Madison Avenue Bridge

The Madison Avenue Bridge is a four-lane swing bridge crossing the Harlem River in New York City, connecting Madison Avenue in Manhattan with East 138th Street in the Bronx. It was designed by Alfred P. Boller and built in 1910, doubling the capacity of an earlier swing bridge built in 1884. The bridge is operated and maintained by the New York City Department of Transportation.

For 2011, the NYCDOT reported an average daily traffic volume in both directions of 41,423; having reached a peak of 49,487 in 2002. Between 2000 and 2014, the bridge opened for vessels 69 times.
