This article is about the Class III road numbered C650 maintained by DfI Roads. For other roads numbered C650, see C650.
The C650 consists of a loop on the north side of the A4 running between Augher and Drumcorke. The road starts on the A4 at a mini roundabout in the village of Augher and heads north west. After crossing over the River Blackwater the road TOTSOs north and gradually meanders its way north east and then eastwards. As it does so it crosses the C651 at Ballynasaggart. The road eventually returns to the A4 at Drumcorke to the east.
