text: Several other outstanding issues regarding Federal Triangle's development were also raised, and occasionally resolved, in the next half-century. The closure and elimination of Ohio and Louisiana Avenues NW led each state's representatives to seek to rename other streets in the District of Columbia after those states. Ohio Drive NW came into existence in 1949, after Congress passed legislation authorizing the name change of the drive along the Tidal Basin. Another issue remaining from Federal Triangle's development regarded the condemnation of railway tracks in the area.  The Mount Vernon, Alexandria and Washington Railway argued that it had not been properly compensated for the loss of its tracks in the area, and in 1943 sought federal relief.
  Some improvements were made to Federal Triangle, however.  In 1952, the Andrew W. Mellon Memorial Fountain was dedicated  within the eastern tip of the Triangle. A new cooling plant was built in 1960. Beginning in 1970, all the buildings were floodlit at night in order to reduce the level of crime in the area.
  In 1972, the Federal Triangle Washington Metro station was approved at Federal Triangle, and the station on Metro's Blue and Orange lines opened on July 1, 1977. Major heating, cooling, and electrical upgrades were made to the Archives, ICC, and Labor buildings and the Departmental Auditorium in 1984.
  After the terrorist bombing of the Alfred P. Murrah Federal Building in Oklahoma City on April 19, 1995 (which killed 168 people), security at Federal Triangle was tightened measurably and many of the pedestrian areas and buildings restricted to federal employees or those with official business. A major renovation for the Labor, ICC, and Post Office buildings was conducted in 1998.
