|Junctions related to the A601(M)|
When the M6 Lancaster bypass was first opened in 1960, there was nothing here but a "temporary bend", a bridge over the Lancaster Canal (with two separate decks, one for each carriageway), and a change in width of the central reservation. (To the south it was wide enough to allow a third lane to be added to each carriageway, to the north-west not). Accidents on the bend caused the "sharp bend ahead" sign to be trialled here.
A roundabout interchange was created here when the mainline was extended north, opening in 1970. The former north end of the bypass became a spur. A new canal bridge was built for the southbound carriageway of the spur, leaving the former southbound deck unused. A footbridge over the M6 mainline a short distance to the south was demolished as it was incompatible with the new slip roads.
In 1985, legislation was enacted to allow the construction of single carriageway road (known as the Carnforth Link), with motorway status. This was built and connected the east side of the roundabout to the nearby B6254, to enable quarry traffic to bypass Carnforth village. This and the old north-westerly spur were given the number A601(M), which is odd as the A601 is quite elsewhere.
In 2020, the Carnforth Link and circulatory carriageway of the roundabout was downgraded to become the non primary B6601.
