The American Bridge Company is a privately held civil engineering firm specializing in the construction and renovation of bridges and other large civil engineering projects, founded in 1900, and headquartered in Coraopolis, Pennsylvania, a suburb of Pittsburgh. The firm has built many bridges in the U.S. and elsewhere, with Historic American Engineering Record this listing (at the Library of Congress) noting at least 81. A partial listing of projects is below. The firm is listed as the builder of a project but may not necessarily be (and usually is not) the designer. In most cases the bridge designer or building architect does not get to select the construction company, he designs it but then bids are let by the owners/developers. The designer and the contractor have to subsequently work together closely to get the job done. American Bridge has also been involved in significant building construction projects such as the Willis Tower, the Empire State Building and the Chrysler Building, as well as in other structural projects such as launch pads and resorts. Significant competitors include Walsh Group, Flatiron Construction, and Skanska USA. Related companies include American Bridge
