M271 motorway

The M271 is a 3-mile-long (5 km) motorway near Southampton in Hampshire, England. Construction began in 1973 and it opened in 1975. It provides part of the route to Southampton Docks from the M27, which in turn makes up another part of the route to the docks from the nearby M3 Motorway.

Route

The motorway begins at Redbridge near Totton at a grade separated roundabout with the A35, heading north, briefly as a dual three-lane motorway. At its first junction, it reduces to two lanes and continues east of Hillyfields. After a further 1 mile (1.6 km) it reaches a junction with the M27 at a signal controlled roundabout. North of the M27 it enters the countryside and terminates after a further mile of dual two-lane road at another roundabout, this time with the A3057 near Upton.

In 2019, improvement works to Redbridge Roundabout at the southern end, introduced a dedicated lane to connect the M271 with the A33 towards the docks in a free-flow interchange.
