|Route outline (key)|
The original route of the B4366 ran through three counties on the border between England and Wales.
It started on the A49 at Bromfield, a few miles west of Ludlow. The road headed west via Leintwardine and the valley of the River Teme before entering Wales just beyond Brampton Bryan. It continued to follow the river to Knighton, where it ended on the B4359 on the edge of town.
The road was quickly upgraded to Class I status. In the mid-1920s it was renumbered A4113, which it remains.
