This article is about the Class III road numbered C108 maintained by DfI Roads. For other roads numbered C108, see C108.
The C108 is an entirely urban C road within Antrim. It follows Fountain Hill as it leaves the A522 at a roundabout and is initially dual carriageway until not long after its junction with the start of the B95 (Greystone Road). It should be noted that certain maps and signage dispute the starting point of the B95 with some claiming that the B95 does in fact start on the A522 and briefly follows Fountain Hill before turning off onto Greystone Road in which case this junction would mark the start of the C108. North of the junction, the C108 continues to follow Fountain Hill as it becomes single carriageway and the B518 is soon reached on the edge of the town.
