10 3/4 x 16 1/2 in. unmounted albumen photograph showing the entrance to a bridge with signs on each side identifying the street as "Madison Ave." A sign hanging atop the bridge lists the names of the Commissioners of the Department of Public Parks in New York City for 1884, including Egbert L. Viele, Salem H. Wales, John D. Crimmins, and William Oliffe. The sign also notes that the bridge was built by the Keystone Bridge Company, identifying the engineers as Edgar B. Van Winkle & Alfred P. Boller. Six men, including one who appears to be a police officer, stand along the left side of the bridge deck.

The signage indicates that this photograph likely documents the swing bridge built in 1884 between the boroughs of Manhattan and the Bronx. It was later replaced by the Madison Avenue Bridge, which was designed by Alfred P. Boller and built in 1910.
