Abstract
The album contains a collection of photographs of six Pennsylvania bridges and several railroad works possibly inspected by G. W. Philips in a period from 1900 to 1930. Perhaps the most well-known Pennsylvania bridge is the multi concrete arch Hyner Bridge over the Susquehanna River near Renovo, Pennsylvania. The Hell Gate Bridge over the East River in New York City is an anomaly among the construction photographs in the album as the only New York bridge. The album is an interesting...

Abstract
John Reid, the acknowledged photographer of this picture, was in his lifetime known as a pioneer photographer of the “Iron Horse” (steam locomotives). He introduced the convention of taking the photographs “from a position just ahead of the smoke box” in the late 1850s. This angle is apparent in this photograph as the 4-4-0 steam locomotive positioned on the Harlem Bridge. The bridge is an example of a Post box-truss type developed by Simeon S. Post in 1863. Based on information printed...

Abstract
This manuscript contains three bridge
design class exercises indicating the instructional process to train engineering
students. Specific step-by-step instruction in designing for various railroad bridge
spans, building material specifications, structural loads and stresses to be
considered as presented in the professor’s lecture. The complete process of
calculating the design with comparisons of different conditions, as well as material
available, costs incurred of every aspect of the...

Abstract
A collection of construction photographs of a steel railroad bridge erected on a dry flat plain which eventually became a Mississippi River floodway channel. The channel beneath the bridge elements was dredged after the bridge was constructed. This construction procedure was in reverse of the usual building process. Construction by Bethlehem Steel began in late 1940 and completed in early 1941. The reverse building process was unusual at the time. The bridge is also known as the Wax Lake...
