The former B4423 (now B5112) south of Trefor
The B4423 was, aside from a last minute allocation in Carmarthen, the highest numbered 4-zone road in the 1922 Road Lists. As might therefore be expected, it ran in the west of Anglesey near the end of the A5.
The road had a roughly north-south route, starting at the western end of the B4422 in Llanfaelog and heading vaguely northwards. It crossed the A5 near Bryngwran before ending in Trefor, from where the B5112 headed west to Bodedern or north to Llanerchymedd.
In the 1935 Road numbering revision, the section to the south of the A5 was upgraded to become part of the A4080, while the northern third was renumbered as a rerouted B5112.
