1912 – Manhattan Bridge, New York
The Manhattan Bridge connects Lower Manhattan (at Canal Street) with Brooklyn. It was the last of the three suspension bridges built across the lower East River, following the Brooklyn and the Williamsburg bridges. Construction started in 1901 although the bridge did not open until 1912. It was designed by Leon Moisseiff who later designed the infamous original Tacoma Narrows Bridge that opened and collapsed in 1940.
It has four vehicle lanes on the upper level (split between two roadways). The lower level has three lanes, four subway tracks, a walkway and a bikeway. The upper level, originally used for streetcars, has two lanes in each direction, and the lower level is one-way and has three lanes in peak direction.
