This article is about the Class III road numbered C627 maintained by DfI Roads. For other roads numbered C627, see C627.
The C627 is a lengthy route running through central Tyrone. It starts at a junction by the Sandvik works on the B34 (former A4) north east of Ballygawley. The road crosses the Ballygawley River as it passes its junction with the C635, heading north west. The road next encounters the C633 at two separate junctions - firstly crossing the route at a crossroads followed by a T junction from which the C627 TOTSOs north to meet the B46 in Sixmilecross. The road continues north westwards out of the village and soon TOTSOs right, albeit keeping north west and meeting the C628 at a crossroads. Just before crossing the Camowen River a spur heads south, TOTSOs south west and crosses the B158 before linking to the A5 south of Omagh. Eventually the road comes to an end on the B4 and the B158 at a roundabout in the outskirts of Omagh.
