Commissioner's Plan of 1811 in the context of "Hamilton Fish House"

155th Street is a crosstown street separating the Harlem and Washington Heights neighborhoods, in the New York City borough of Manhattan. It is the northernmost of the 155 crosstown streets mapped out in the Commissioner's Plan of 1811 that established the numbered street grid in Manhattan.

The street consists of upper and lower portions, linked only by a steep pedestrian stairwell. The upper portion starts on the West Side at Riverside Drive, crossing Broadway, Amsterdam Avenue, and St. Nicholas Avenue. At St. Nicholas Place, the terrain drops off steeply, forming Coogan's Bluff. 155th Street is carried on the 1,600-foot (490 m) long 155th Street Viaduct, a City Landmark constructed in 1893, that slopes down towards the Harlem River, continuing onto the Macombs Dam Bridge, crossing over (but not intersecting with) the Harlem River Drive. An unconnected lower section of 155th Street runs at ground level under the viaduct, between a dead-end west of Bradhurst Avenue and a service road of the Harlem River Drive.

96th Street is a major two-way street on the Upper East Side and Upper West Side sections of the New York City borough of Manhattan. It runs in two major sections: between FDR Drive and Fifth Avenue on the Upper East Side, and between Central Park West and the Henry Hudson Parkway on the Upper West Side. The two segments are connected by the 97th Street transverse across Central Park, which links the disconnected segments of 96th and 97th Streets on each side.

96th Street is one of the 15 hundred-foot-wide (30 m) crosstown streets mapped out in the Commissioner's Plan of 1811 that established the numbered street grid in Manhattan. On Manhattan's West Side, 96th Street is the northern boundary of the New York City steam system, the largest such system in the world, which pumps 30 billion pounds of steam into 100,000 buildings south of the street. (The northern boundary on the East Side is 89th Street.)

23rd Street is a broad thoroughfare in the New York City borough of Manhattan, one of the major two-way, east-west streets in the borough's grid. As with Manhattan's other "crosstown" streets, it is divided into its east and west sections at Fifth Avenue. The street runs from Avenue C and FDR Drive in the east to Eleventh Avenue in the west.

23rd Street was created under the Commissioners' Plan of 1811. The street hosts several famous hotels, including the Fifth Avenue Hotel and Hotel Chelsea, as well as many theaters. Several skyscrapers are located on 23rd Street, including the Flatiron Building, the Metropolitan Life Insurance Company Tower, and One Madison.
