M27 junctions 4 to 11: smart motorwayRecently updated

We are upgrading the M27 between junction 4 (M3 interchange) and junction 11 (Fareham) by turning the hard shoulder into a permanent running lane making a dual four lane, smart motorway.

Region:  South East
Start date:  March 2018
Cost:  £244 million
Status:  PLANNED
Type:  Major Scheme
End date:  March 2021
Programme:  

Progress report

We are currently designing the smart motorway scheme on the M27 located in Hampshire between Junctions 4-11 and are undertaking a range of surveys and assessments to help inform us about the local environment.

We have begun discussions with local authorities and technical stakeholders.

What next?

We will be continuing with:

  • designing the scheme and carrying out environmental assessments
  • engaging with local authorities and starting our engagement with environmental bodies, local businesses, strategic traffic users and emergency services

Once we have a comprehensive design and have completed our environmental assessments, we will organise a series of Public Information Events (PIEs) in autumn 2017, to inform our customers, residents, local businesses, organisations, and visitors to the area about the scheme.

Why we need this scheme

The M27 is located in Hampshire, and falls within the Highways England Area 3 Asset Support Contract, as well as the South East Regional Control Centre. It is a key part of the strategic road network, providing a vital transport link between Southampton and Portsmouth, while also connecting to the M3 at junction 4, leading to Winchester and Basingstoke.

This route currently faces congestion during peak travel hours caused by the volume of traffic using the network.

Aims

The aims of this scheme are to:

  • reduce congestion and smooth the flow of traffic by turning the hard shoulder into a permanent running lane
  • improve journey time reliability on the strategic road network
  • support the economy and facilitate economic growth by providing increased capacity on the motorway
  • continue to deliver a high level of safety performance on the network using Smart Motorway techniques
  • minimise environmental impacts of the scheme and where possible allow for enhancements to be made to the environment

The scheme in detail

The M27 smart motorway scheme stretches from junction 4 (M3 Interchange) to junction 11 (Fareham), and will directly connect to the M3 junction 9 (Winchester / A34 Interchange) to junction 14 (M27) smart motorway scheme. The scheme is 24km (15 miles), and all links on the M27 between junction 4 to 11 will be upgraded to smart motorway, dual four All-Lane Running. The hard shoulder will be retained between junctions 7 and 8.

The scheme will involve:

  • permanent conversion of the hard shoulder to create a fourth lane and changing the junction slip roads to accommodate this
  • new CCTV cameras and electronic information signs and signals on gantries - these will show variable mandatory speed limits and manage traffic flow and incidents
  • emergency refuge areas throughout the length of the scheme
  • the hardening of the central reserve and installation of a reinforced barrier to improve safety
