President, Gandhi Engineering, Inc., New York City, U.S.A. says: "The Verrugas Viaduct was 51.8 miles from Lima and 5,850’ above sea level in the Andes mountains. The wrought iron viaduct was designed, fabricated and shipped by the Baltimore Bridge Company via land and sea to Callao from where it was transported to the site on rail and mules. The viaduct consisted of four Fink truss spans, three of 100’ in length and one 125’ long. The three piers were 146’, 252’, and 179’ in height; and were all 50’ wide. The total length of the viaduct was 575’. The fabricator had planned to frame the spans in the bed of the gorge and lift them bodily into place. However, Leffert L. Buck, the Resident Engineer, devised an ingenious erection scheme, and the viaduct was opened to traffic on January 8, 1873."
