Madigan-Hyland was an American engineering firm active in the New York City area, named for founders Michael J.

They often worked in concert with architects, other engineers and specialty consultants to complete large and complex urban infrastructure projects.

Madigan (1894-1981) was a Danbury, Connecticut native who worked his way up in the construction industry without formal education and who did not complete high school.

The two met in 1927 and formed the firm shortly after, with Madigan providing business experience and New York City connections, complemented by Hyland's professional design expertise.

Distinguished employees of the firm included Emil Praeger, a notable engineer and designer in his own right.
