This article is about the Class III road numbered ZC24 maintained by Edinburgh Council.
For other roads numbered C24, see C24
The ZC24 starts on the ZC5, York Place, and heads south along North St Andrew Street, across the east side of St Andrew Square and on down South St Andrew Street to meet Princes Street. The other three sides of the square form the ZC23. Both ends of the route have now been closed up to traffic and are only open to trams which run along the route. This also means that the entire route is now one-way southbound.
