[PAR] [TLE] Holland Tunnel [SEP] The Holland Tunnel is a highway tunnel under the Hudson River between Manhattan in New York City and Jersey City, New Jersey.  Its two tubes carry eastbound and westbound Interstate 78.  In New Jersey, it is also designated NJ 139.  An integral conduit within the New York Metropolitan Area, it opened in 1927 as the first of two vehicular tunnels under the river, the other being the Lincoln Tunnel.  Both are operated by the Port Authority of New York and New Jersey. [PAR] [TLE] Ole Singstad [SEP] 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.
