdeen.
