MTA New York City Transit is closing the No. 1 northbound platform beginning Oct. 18 and continuing through August 2011 for the first phase of the Dyckman Street station rehabilitation. Uptown No. 1 trains will bypass Dyckman Street.

The general scope of work includes repairing the stairs from the sidewalk into the station, restoring the concrete station wall along Hillside Avenue, replacement of the stairs connecting the control area to the platforms, repairing and painting the ceiling, and repairing damaged tiles.

At train level, the agency will demolish and rebuild the north and southbound platforms, demolish and reconstruct the platform structure and canopy, install new platform windscreens and repair the guardrails. The agency will also take this opportunity to replace the track along the entire station length. During second phase of the project, the southbound platform will be out of service between September 2011 and July 2012.

Opened in 1906, the Dyckman Street Station is of a design unique in the system and is listed in the National Register of Historic Places. The outdoor station, situated just north of the Fort Washington Tunnel portal, has two side platforms above a masonry head house.
