content: This series is comprised of reports, shipping invoices, blueprints, and correspondence created by bridge company employees and engineers concerning bridge construction and maintenance.  It is divided into three subseries based on the three bridges that the collection documents: the Railway Suspension Bridge, the Third Suspension Bridge, and the Lower Arch Bridge.  Due to the span of dates and range of materials associated with the Lower Arch Bridge, this subseries is further separated into three sub-subseries: Construction, Condition and Maintenance, and the Pennsylvania Steel Company.  The Construction subseries contains materials directly related to building the Lower Arch Bridge.  Condition and Maintenance contains publications, reports, and other documents pertaining to the condition of the bridge after its completion.  The third subseries documents the supply of bridge materials for the Lower Arch Bridge by the Pennsylvania Steel Company and includes shipping invoices and blueprints.
