Holland Tunnel, Beneath Hudson River between New York & Jersey City, New York, New York County, NY

Significance: The American Society of Civil Engineers (ASCE) and the American Society of Mechanical Engineers (ASME) jointly designated, on May 2, 1984, the Holland Tunnel as an engineering landmark "... in recognition of several engineering firsts: an unprecedented tunnel ventilation system and construction of the longest underwater vehicular tunnel and the largest tube in diameter 29.5-foot diameter twin tubes at the time of completion." (Quoted from ASME/ASCE press release, May 2, 1984). According to the ASME and ASCE, every subsequent vehicular tunnel has used a ventilation system based on the one developed for the Holland Tunnel.
