Ole Knutsen Singstad (June 29, 1882 – December 8, 1969) was a Norwegian-American civil engineer who innovated the ventilation system for the Holland Tunnel (which subsequently became commonly used in other automotive tunnels) and advanced the use of the "Sunk-tube" method of underwater vehicular tunnel building, a system of constructing the tunnels with prefabricated sections.
By 1950, Singstad had designed and overseen the construction of more underwater tunnels than all other engineers combined.
Ole Singstad was born at Singstad farm in Lensvik (now Agdenes) in Sør-Trøndelag, Norway. He was the seventh of nine children born to Knut Jacobsen Singstad (17 Mai 1831- 24 Nov 1906) and Anne Mikkelsd Auset Singstad (10 Jul 1843-30 Apr 1947).
In 1898, Singstad went to Ålesund to study grammar school. Later, his sister Marie, a midwife, encouraged Singstad to further his education. He studied at the Trondheim Technical School from 1901–1905, today Norwegian University of Science and Technology, where he was chairman of the student body. In 1905, he emigrated to the United States. He became a U.S. citizen in 1911.
Ole Singstad first worked for the Central Railroad of New Jersey. In 1907, he moved to Norfolk, Virginia, where he worked on railroads and bridges for the Virginian Railway. He returned to New York City and worked at the Hudson and Manhattan Railroad, designing tunnels under the Hudson River in 1909-1910, and later spent seven years in charge of work on subways and rail tunnels in Manhattan, Brooklyn, and under the East River. During this time he worked with Clifford Holland for the New York Public Service Commission of the first district of New York.
