The B168 is a winding road in south County Tyrone, forming a hillier alternative to the parallel B83. It was originally unclassified but gained its number in the late 1920s.
The road starts on the B122 on the southern edge of Fintona and heads out of town along Aghafad Road; after several bends the road decides on a southeasterly course. Although the Quiggery River is to the right our road ignores it and so climbs up into the hills. Presently the road zigzags off to the right and descends into a valley; this is followed for a short distance then we cross the stream and go over a ridge to cross the River Blackwater. We then climb to journey's end at a T-junction on the A4.
