This article is about the Class III road numbered C50 maintained by DfI Roads.
For other roads numbered C50, see C50
The C50 starts on the A42 in the village of Gracehill, located just west of Ballymena. From here the road heads south, meandering its way through the lowland landscape until it reaches a scattered crossroads with the B18. The road continues south where it is far straighter and follows the western banks of the River Maine. Along the way the road passes through the hamlet of Caddy and eventually comes to an end on the B93 just outside Randalstown.
