U.S. Route 101
U.S. Route 101, or U.S. Highway 101 (US 101) is a north–south United States Numbered Highway that runs through the states of California, Oregon, and Washington, on the West Coast of the United States. It is also known as (The Royal Road) where its route along the southern and central California coast approximates the old trail which linked the Spanish missions, pueblos, and presidios. It merges at some points with California State Route 1 (SR 1).
North Carolina Highway 101
NC 101 was an original state highway appearing on a 1922 state map of North Carolina. NC 101 started at former NC 10 south of Havelock. NC 101 then went southeast through the town of Newport, and the communities of Mansfield and Wildwood. NC 101 had its eastern terminus in Morehead City. In 1928 NC 10 and NC 101 swapped routing. When NC 10 and US 70 were extended to Atlantic in 1931, NC 101 was truncated east of Beaufort. The routing has been the same since 1931.
