The American Bridge Company is a privately held civil engineering firm that specializes in building and renovating bridges and other large civil engineering projects. Founded in 1900, the company is headquartered in Coraopolis, Pennsylvania, a suburb of Pittsburgh.
The firm has built many bridges in the U.S. and elsewhere; the Historic American Engineering Record at the Library of Congress notes at least 81. Among its other projects, American Bridge has built or helped build the Willis Tower, the Empire State Building, the Chrysler Building, launch pads, resorts, and more. During World War II, American Bridge produced landing ships (LSTs) for the United States Navy.
Related companies include American Bridge Holding Company and American Bridge Manufacturing Company, both also headquartered in Coraopolis.
American Bridge Company was founded in April 1900, through the JP Morgan-led consolidation of 28 of the largest U.S. steel fabricators and constructors. The company’s roots extend to the late 1860s, when one of the consolidated firms, Keystone Bridge Company, built the Eads Bridge, the first steel bridge over the Mississippi River, at St. Louis and still in use. In 1902, the company became a subsidiary of United States Steel as part of the Steel Trust consolidation.
The company pioneered the use of steel as a construction material; developing the means and methods for fabrication and construction that allowed it to be widely used in buildings, bridges, vessels, and other plate applications. As a result, and due to its deep financial resources, American Bridge has performed work across the nation and the world since its founding.
Some of American Bridge’s most notable projects are more a testament to construction engineering know how and management abilities than to its historical strength in steel construction.
The company went private in 1987.
The town of Ambridge, Pennsylvania was an American Bridge Company town (thus the name "Ambridge"), and is near their current headquarters of Coraopolis, Pennsylvania. Both municipalities are on the Ohio River near Pittsburgh, with access to many steel suppliers, as well as to waterborne and rail transport, to allow shipment of components and subassemblies.

- Built bottom framework for the unique, modular room units for Walt Disney Company at the Contemporary Resort in Walt Disney World (1971).
- The firm listed as the builder of a project is usually 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 work together closely to get the job done.
