|Route outline (key)|
The B104 is a largely rural road in south County Antrim. It was originally unclassified but gained its number in the mid-1920s.
The road starts at traffic lights on the A3 to the west of Lisburn city centre and heads northwest along the residential Ballinderry Road, already hinting to the other end of the road. We soon go over the Belfast to Dublin railway line then pass an industrial estate to reach the A520 relief road; this is crossed at a staggered crossroads.
After passing a modern housing estate we enter open country and soon go through the small settlement of Magheragall. The road zigzags right-left for no obvious reason and then goes over the mothballed Lisburn to Antrim railway line. After crossing the Ballinderry River we reach the A26 Upper Ballinderry bypass. Originally this was crossed at a staggered crossroads but in the mid-2010s the road from this direction was diverted a short distance further north (with the old junction closed off) and so there's a short multiplex to the left to reach the original junction, from where the B104 still continues west.
After crossing the pre-bypass road through Upper Ballinderry (originally numbered B12) where we now have priority we continue back into open country. There's another crossing of the Ballinderry River but on the whole we continue across the fields until we enter Lower Ballinderry. The road ends here on the B12.
