1956 BPR issues PPM 20-7 on "Archeological and Paleontological Salvage." It is superseded on October 19 by a revised PPM implementing Section 120 of the Federal-Aid Highway Act of 1956, under which Federal-aid highway funds may be used by State highway departments for archeological and paleontological salvage in compliance with An Act for the Preservation of American Antiquities (June 8, 1906) or State laws. The October 19 PPM states, "When a road location or improvement is in an area where it is anticipated that historical objects may be encountered, the appropriate authority should be advised as early as possible of the exact location of the road to enable such authority to determine the likelihood of the highway destroying historical objects."
