The road forms part of the A625. Until 2000 the entire course of Hathersage Road was numbered A625. Hathersage Road is now only numbered A625 as far as the junction with Stony Ridge Road where the A625 proceeds towards Calver. Between Hathersage and Stony Ridge Road junction, Hathersage Road is numbered A6187. A section of the A625 was severed in 1979 due to a landslip at Mam Tor hence the re-designation of the road number for part of the route.
