The Headquarters of PHMSA and DOT moved to 1200 New Jersey Avenue, South East, in Washington DC, in the Summer of 2007. The area is in a period of intense renovation centering around the waterfront revitalization and construction of the Washington Nationals baseball stadium.
WARNING: Due to the changes, the DOT buildings and address do not appear on most electronic maps, GPS, or online direction tools. If an address is identified by your electronic system, please be certain the New Jersey Ave. address provided is not within another quadrant of the city (ie. NE, NW, or SW).
The directions and maps found here should assist you while this period of construction and change continues.
