J. E. Greiner Company


J. E. Greiner Company was a Baltimore, Maryland-based civil engineering firm specializing in bridge design. The firm was founded in 1908 by former Baltimore and Ohio Railroad bridge engineer John Edwin Greiner and led by Greiner and his associate Hershel Heathcote Allen. The firm was later known as Greiner Engineering and opened a second office in Chicago, apparently in connection with its work on the Calumet Skyway. In 1995, the firm was acquired by URS Corporation, now part of AECOM.
The firm designed numerous notable bridges and also prepared transportation planning studies, the first of which was Maryland's Primary Bridge Program for the Maryland State Roads Commission. Later studies included Transportation Plans for Washington and Expressway System for Metropolitan Providence, both with De Leuw, Cather & Company.
