National Old Trails Highway (NOT) 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 3,095 miles long and stretched from Maryland to California. Much of the route follows the old National Road and the Santa Fe Trail.

The routing itself remained under much discussion till 1917. In particular the western end was heavily discussed with proposed alignment going though Phoenix, Arizona, via San Diego, California, up to San Francisco, California. Eventually however the alignment below was agreed upon. It's an alignement which also follows the earlier indian paths and the -by that time- existing railroad.

Throughout its life the road got upgraded and realigned in order to build a better road. But by 1926 much of the western portions were by still hard work to drive and much of it was still unpaved.

In 1926, the section west of Moriarty, New Mexico to Los Angeles, California was certified as U.S. Highway 66, (now better known as Route 66) by the AASHTO.


In 1928 and 1929, the Daughters of the American Revolution (DAR) had Madonna of the Trail monuments placed in each of the 12 states the highway passes through.

After Route 66 was decomissioned in California parts of it in eastern California got known again under the old name and signed accordingly.
