Notes: Archives 2011.052.0231 HOLLAND TUNNEL THE FAMOUS LINK BETWEEN NEW JERSEY AND NEW YORK FROM 12th STREET, JERSEY CITY TO CANAL STREET, NEW YORK CITY - CONTROLLED AND OPERATED AS A PUBLIC TRUST BY THE PORT OF NEW YORK AUTHORITY - HOLLAND TUNNEL - The world's busiest vehicular tunnel, named in memory of its Chief Engineer, the late Clifford M. Holland, passes under the Hudson River at the Port of New York, between 12th Street, Jersey City, N. J., and Canal Street, New York, N. Y. It provides direct access for vehicular traffic between New Jersey and lower Manhattan, and offers a short route to and from Brooklyn, Queens, and the rest of Long Island, via the Brooklyn, Man- hattan, and Williamsburg Bridges over the East River. The Holland Tunne! consists of two tubes, one for eastbound and one for westbound traffic, each two lanes wide. The tubes were built by the "shield method" of construction, a steel cylinder, known as the tunnel shield, being employed to bore through the river bed. The tunnel is built of cast iron, in the form of rings 2 feet 6 inches long, each made up of fifteen segmental castings. Inside this cast iron ring is a lining of concrete 19 inches thick. The road- ways are paved with granite blocks. The side walls are faced with white vitreous tile, in which markers are set at quarter mile points and at the New York-New Jersey state line. The tunnel is ventilated by the "distributive" method. Fresh air is supplied at all points through- out the length of the tunnel, just above the pave- ment surface, and vitiated air is removed through openings located at frequent intervals in the ceiling. Air is brought into the tunnel through a duct beneath the roadway, and is removed through a similar duct above the ceiling. Air is moved through each of these ducts by means of blower and exhaust fans located in four ventilation build- ings, two on the New York side of the river and two on the New Jersey side. On the average, the air remains in the tunnel only 1 1/2 minutes as it slowly rises from the roadway level to the ceiling. Electric power is used for operation of ail of the fans. The Holland Tunnel was constructed by the States of New York and New Jersey, acting through State Commissions. Construction was begun on October 12,1920, and the tunnel was opened to traffic on November 13, 1927. In Apri 1930, the States appointed The Port of New York Authority-a public body created by the States of New York and New Jersey with the consent of Congress- as their agent for operation of the tunnel, and in March, 1931, they vested full control in the Authority. An issue of $50,000,000 of Port of New York Authority bonds was sold at that time to provide funds to reimburse the two States for their investment in the project. - Tunnel Data NORTH TUNNEL - Westbound Traffic Length of Tunnel ... 9, 180 feet Distance between Portals ... 8,557 feet SOUTH TUNNEL - Eastbound Traffic Length of Tunnel ... 9,277 feet Distance between Portals ... 8,371 feet Length of Under River Portion ... 5,480 feet Width of Roadway 20 feet.
