According to the AASHTO's numbering scheme for U.S. Highways, three-digit route numbers are generally subsidiaries of two-digit routes. AASHTO, the American Association of State Highway and Transportation Officials, is a standards setting body which publishes specifications test protocols and The system of United States Numbered Highways (often called U However, the principal north-south routes were assigned numbers ending in 1. Rather than lose four available north-south numbers (93, 95, 97, and 99) or assign the primary west coast highway a "lesser" number, the AASHTO made an exception to its two-digit rule. Thus, U. S. 101 is treated as a primary, two-digit route with a "first digit" of 10, rather than a spur of U.S. 1. US Route 1 (US 1 is a major north-south US Highway that serves the East Coast of the United States. Thus U. S. Route 101, not U.S. 99, is the westernmost north-south route in the U. US Route 99 was the main north-south highway on the West Coast of the United States until 1964 running from Calexico California, on the U S. Highway system.
U. S. Route 101 was once the major north-south link along the Pacific coast.

In 1964, California truncated its southern terminus in Los Angeles, as Interstate 5 replaced it. The old road is known as county road S-21 or Historic Route 101 in northern San Diego County.
The highway's "northern" terminus is in Olympia, Washington, though the northernmost point on the highway is in Port Angeles. Olympia is the Capital of Washington and is the County seat of Thurston County. Washington ( is a state in the Pacific Northwest region of the United States. Port Angeles is a city in and the County seat of Clallam County, Washington, United States. The southern terminus of U.

In 1964, when California renumbering numerous state highways, El Camino was renumbered California 82 and the Bayshore Freeway lost the Bypass designation.
