This article is about the Class III road numbered C551 maintained by DfI Roads.
For other roads numbered C551, see C551
The C551 starts at the western TOTSO of the A29 in the centre of Maghera, following Tirkane Road out of the town to the north west. Eventually the road reaches Upper Tirkane and TOTSOs north. Turning north east, the road encounters a pair of T junctions from which it TOTSOs right then left. After this the road TOTSOs once more, this time to the east which leads it back to the A29 at Swatragh.
