Madison Avenue Bridge
The Madison Avenue Bridge connects 138th Street and Madison Avenue between Manhattan and the Bronx over the Harlem River. The bridge features a 300-foot swing span with two 27-foot-wide roadways and two 9-foot-wide sidewalks. The bridge was the last of the three Harlem River bridges designed by by Alfred P. Boller and based on his designs for the McCombs Dam and 145th Street Bridges. The bridge opened for traffic on July 18, 1910.
