The A601(M) is a short motorway in Lancashire, essentially forming a bypass of Carnforth. It runs from the Carnforth Interchange on the M6 (J35) to J35A and was formerly part of the M6 Lancaster Bypass. The Carnforth Interchange was constructed when the M6 was extended northwards. For many years, it was an unnumbered spur of the M6, however it gained the number A601(M) when the Carnforth Link was constructed to extend the motorway southwards (and complete the bypass of Carnforth).
In 1985, legislation was enacted to allow the construction of single carriageway road (known as the Carnforth Link), with motorway status and corresponding 70 mph speed limit. This was opened in 1987 and connected the east side of the roundabout to the nearby B6254, to enable quarry traffic from the Over Kellet quarries to bypass Carnforth village. At this time This and the old north-westerly spur were given the number A601(M), which was an odd choice as the A601 is quite elsewhere. The road therefore reached a maximum length of 1.3 miles.
In 2020, the Carnforth Link and circulatory carriageway of the roundabout was downgraded to become the non primary B6254.
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.
