In 2003, at the urging of D.C. Congressional Delegate Eleanor Holmes Norton, the GSA conducted a nationwide request for proposals among private sector real estate developers to determine interest in acquiring the former Navy Yard Annex site for redevelopment, including its several remaining historically protected former industrial buildings. The US Department of Transportation contracted with a private sector developer for the design and construction of its dramatic new headquarters building on what was formerly the northern edge of the Navy Yard Annex site at the corner of M Street and New Jersey Avenue SE.
