NC 159 Spur is planned to be extended west of its current terminus on mainline NC 159 to the US 64 By-Pass. Construction on the new US 64 By-Pass began in 2016 and was completed in 2020, with the spur extension to begin at a later date. The new connector will alleviate traffic for those going to-and-from the North Carolina Zoological Park.[3][4]
Established in 1979 when NC 159 was redirected south to US 220. Its purpose is to connect the North Carolina Zoological Park with mainline NC 159. Though not signed along its route, it is listed on state and county maps and is the only known spur route in North Carolina.[6]
