The ‘Dutch Tunnel’ is a road tunnel that runs under the Hudson River. It connects New York's Hudson Square neighborhood in Lower Manhattan to the east, and Jersey City, New Jersey, to the west. Like most of the other tunnels, it is under the control of the Port Authority of New York.
The “Dutch Tunnel” is located on Highway 78. In the USA, road junctions have multiple crossings. And so the "Dutch Tunnel" is one of the transitions between Manhattan and New Jersey. Also the top three includes the ‘Lincoln’ Tunnel and sufficiently well-known the ‘George Washington’ Bridge.
The idea of creating a new road tunnel was born in 1906, it was then that the first project was developed. But due to some disagreements in the discussion, the project was suspended until 1919.
The actual construction of the ‘Dutch Tunnel’ began in 1920, and the tunnel became accessible to traffic in 1927. It is worth noting that at the opening stage, the ‘Dutch Tunnel’ was the leader in length among other underwater road tunnels.
Initially, the “Dutch Tunnel” was called another road interchange - the ‘Hudson River’ or the ‘Street Canal’ road tunnel. But soon the municipal government decided to rename it in honor of Clifford Milburn Holland, the tunnel engineer.
The tunnel is not only an important traffic interchange. In 1982, the "Dutch Tunnel" was declared a National Historic Monument of civil engineering and machine building.
