Editing U.S. Route 1 (section)

==Auxiliary routes==

US&nbsp;1 has six three-digit auxiliary routes. In numerical order, these are:

*[[U.S. Route 201|US&nbsp;201]], from [[Brunswick, Maine]], to the [[Armstrong–Jackman Border Crossing]] running south to north in east-central [[Maine]].
*[[U.S. Route 301|US&nbsp;301]], from [[Sarasota, Florida]], to [[Biddles Corner, Delaware]], along the [[East Coast of the United States|East Coast]]. Most of the route closely parallels [[Interstate 95|I-95]] and it has numerous intersections with its parent.
*[[U.S. Route 401|US&nbsp;401]] from [[Sumter, South Carolina]], to [[Wise, North Carolina]], near the Virginia border. For most of the route, it parallels US&nbsp;1 about {{Convert|10|to|20|mi|km}} to the east, though the two share pavement in [[Raleigh, North Carolina]].
*[[U.S. Route 501|US&nbsp;501]] from [[Myrtle Beach, South Carolina]], to [[Buena Vista, Virginia]]. The highway runs southeast–northwest, meeting its parent in [[Aberdeen, North Carolina|Aberdeen]] and [[Sanford, North Carolina|Sanford]].
*[[U.S. Route 601|US&nbsp;601]] from [[Tarboro, South Carolina]], to [[Mount Airy, North Carolina]]. It runs mostly due south–north to the west of US&nbsp;501, meeting the parent route in [[Camden, South Carolina]].
*[[U.S. Route 701|US&nbsp;701]] from [[Georgetown, South Carolina]], to [[Four Oaks, North Carolina]]. Furthest east of the US&nbsp;1 auxiliary routes, it never meets its parent route, but does intersect US&nbsp;501 in [[Conway, South Carolina]], and terminates at US&nbsp;301 at its northern end.

[[U.S. Route 101|US&nbsp;101]], despite its number, is not an auxiliary route, but rather considered a primary U.S. Route in its own right as major highway west of the former [[U.S. Route 99|US&nbsp;99]] on the west coast of the U.S. (In the numbering scheme, its first "digit" is "10".)
