History
The company was established in 1946 by renowned bridge engineer Othmar Ammann and structural pioneer Charles S. Whitney. Early in its history, the firm partnered with architect Eero Saarinen on groundbreaking thin-shell concrete designs such as Kresge Auditorium (1955), the TWA Flight Center (1962), and the main terminal at Dulles International Airport (1962).
Ammann & Whitney broadened its reach internationally, specializing in long-span suspension bridges as well as various steel, concrete, masonry, and timber structures designed for vehicular, pedestrian, and rail use. Among their distinguished bridge projects are the Delaware Memorial Bridge, Walt Whitman Bridge, General Belgrano Bridge in Argentina, Throgs Neck Bridge, and the renowned Verrazano-Narrows Bridge.
After merging with Louis Berger in 2016, Ammann & Whitney became the long-span bridge division within Berger.
The firm maintained multiple offices along the U.S. East Coast, with headquarters located in New York City and additional branches in Boston, MA; Philadelphia, PA; Pittsburgh, PA; Richmond, VA; Miami, FL; and Washington, D.C..
