Bikecentennial '76 was a bicycle tour across the United States in the summer of 1976, in commemoration of the bicentennial of America's Declaration of Independence. The route crossed ten states and 112 counties in either direction between Reedsport, OR, and Yorktown, VA, a distance of about 4,250 miles (6,840 km). The route was chosen to include many historic sites, but avoid the Great Basin desert, major highways, high-traffic zones and big cities. This route is still in use as the TransAmerica Trail and U.S. Bicycle Route 76. Astoria, OR, was an alternate western terminus, with four additional counties.

The 4,100 riders who participated represented all fifty states, and ~10% were from foreign countries. Just over 2000 cyclists rode the entire length of the trail.
Maps for the trip are produced by Adventure Cycling Association.
