The Northern River Street Historic District is located along River Street (southbound US 4 at that point) north of Federal Street, one block east of the Green Island Bridge, in Troy, New York, United States. It was added to the National Register of Historic Places in 1988, as the Northern River Street District, to distinguish it from Troy's previously existing River Street Historic District, which had been one of five superseded by the Central Troy Historic District to the south two years earlier. Its two acres (8,000 m²) include 13 brick industrial and commercial buildings erected from the mid-19th to early 20th centuries. They were cut off from the rest of downtown due to the construction of the Rensselaer and Saratoga Railroad, and as a result became a production center for the city's major industries, primarily textiles. When those industries declined in the mid-20th century, they were further isolated from the city's center by expansion of Federal Street to provide access to the bridge, and various urban renewal efforts. As a result, they have not seen much redevelopment and remain mostly intact.
