It was completed in 1906 under IRT Contract 1.","why_significant":"The station is significant for transportation, community planning and development, and social history as one of the original IRT elevated stations. It is also significant for engineering and architecture as a unique Beaux-Arts station and control house by Heins & LaFarge, built into a hillside beside the Fort George Tunnel. It retains a relatively high degree of integrity.","narrative":"Dyckman Street Station is an elevated subway stop in Washington Heights, Manhattan, opened in 1906 as part of the original Interborough Rapid Transit system. It sits on a triangular island between Hillside and St. Nicholas Avenues, where the line emerges from the Fort George Tunnel and meets grade. A wedge-shaped Beaux-Arts control house of concrete patterned to imitate ashlar stone supports the tracks and platforms above. Platforms carry trussed-steel canopies and cast-iron railings typical of early IRT elevated stations. The tunnel portal, also by Heins & LaFarge, has a rusticated granite arch and the inscription \"Fort George 1776-1906.\" The station is significant for its role in transportation and in the growth of upper Manhattan and the Bronx. It is also valued as a unique Beaux-Arts design among mostly similar elevated stations, engineered by William Barclay Parsons. The control house interior was renovated in 1990-1991, though much original fabric remains.","period_of_significance":"1906-1908","architect_builder":"Parsons, William Barclay (engineer); Heins, George L. and LaFarge, Christopher G.
