Federal Aid Highway Act of 1972 (S 3939). The bill authorized over $6 billion from the Highway Trust Fund for road construction. Of this amount, $2 billion could be used on a local option basis for bus transportation. The vote is on the Cooper-Muskie amendment to allow $800 million in the Urban Systems Fund to be used for rail transit as well as buses and highways. The Nixon Administration supported the amendment. (Adopted 48-26. September 19, 1972. "Yes" is the correct vote.)
