  ** ADVANCE FOR SUNDAY APRIL 22, 2012 AND THEREAFTER ** This April 1973 photo released by the U.S. National Archives shows the MBTA (Metropolitan Boston Transit Authority) tracks, crossing across Neptune Road in East Boston, Mass., near Logan Airport. The same view was photographed for the "Documerica" program, 1972-1977, instituted by the new Environmental Protection Agency, to document subjects of environmental concern.
