High Quality Content by WIKIPEDIA articles! Dyckman Street is a street in the Inwood neighborhood of Manhattan, New York City. It is commonly considered to be a crosstown street because it runs from the Hudson River to the Harlem River and intersects Broadway. However, in its true geographical orientation, Dyckman Street runs roughly from north-northwest to south-southeast, and the majority of the street that lies southeast of Broadway runs closer to a north-south direction than east-west. It is located where West 200th Street would be: the sequence of numbered streets in this neighborhood has a gap between West 193rd Street and West 201st Street. As a rustic 18th century valley road lying between Washington Heights and Inwood Hill, it long preceded the comprehensive Manhattan grid plan, which was not applied in this small part of the island.
