The A601(M) is a short motorway in Lancashire, essentially forming a bypass of Carnforth. The northern section of the motorway from J35 to J35A was formerly part of the M6 Lancaster Bypass, whilst the southern section is unusual.
As of 2018 there are plans for a large amount of development on the west side of the A601(M). The effects of this would be to incorporate a new roundabout into the northern section and a T-junction in the southern section. The motorway would require downgrading, presumably to an all purpose route.
Built to serve the Over Kellet quarries, the southern section is single carriageway with a single lane in each direction and is therefore one of the narrowest motorways in the United Kingdom. Despite this, the speed limit on the road is the standard motorway limit of 70mph.
The reason for the choice of the number A601(M) is highly unclear. No separate number was used until the single carriageway section was built.
