The Jungbu Naeryuk Expressway Branch (Korean: 중부내륙고속도로지선; RR: Jungbu Naeryuk Gosok Doro Jiseon) is an expressway in South Korea, connecting Dalseong to Buk District, Daegu (30 km). It is numbered 451 and was formerly named the Guma Expressway (구마고속도로).
Originally, this route was called Daegu–Masan section (86.4 km). Due to a reform of Korean expressway route numbers in August 2001, the Masan–Hyeonpung JCT section was incorporated into the Jungbu Naeryuk Expressway.
In 2008, the Guma Expressway changed its name to Jungbu Naeryuk Expressway Branch.
