    Upcoming weekend closures for September and October

    We're carrying out deep reconstruction work to the carriageway between junction 9 and 11 on the M27 which will result in weekend closures.  

    The westbound M27 will be closed between junctions 11 (Gosport) and 9 (Whiteley) from 9.00pm on Friday 24 September until 6.00am on Monday 27 September 2021.

    westbound M27 closure

    The eastbound M27 will then be closed between junctions 9 and 11 from 9.00pm on Friday 1 October until 6.00am on Monday 4 October.

    eastbound M27 closure

    Signed diversions will be in place. Drivers heading westbound should leave the M27 at junction 11 onto the westbound A27, to re-join the M27 at junction 9.

    Traffic travelling eastbound should leave the M27 at junction 9 and take the third exit at the roundabout onto the A27 towards Fareham. Drivers should continue on the eastbound A27 and re-join the M27 at junction 11.   

    Congestion is expected so drivers are advised to plan ahead and leave extra time for their journeys. All diversions will be fully signed, and closures are subject to change subject to operational requirements or adverse weather conditions.

    Update - August 2021

    We're in the process of removing the metal barrier in lane one of the M27 and will now be painting road markings between junction 4 and 8 on the eastbound section from Monday 6 September to Wednesday 8 September 2021.

    We’ll be painting road markings between the same section of motorway on the  westbound carriageway from Wednesday 15 September 2021 to Thursday 16 September 2021.

    This work will take place between 9.00pm and 6.00am as the activity requires the motorway to be fully closed. Our apologies for any noise disturbance during this time which we'll try our best to keep to a minimum.

    Update - July 2021

    We are making good progress with the upgrade to the M27, and have committed to implementing the recommendations of the Government stocktake before the scheme opens fully. This means it will include stopped vehicle detection technology.

    We are grateful for everyone’s patience while we complete this work, and we expect the upgrade to be fully open in spring 2022.

    Lane reduction on both carriageways between junctions 7 and 8

    Due to fewer vehicles travelling on the M27 because of Covid-19 pandemic restrictions, we will be temporarily reducing the M27 to two lanes between junction 7 and junction 8 on the westbound carriageway. The reduction to two lanes will take place throughout the day from 6am until 8pm each day, from Saturday 16 January 2021 until Sunday 31 January 2021.

    We will also be temporarily reducing the M27 to two lanes between junction 7 and junction 8 on the eastbound carriageway from 10pm on Friday 22 January 2021 until 6am Monday 1 February 2021 to facilitate daytime sheet piling works.

    Gantry installations

    Road closures to allow gantry installation

    The M27 to the west of the Hamble Bridge between junction 8 (Bursledon) and junction 9 (Park Gate) will be reduced from three lanes to two on the westbound carriageway this weekend in preparation for the installation of a new gantry.

    One westbound lane will be closed between 6am until 8pm on both Saturday 17 October 2020 and Sunday 18 October 2020. The lane reduction will be in place for the safety of our workforce as well as road users. Three lanes will be open at all other times throughout this period.

    This activity will involve a piling rig, inserting interlocking sheets into the soil to enable the installation of gantry sign posts. This work is known as ‘sheet piling’.

    Sheet piling on the M27

    The work was originally planned to take place overnight, but following sheet piling work at a number of other locations, and the impact that this activity can cause to local communities when carried out overnight, the programme has been changed so that this work can take place during the day.

    We provide live traffic information via our traffic pages, local and national radio travel bulletins, electronic road signs and mobile apps. Local Twitter services are also available at @HighwaysSEAST.

    North Fareham footbridge installation

    As we continue to upgrade the M27 between junctions 4 and 11 to modern motorway standards, we will be installing the new North Fareham footbridge, which will be situated between junctions 10 and 11 of the M27.

    The bridge installation will require a full closure of the M27 between junctions 9 and 11 from Friday 4 September at 9.00pm until Monday 7 September at 6.00am. This closure will include access off and onto the M27 at junction 10. Once the footbridge has been installed, we’ll be able to re-open the motorway again.

    The bridge installation is taking place overnight, as we need to install the footbridge as quickly and safely as possible. There is less traffic at night, which allows us to close the motorway with reduced impact for the travelling public, and we need to work through the night in order to allow us to re-open the motorway, as soon as the installation is complete.

    We apologise in advance for any disturbance caused, as the bridge installation may be noisy at times, and we have written to local residents to inform them of this installation in advance.

    The closure dates may be subject to change owing to operational requirements or adverse weather conditions. Diversion routes will be clearly signposted.

    We would advise road users to plan their journeys in advance by visiting the Traffic England website or by following our Twitter feed: @HighwaysSEAST

    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 by visiting our Traffic England website or following our regional Twitter feed.

    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 8pm and 6am the following day under full carriageway closure.

Project information

Overview

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

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
