First Edition of this superbly illustrated “survey of the iron bridges erected in the wake of the Britannia Tubular Bridge exploiting the increased knowledge of the material and its behaviour resulting from that monumental structure. Humber’s book is made up of a series of plates, each fully described, illustrating examples of all kinds of structures including aqueducts, viaducts and road bridges. A lengthy section is devoted to the Crumlin Viaduct (prototype for many bridges erected overseas), newly opened and built with Warren & Kennard’s patent triangular girder. Other structures include Joseph Cubitt’s bridges on the Great Northern Railway, a splendid tubular girder bridge on the Midland Great Western Railway in Ireland designed by Hemans and constructed by Fairbairn & Sons, Rendel’s Sursuttee Bridge on the East India Railway, Thomas Page’s Chelsea Bridge, and a final section on iron girders used for fire-proof floors.”
