|Route outline (key)|
The original B4223 ran through the Forest of Dean to the east of Monmouth. As such it was the lowest numbered Class II road in Wales.
The B4223 started on the A466 on the far side of the River Wye from Monmouth town centre. It headed east through the forest, seemingly in no hurry as the road was very winding due to the terrain, eventually reaching the A40 at Huntley where it ended.
The road was deemed important enough to elevate to Class I status early on; in the late 1920s it became the A4136, which it remains, although the A-road is just as winding as the B-road was.
