M27 motorway

The M27 is a motorway in Hampshire, England. It is 25mi long and runs west-east from Cadnam to Portsmouth. It was opened in stages between 1975 and 1983. It is unfinished, as an extension to the east was planned. A number of smaller motorways were proposed, connecting the city centres of Southampton and Portsmouth to the motorway; of these only the M271 and M275 were built. Three sections of the M27 have since been widened to four lanes each way, the first between Junctions 7 and 8, the second between Junctions 3 and 4, and the third begins at the slip road where Junction 11 joins until mid-way to junction 12.
