Holland Tunnel Turns 80

This week marked the 80th anniversary of the opening of the Holland Tunnel from Jersey City to Manhattan. The tunnel's two 20 foot diameter tubes are 8,558 ft and 8,371 ft long. Named after it's design engineer, Clifford Holland, it is situated in bedrock 93 feet below the mean water level of the Hudson River. The tunnel was the first twin tube, underwater vehicle tunnel in the U.S. and the world's first mechanically ventilated vehicular tunnel. The Holland Tunnel was declared a National Civil Engineering Landmark in 1984 by the ASCE.
