|Route outline (key)|
The B159 ran from Cookstown to Omagh as an alternative to the B4, which it met at both ends. The road was originally unclassified, gaining its number in the late 1920s. However, it was obviously used more than the B4 as the road was upgraded to Class I status in the 1960s. It became the A505, which it remains, although the road has been improved and some of the corners straightened.
The road started on the B4 to the west of Cookstown and headed northwest into the hills. The B46 was crossed on the moors, after which the road wound to the west before descending. After passing Killyclogher the road returned to the B4 and ended on that road to the east of Omagh.
