The B6240 is a short link road in Burnley town centre.
The road starts at a roundabout where it meets the A671 and A682. It heads northeast along Manchester Road, crossing the Leeds & Liverpool Canal, before turning left at traffic lights onto Hammerton Street. This becomes the modern Queen's Lancashire Way, which ends at a roundabout on the A679.
The original route of the B6240
In 1922, Manchester Road was numbered A56, Hammerton Street was unclassified and Queen's Lancashire Way did not exist. The B6240 did start in the same place as it does now - but headed northwest along Trafalgar Street to reach the A671.
Later maps show that when the A56 was rerouted onto Centenary Way the old road as far as the A671 Yorkshire Street was given Class II status; it is likely that its number was B6240.
Later still, Yorkshire Street was pedestrianised. As such, the A671 was rerouted onto Trafalgar Street to pass through town. The B6240 was also rerouted, to give the road its current route.
