Description

Sample of early lime concrete removed from the bottom of the road carriageway on Dean Bridge Edinburgh on 18 March 1973. The concrete layer prevented water penetration into the hollow spandrels beneath.

John and Alexander Gibb was the contractor for bridge construction.

It is said of John Gibb: “Apparently John Gibb, although in other circumstances he could display an irascible temper, was also well liked by his workmen. When building the Dean Bridge he had an elevated perch made from which he could survey their progress and bellow criticisms through a sort of megaphone. On occasions he descended amongst them ‘to exchange blows, banter and snuff’ to the delight of all.” (Biographical Dictionary of Civil Engineers Volume 1 1500 – 1830, Edited by Professor Sir Alec Skempton, Published by ICE Thomas Telford, London, 2002).
