A23 road (Ireland) Wikipedia
The A23 is an 8.7 mile long road in County Down, in Northern Ireland. The route starts in near the Short Strand district in east Belfast and follows the Castlereagh Road through the southeastern suburbs of the city. Upon passing through the A55 Outer Ring Road, the A23 becomes the Ballygowan Road. It passes through the Castlereagh Hills and Roselawn Cemetery, where northern Irish footballer George Best is buried, and finishes in the village of Ballygowan at a roundabout with the A21.
