Macombs Dam Bridge, Spanning Harlem River Between 155th Street Viaduct, Jerome Avenue, & East 162nd Street, Bronx, Bronx County, NY
- Upscale 2x6164x7680
Significance: The bridge was designed by eminent structural engineer Alfred Pancoast Boller and was a considerable municipal endeavor as well as a significant engineering feat. It is the third oldest major bridge in New York City, with the Brooklyn and George Washington bridges being the only ones older. It is the city's oldest intact metal truss swing-type bridge, which style was typically used in New York City along the Harlem River between the 1880's and 1910. The appearance of the bridge and viaduct is highlighted by the outline of the central swing span truss, the various steel latticework, the ornamental steel and iron details, and the large block masonry piers and abutments. It continues to provide a significant historic connection between upper Manhattan and the Bronx.
