The B6535 is a link road through Great Harwood in Lancashire. It was originally numbered A6064 but gained its present number in the 1970s.
The road starts at traffic lights on the A678 High Street in Rishton and heads north along the residential Harwood Road. After crossing the Leeds & Liverpool Canal the road reaches open country and then bears sharply right. By the time Great Harwood is reaches the road is heading northeastwards.
We follow Blackburn Road into the town centre then zigzag across adjacent mini-roundabouts onto Church Street, where the route becomes residential again. We bear right at a roundabout by the church and descend Park Lane. We continue east and end at a T-junction on the A680 on the edge of open country.
