|Route outline (key)|
The road starts on the B6236 in Knuzden Brook, a suburb of Blackburn outside the administrative area, and heads east, climbing steeply along the southern edge of the built-up area before levelling out just in time to go over the M65.
After a short rural section with a 40mph speed limit the road soon becomes built-up again. It zigzags through the suburb of Stanhill before ending at a mini-roundabout on the B6231 by the church in Oswaldtwistle.
