The A6144(M) (also known as the Carrington Spur) is a former motorway running from the A6144 in the Northwes of Sale to meeting the M60 at Junction 8. The motorway was downgraded in 2006, likely because it was, and still is a single carrigeway. This means there is now TWO A6144/M60 junctions.
This is probably very confusing for drivers.
