Macombs Dam Bridge in the context of "Coogan's Bluff"

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.

Macombs Dam Park (/məˈkuːmz/ mə-KOOMZ) is a park in the Concourse section of the Bronx, New York City. The park lay in the shadow of the old Yankee Stadium when it stood, between Jerome Avenue and the Major Deegan Expressway, near the Harlem River and the Macombs Dam Bridge. The park is administered and maintained by the New York City Department of Parks and Recreation. The majority of Macombs Dam Park was not open to the public from August 2006, when construction began on the new Yankee Stadium, to April 2012.

The 28.425-acre (115,030 m) park, prior to the stadium construction, featured baseball and softball diamonds, basketball courts, and football and soccer fields. Portions of the park are often used during New York Yankees home games to provide overspill parking for vehicles in an area underserved by garages and other parking facilities.
