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.
