This article is about the Class III road numbered C345 maintained by DfI Roads.
For other roads numbered C345, see C345
The C345 is a road of two parts, separated in the middle by a multiplex with the B10 over a kilometre in length. The road starts on the A1 south of Lough Brickland and briefly follows the A1's old alignment before turning north east along the shores of the small lough. After crossing the B3 the road turns towards more of an easterly direction as it passes the southern end of the C348. Soon the western half of the road comes to an end where it meets the B10 almost immediately after crossing the C340. Further along the B10, the road resumes again and crosses the C347 on its way to the B25 just across the Upper Bann from Katesbridge.
