This article is about the Class III road numbered ZC25 maintained by Edinburgh Council.
For other roads numbered C25, see C25
The ZC25 starts at a signalised junction towards the southern end of Leith Walk, the A900. It heads north west along Annandale Street, then turns left at the roundabout onto East London Street, crossing the B901 at another Roundabout to reach Drummond Place. It is not clear whether the route includes just one side or all of the square, before it continues west along Great King Street. At the end, there is a dogleg onto South East Circus Place. It then passes through the middle of Circus Place, leaves on North West Circus Place before following the short Kerr Street to meet the B900, Hamilton Place.
