This article is about the Class III road numbered ZC6 maintained by Edinburgh Council.
For other roads numbered C6, see C6
The ZC6 starts on the A900, Leith Walk, a little to the north of the city centre, and heads north west along Pilrig Street. After crossing the B900 at Bonnington Toll junction, it continues along Newhaven Road via Bonnington Bridge to cross the A902 Ferry Road. North of Victoria Park, another bridge carries it over the former railway line between Trinity and Leith, which is now a foot and cycle path. However, before reaching the centre of Newhaven, the ZC6 turns left onto Stanley Road, and then right onto Craighall Road to meet the A901 at a roundabout.
