This article is about the Class III road numbered C64 maintained by DfI Roads. For other roads numbered C64, see C64.
The C64 starts on the A26 in the Ballykeel area of Ballymena and follows Crebilly Road eastwards across a bridge over the M2 and across the fields to a T junction on Deerfin Road. The C64 continues to the right along this road before splitting to the left and straight ahead. The route straight ahead shortly meets a TOTSO and follows Tully Road southwards past the Dunnyvadden Airfield and meeting the A36. Meanwhile, the road turning left is Caherty Road which heads north past its junction with the C66 and eventually coming to an end on the B94 in Broughshane.
