Why is it called Highway 1?

The entire length of the PCH stretches from north to south along the entirety of the United States' western border of the Pacific Ocean (hence the name, Pacific Coast Highway). ... For this reason, the highway wasn't always known as the PCH or the 1, as the first designated freeway in the United States from north to south.

Where does Highway 1 begin and end?

SR 1 has several portions designated as either Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 (I-5) near Dana Point in Orange County and its northern terminus is at U.S. Route 101 (US 101) near Leggett in Mendocino County.
