About Ole Singstad
- 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 immersed 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.
