The station was not originally built with the rest of the Red Line; the segment of the Red Line containing the site of this station opened in 1976. By 1996, however, the idea of a Metro station at
New York Avenue was being proposed as part of greater improvements of New York Avenue between Downtown Washington at the Maryland state line. In February 1999, the major property owners in the vicinity of the proposed station agreed in principle to contribute approximately $25 million in private financing for the project. The money would be collected from all commercial property owners within radius of the proposed station by being charged special tax assessments. The remaining costs would be split with $34 million coming from the District and $25 million coming from special tax assessments for the surrounding commercial properties. In May 2002, Metro awarded a
design–build contract to the
joint venture of Lane Construction/Slattery/
Skanska for the design and construction of the station. Since it was constructed along an existing line, its construction resulted in some delay for trains traveling on the Red Line during the construction of a
double crossover switch. On November 20, 2004, the station opened as the 84th station, and first infill station, on the Metro system within four weeks prior to the opening of
Morgan Boulevard and
Largo stations. The final cost was $103.7 million with the federal government and private land owners each contributing $25 million and the D.C. government contributing $53.7 million. The station was renamed to NoMa–Gallaudet U on November 3, 2011, and formally christened with the new name on June 13, 2012.
Future improvements There are plans to construct a pedestrian tunnel from the north entrance under the embankment to the east side of the tracks, and construction is scheduled to begin in 2028. ==Station layout==
