The B6527 is a short link road in south-east Lancashire which follows the former alignment of parts of the A680 and A56, which were replaced through the Rossendale Valley by the modern alignment of the latter road in the late 1970s.
The road starts at a large grade-separated roundabout on the A56 in Bent Gate. The A680 also runs north from here whilst we take on that road's former route south. We follow Manchester Road through a surprisingly rural section but quickly reach the village of Ewood Bridge. We cross the bridge over the River Irwell then go over the preserved East Lancashire Railway to reach open country. In British Rail days there was a station here but the line closed in the 1970s.
The road then appears to bear right to avoid the A56; in reality the road has always gone this way and it is only the gradient we are avoiding. That road is invisible until we bear left to go under it, after which we continue along Blackburn Road into Edenfield. At traffic lights we join the original line of the A56 (briefly numbered B6526 to the left but now unclassified) and follow it to the right. We follow Market Street through the centre of town and shortly reach a mini-roundabout. Two roads continue ahead, at a sharp angle to each other; both are the A680 making this the end of our road. At one time the left-hand road was the A627 whilst the other was the continuation of the A56.
