Ole Knutsen Singstad (1882 to 1969) was a Norwegian-American civil engineer best known for underwater vehicular tunnels in New York City. Born on a farm in Lensvik, Norway, he trained in Trondheim and emigrated to the United States in 1905. He designed the transverse ventilation system that made long road tunnels workable, first used in the Holland Tunnel, and directed its construction after the deaths of its first two chief engineers. He also designed the Lincoln Tunnel, the Queens-Midtown Tunnel and the Brooklyn-Battery Tunnel, led the Waasland tunnel under the Scheldt in Antwerp, and advanced the immersed tube method with prefabricated sections for the Baltimore Harbor Tunnel. In 1946 he was sidelined when the Triborough Bridge Authority took over the tunnel authority.
