The M27 is a

motorway in Hampshire, England. It is 27.9 miles (44.9 km) long and runs between Cadnam and Portsmouth. It was opened in stages between 1975 and 1983, providing the largest two urban areas in Hampshire (Southampton and Portsmouth) with a direct motorway link. An extension into the county of West Sussex was planned but never constructed.[1] A number of smaller motorways were proposed, connecting the city centres of Southampton and Portsmouth to the motorway;[2] 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.

Route

Running approximately parallel both to the coast of the

hard shoulders being too narrow. Although the M275
which the M27 junctions with, has no hard shoulders along its entire length.

History

Opening dates

The M27 was opened in stages (in common with many UK motorways) between 1975 and 1983.[3]

  • Junction 1 to 2 opened 20 August 1975
  • Junction 2 to 4 opened in December 1975
  • Junction 4 to 7 opened in 1983
  • Junction 7 to 8 opened in February 1978
  • Junction 8 to 12 opened in March 1976

The South Stoneham Crematorium, which was located north of South Stoneham Cemetery, was demolished during 1973 to make way for the construction of the M27 motorway. The South Stoneham garden of remembrance is now located at the north end of the cemetery, adjacent to the motorway.[4]

Unfulfilled plans

It has been said[clarification needed] that the M27 was intended as a motorway connecting south coast towns from Penzance to Ramsgate.[5] However the only proposal of a route similar to that was by the Institution of Highway Engineers in 1936.[1][6][7] Road developments in the

national park
status.

The M27 was meant to be extended to Chichester; a sign of this is the width of the A27 road between junction 12 and the junction with the A3(M), which has three or four lanes, a hard shoulder and grade-separated junctions. It is not part of the M27 as its hard shoulders are not quite wide enough to comply with motorway regulations.[1][8]

The M272 was meant to go from junction 5 through Portswood to the centre of Southampton. The M272 was instead built (in much-reduced form) as the

A335 Thomas Lewis Way.[9]

Junction 6 was never built – there were plans for a motorway spur (probably to be numbered M273) connecting the M27 to the centre of the Townhill Park area of Southampton.[2]

A planned

service area just east of junction 9 was never constructed. The long westbound exit slip road at junction 9 was designed to allow an entry to and exit from the service area.[10]

2015 incident

In November 2015, an elderly woman died after falling from the A3057 bridge that crosses over the M27, into westbound traffic, just before junction 3. She had not taken her anti-psychotic medication, and escaped from her Southampton home through an upstairs window before climbing off the garage roof and running away.[11][12]

Smart motorway conversion

In March 2018, work began to convert the section between junctions 11 and 4 to a smart motorway. The scheme will turn the hard shoulder into a permanent fourth running lane, adding refuge areas along the route and installing new CCTV and speed cameras with mandatory variable speed limit signs.

In early January 2019, official work began when average speed cameras were switched on between junctions 5 and 4. Average speed cameras further along on the scheme will be turned on as work continues along the route. The work has suffered repeated delays, originally due to be complete in Spring 2021. The commissioning phase began in mid February 2022, during which time the smart motorway technology will be tested, including stopped vehicle detection radars. This is with a fully open carriageway and a 60 mph (97 km/h) speed limit controlled by electronic signs on new gantries and CCTV and speed cameras. The 60 mph limit was lifted on 29 June 2022 when the upgraded section was fully opened and returned to the

national speed limit.[13]

Junction 1 is about 1,800 metres (2,000 yd) (2,400 metres (2,600 yd) by road) from The Rufus Stone, where King William II, also known as William Rufus, was killed in what may have been a hunting accident in 1100.[15]
