North Carolina Highway 13
|Existed:||early 1920s – 2005|
First NC 13
The first NC 13 was one of the original 1921 set of numbered North Carolina Highways. It ran northward from a junction with NC 10 in Durham, passing through Rougemont, Timberlake, and Roxboro before reaching the Virginia state line where it met what was then VA 18. In 1925, the routing between Timberlake and Roxboro was straightened. In 1927, the entirety of NC 13 was made part of the route of US 501. In 1930, the concurrent state highway number for this part of US 501 was changed to NC 55, ending the first NC 13.
Second NC 13
The second NC 13 was a short lived route, appearing only on 1935 state highway map as replacement for NC 21 from Raleigh to Creedmoor at a junction with US 15 and NC 56. By the following year it had been resigned as part of US 15-A 
Third NC 13
The third NC 13 was established in 1936 on a new primary highway route running from US 220 north of Seagrove northeast to US 421 in Staley. When US 13 was extended into North Carolina in 1951, rather than renumbering NC 13, it was simply demoted to secondary highway status except for the portion that was near NC 42.
Fourth NC 13
The northern terminus of the Fayetteville Outer Loop meets the southern terminus of US 13 at I-95 northeast of Fayetteville. It was not initially known whether it would be approved by American Association of State Highway and Transportation Officials (AASHTO) as an extension of US 13 or an auxiliary of I-95, so it was indicated on the 2004 and 2005 North Carolina Department of Transportation (NCDOT) highway maps as NC 13, though it was never signed as such in the field. The designation was dropped once AASHTO approved designating the loop as I-295 in 2005.
