The two-level George Washington Bridge (GWB) crosses the Hudson River between upper Manhattan (West 178th Street) and Fort Lee, New Jersey and forms part of Interstate Highway I-95. This suspension bridge was designed by Othmar H. Ammann who was the Port Authority‘s Chief Engineer during that time. Ground was broken for the original six-lane bridge in October 1927.
The Port Authority opened the bridge to traffic on October 25, 1931.(The Building of the Bridge: A Gallery of Photographs) In 1946, two additional lanes were provided on the upper level. The lower level was opened on August 29, 1962. This increased the capacity of the bridge by 75 percent, making the GWB the world‘s only 14-lane suspension bridge, and it is now one of the world‘s busiest bridges. In New Jersey, the roadways leading to the bridge provide maximum flexibility permitting motorists to use either the upper or lower level. Two four-lane approach and departure roadways connect to the upper level, with connections to and from the lower level via two three-lane tunnels through the Palisades.
