The B4422 is a rural B-road on Anglesey.
Originally the road started at the southern end of the B4423 in Llanfaelog and ran eastwards, roughly parallel to the railway line into Bethel. In 1935 this section was bypassed by the new A4080, which runs further south via Aberffraw, and so the B4422 was cut back to Bethel. In fact, it was extended slightly along what had been the B4420 to meet the A4080 to the south of the village.
Now, therefore, the B4422 starts at the A4080 TOTSO to the south of Bethel. It heads north and crosses over a tunnel containing the Chester to Holyhead railway line before reaching Bethel itself. There is a T-junction where it meets the original line of the B4422 and the road TOTSOs right.
On leaving the village the road continues northeasterly passing several buildings but no places of any size. After a couple of miles it goes past Llangristiolus before crossing a bridge over the A55. A short distance further on the road reaches the A5.
Originally the B4422 ended here. However, in the 1960s it was extended straight across the A5 into Rhostrehwfa; now there is a short multiplex east along that road. The B4422 continues northeast into the suburbs of Llangefni, ending here at a T-junction on the B5109.
