I'll look for that next time I see the episode. What I had noticed was part of the route the trio took bringing the plank to the cafe. It passed in front of The Nook brewpub, which we don't see, then across Higgen Brig over the River Ribble, with a pause for Compo's reminiscences of one of his girlfriends, then out past where the cobbler's shop is now. That scene shows how much the area has been cleaned up in the intervening years.
