CSX - Radnor Cutoff Bridge

In the Engineering Record of August 30, 1913, page 244, Vol. 28, N°9, was published a short article, illustrated with a photograph, on this bridge. Here is a complete copy ot this article: "The Cumberland River Bridge of the Louisville & Nashville Railroad is approximately 3000 ft. long. including a viaduct approach at each end, one 300' and three 200' throughtruss river spans and three 135' deck truss spans, all of which have riveted connections except the pin connected 300' span . The substructure is enterely of concrete, of which there about 1700 yd. which were built in cofferdams of interlocking steel sheet piling, under an average head of about 16' of water. All foundations were carried down to bed rock to a depth of 130' below base of rail. In three of the cofferdams considerabme difficulty was experienced from encountering open conduits leading to the city waterwork pumping station, close to one end of the bridge. The concrete was mixed in a plant on each bank of the river and was carried by hauling engines to the different piers. All of the truss spans are erected on falsework built with an overhead traveling stiffleg derrick. It is expected that the erection will be completed this fall. The steel superstructure was fabricated by the American Bridge C° and erected by the Foster-Creighton-Gould C°, of Nashville, Tenn., wich has also constructed the substructure ."
