|Route outline (key)|
The B4419 is a rural B-road on Anglesey.
The road starts on the A5 in the centre of Pentre Berw and heads southwest. Firstly it crosses the easy-to-miss and now-disused railway branch line to Llangefni then the line from Crewe to Holyhead. The B4419 then arrives at Llangaffo. It TOTSOs left here and the B4421 continues ahead.
The road then crosses a valley and a small hill before going over the River Braint to reach a T-junction on the A4080 near Bryngwyn. There is a short multiplex south before the B4419 regains its number by taking the next left turn.
Now narrower than before, the B4419 makes a beeline for the sea, which only becomes visible at the last minute. The road reaches a T-junction right on the edge of the Menai Strait. The road TOTSOs right, signed as a no-through-road. It passes Foel Farm Park before petering out at the next cluster of buildings, one of which used to be the Mermaid Inn.
