The M271 is a short motorway west of Southampton, serving the docks from M27.
Being west of the M3, it's often claimed that the M271 is in the three-zone, but this is not the case as the zone 2-3 boundary follows a theoretical straight-line continuation of the M3 from junction 8.
It is one of three (or arguably four) British motorways which negotiate a roundabout during their length, along with A627(M), A601(M) and arguably M58. Despite having four junctions, only one is numbered and grade-separated in favour of M271.
On pre-loaded VMS signs, Highways England refer to the southernmost section of the motorway as "J1-2". Assuming they are correctly referring to the Nursling Interchange as J1, this means that they want the roundabout at the southern end to be J2 and the first two roundabouts to be unnumbered.
