A6144(M) motorway ceased being a special road on 25 May 2006 losing its motorway status. It is now subject to a 50 mph (80 km/h) speed limit and is classified as the A6144. The road through Sale retained the A6144 number, meaning that there are two branches (and two junctions with the M60 motorway) with the same road number. Despite losing motorway status, the road still prohibits pedestrians, cyclists, and horse riders. Following the change of signage on 25 May 2006, two marker posts, the A6144(M) confirmation sign and a lay-by warning sign are privately preserved. A6144(M) motorway The A6144(M) was a
