The A601(M) was a motorway in Carnforth, Lancashire, England. It was at the time of its downgrade a 1.3 miles (2.1 km) long dual carriageway, meeting the M6 at Junction 35. It is no longer a motorway but remains open, as part of the B6601 and A6070.

Originally built in 1960 as the northern terminus of the M6 on the A6, the A601(M) became a spur to the M6 in 1970 when the mainline of the motorway was extended north. A short single-carriageway extension to the south of Junction 35 was opened in 1987, to connect to the B6254, and the road was renumbered the A601(M). This southern extension was reclassified as the B6601 in 2020, and the remainder of the motorway became part of the A6070 in 2023.

History

The section between the M6 and junction 35A was originally opened in 1960,^[2] as part of the Lancaster Bypass.^[3] This was a two-lane motorway. In 1970,^[3] the M6 was extended north, and a short spur was left to the A6. The terminal roundabout was given the junction number 35A. Plans existed to extend this as part of an Arnside link road, which would have connected the Furness Peninsula with the M6, but they were scrapped for environmental reasons.^[4]

In 1987, a link was constructed with the B6254, to remove traffic for Over Kellet Quarries and Kirkby Lonsdale passing through Carnforth. The road was then renumbered as the A601(M). No junction number was given to this terminus.^[5] The numbering A601(M) was somewhat anomalous: normally in the UK such a designation would indicate that the road was the A601 under motorway restrictions. However the A601 is the Derby inner ring road, over 100 miles (160 km) away, and the numbering appears to have been the result of an oversight that this road already existed. ^[5]

In early 2020 the link road was downgraded to become the B6601 road to allow for an access for a car dealership to be built on it.^[6] In late 2021, Lancashire County Council issued a revocation scheme for the remaining portion of the motorway to be downgraded to non-motorway status.^[7] The revocation scheme was approved by the Secretary of State on 7 February 2023, and came into force that day.^[8] The road was renumbered as an extension of the A6070, and future works will reduce the speed limit reduced to 50 mph (80 km/h) and remove the hard shoulder in order to reduce maintenance costs. ^[6]
