The object of this thesis is to give a detailed description of the method of replacing the old wooden bridge across Boulder Creek by a steel plate girder without interfering with the traffic; also to investigate the strength of the girder in all its parts. The first part of the thesis includes a description of the bridge, and its abutments; the erection of the superstructure, the manner of riveting, and a summary of the costs. The second part is an investigation of the strength of the various parts of the steel work according to Cooper's Specifications for Railroad Bridges (1904 Edition).
