M27 junctions 4 to 11: smart motorway

We're 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:  January 2019
Cost:  Â£244 million
Status:  CURRENT
Type:  Major Scheme
End date:  2020-21
Programme:  

Progress report

Traffic Management Switch

We will be continuing with the switching of our traffic management from the central reserve to the verges of the M27 from junction 9 to junction 11. When complete, the switch will allow us to work safely in the verges beside the motorway, while allowing road users to continue to use three lanes in both directions during the day.

The traffic management switch between junction 9 and junction 11 will re-start on 29 June 2020 and is expected to end on Monday 6 July 2020. All work will take place overnight, between 8.00pm and 6.00am the following day under full carriageway closure.

Bored Piling

We will be undertaking preparatory works to accommodate the installation of new gantries between junction 4 and junction 11.

This activity will take place at 23 additional locations between junction 4 and junction 11 from 29 June 2020 to 10 August 2020. Bored piling will now be undertaken overnight between 8.00pm and 6.00am the following morning due to operational requirements which don’t enable bored piling and earthwork activities to take place at the same location during the same day.

Further closures will be required for bored piling activities, and we will communicate these when the dates are confirmed.

All dates may be subject to change owing to operational requirements or adverse weather conditions. We advise you to plan your journeys in advance. For up to date details of closures, see the planned roadworks feed. You can also keep up to date by visiting our Traffic England website by following our regional Twitter feed.

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's 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
