Holland Tunnel

The Holland Tunnel is a vehicular tunnel under the Hudson River. It connects Manhattan in New York City, New York, to the east, and Jersey City, New Jersey, to the west. An integral conduit within the New York metropolitan area, the Holland Tunnel is operated by the Port Authority of New York and New Jersey. The entirety of the tunnel carries Interstate 78; the New Jersey side also carries New Jersey Route 139.

Plans for a fixed vehicular crossing over the Hudson River were first devised in 1906. However, disagreements prolonged the planning process until 1919, when it was decided to build a tunnel under the river. Construction of the Holland Tunnel started in 1920, and it opened in 1927. At the time of its opening, the Holland Tunnel was the longest continuous underwater vehicular tunnel in the world. The Holland Tunnel is one of three vehicular crossings between Manhattan and New Jersey, the others being the Lincoln Tunnel and the George Washington Bridge.
