The demands in the layout of the interstate road no. 70, in Ohio, USA, have made it essential to build two twin bridges, which run over the Pennsylvania railway. Construction operations were hindered by the poor soil conditions and by a number of technical factors connected with traffic. This forced the engineers to seek a more rational and easy construction procedure, which would offer a larger margin of safety, in the face of any unexpected events that might arise, once the bridges were in service. In spite of this, The American Institute of Steel Construction declared that the two bridges were the most beautiful work of its type openend to traffic in the United States, in 1965.
