    Planned closures for January 2022

    Weekend closure 21 January to 24 January - westbound junctions 11 to 9

    We’re continuing to make good progress with the M27 junctions 4 to 11 motorway upgrade scheme. We need to complete some essential maintenance work on the westbound carriageway between junctions 11 and 9. This includes reinstating manholes in the carriageway, resurfacing, carrying out surveys of the drainage network, white lining and installation of the studs that sit between the lanes. To do this safely, we’ll be closing the westbound carriageway between junctions 11 and 9 from 9pm on 21 January 2022 until 6am on 24 January 2022.  

    We’re unable to complete these activities during a standard overnight closure, and as a result a full weekend closure is required. During this time, we’ll take the opportunity to undertake as many additional activities as possible.

    During the closure, a signed diversion will be in place via the A27:

    Surfacing work in January

    We’ll also be continuing with surfacing work during January. We carry out this work overnight or at weekends to try and minimise the impact on road users.

    We complete this work in sections, and the details of January’s closures are listed below. All closures will be from 9pm until 6am the following morning.

    Safety barrier improvements - junction 11 westbound exit slip

    You may have noticed some delays recently on the M27 westbound as you approached the exit at junction 11. We’ve been carrying out some improvements to the safety barrier on the slip road. And to help keep everyone safe, we needed to reduce the slip road from two lanes to one.

    The slip road was fully reopened on 21 December and we’d like to apologise for any disruption this essential work has caused. Thank you to everyone for your patience and understanding.

    Weekend Closure on M27 near Fareham

    Road users are advised to plan ahead if they are intending to use the M27 at the end of October, due to a weekend closure between junctions 9 and 11. 

    The M27 will be closed between junctions 9 and 11 from Friday 29 October to Monday 1 November, in order to carry out deep reconstruction works. This work was due to take place earlier in October, but was postponed due to bad weather.
      
    The eastbound M27 will be closed between junctions 9 and 11 from 9.00pm on Friday 29 October until 6.00am on Monday 1 November, to allow for the re-scheduled work. 

    Signed diversions will be in place throughout the weekend closure. 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.
       
    Please be advised that junction 9 will remain open throughout and shoppers can still access the Whiteley Shopping as usual during this time.
     
    Our apologies for the disruption or congestion these works may cause. Please do plan ahead and leave extra time for your journey and check our National Highways live traffic information on www.highwaysengland.co.uk/traffic.  You can also check local and national radio travel bulletins, electronic road signs and mobile apps as well as our twitter feed 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 

Project information

Overview

The M27 motorway upgrade 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) motorway scheme. The scheme is 24km (15 miles), and all links on the M27 between junction 4 to 11 will be upgraded to four lanes. 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
