American Bridge Company

In the 1800s, the makings of American Bridge Company were already in motion. In 1874, the Keystone Bridge Company completed the Eads Bridge โ€“ the first steel bridge across the Mississippi River. In 1900, Keystone Bridge Company became part of American Bridge. 

American Bridge is a legendary construction company whose projects include a significant proportion of the worldโ€™s large bridges, marine installations, and other complex structures. Its history, project experience, safety leadership, reputation for integrity and competence, commitment to in-house development of human talent, equipment fleet, and above all, its advanced engineering technology, make the company unique in the entire world.

Our project experience spans thousands of completed projects in locations distributed across all 50 States and 60 foreign countries, making us one of the oldest and most accomplished complex construction firms in the world.

American Bridge Company follows a central strategy delivered through a regional operating structure, designed to effectively pursue, staff, and manage projects in proximity to the work. Each region is led by a team including a regional manager, a regional estimating manager, and a regional director of business development. This allows each region to focus on American Bridgeโ€™s core work types: new bridgesbridge rehabilitation and maintenancecomplex structures, and marine construction. However, each region also has latitude to develop the business within their geographical area that best responds to the needs and opportunities of that area. American Bridge has extensive history and current projects in each of these regions.
