National Old Trails Road, also known as the Ocean-to-Ocean Highway, was established in 1912, and became part of the National Auto Trail system in the United States. It was 3,096 miles (4,983 km) long and stretched from Baltimore, Maryland (some old maps indicate New York City was the actual eastern terminus) to California. Much of the route follows the old National Road and the Santa Fe Trail. Following its decommission, the western portion was later integrated into U.S. Route 66.
