Approaching Shadsworth Roundabout.
Originally the Stanley (A693) to Hobson (A692) road (now B6173). The number was revived in 2005 for use in Blackburn in order to remove the duplicated A6177 number and also saw a return of the B6232.
The road itself is currently woefully over capacity, as it has not seen any significant upgrading despite the massive boom in development along its length since the completion of the M65 in 1997. It was originally very rural in character once it passed the former Queen's Park Hospital (now Royal Blackburn Hospital). The chain of roundabouts which due to the volumes of traffic clog up all approaches were installed in 2004.
Rumours have been floated that big improvements for the route are under consideration, but nothing has yet been confirmed.
