This photo from 1996 gives a good indication of how much construction work was required to extend the M65 from Blackburn towards Preston.

The new stretch of motorway would eventually run across the photo - you can see the giant concrete slabs which would support it as it went over the road.

This is the Riley Green junction between Feniscowles and Withnell.

Once complete cars would head along Finnington Lane towards the top of the picture to get to Hoghton and Blackburn
