Grimshaw Road, Skelmersdale
The B5312 starts off at a large roundabout junction with the A577 (which has a huge amount of room for a flyover) southeast of Skelmersdale. From here it heads westwards -- as the main route into the town centre – encountering en route two GSJs providing local access and equipped with pedestrian overbridges.
The B5312 then reaches an elongated roundabout known as 'Bone Island'. Here too, there is more than enough room for a flyover. The route continues westward, becoming an S2 road. On this stretch there are two roundabouts giving access to industrial estates and a third, more recent, roundabout links to a small housing estate.
After this, the road turns northwestward. At a T-junction the straight-ahead direction will take you along a new branch of the B5312 for a short distance to meet the A577 once again, or you can turn left to continue through countryside along the original route, which terminates at a roundabout junction with the A570 immediately northwest of junction 3 of the M58.
