|Route outline (key)|
The B5112 is a rural road on Anglesey.
It heads north across the fairly flat Anglesey countryside. At Trefor it meets the B5109, which it crosses at a slightly staggered crossroads. The road now starts to head in a more easterlydirection. It climbs up to Carmel before descending again to Llanerchymedd. After going over the disused Amlwch Branch Line the road ends in the centre of the village at a mini-roundabout on the B5111.
The original number of the road south of Trefor was B4423. The 1922 route of the B5112 started in Llanynghenedl and headed east to Trefor before turning north and following its current route to Llanerchymedd.
