    Diversion of existing cables

    There’s a number of cables and pipes that run underneath and near our roads, with one of these being the NRTS (national roads telecommunications services). These fibre optic cables connect to cameras on our roads, so we can monitor and manage traffic levels or incidents.

    As part of our scheme, we’ll need to divert these cables, so that they’re in the right place when we start our main construction work in October.

    In order to move these, we’ll need to put some lane closures in place on the following roads:

    • inside lane of the M25 junction 28 clockwise exit slip
    • inside lane of the M25 junction 28 anti-clockwise exit slip
    • inner ring lane of the M25 junction 28 roundabout
    • the M25 anti-clockwise hard shoulder between junction 28 and 27

    The lane closures will be in place between 10pm and 5am on:

    • Monday 8 August
    • Tuesday 9 August
    • Wednesday 10 August
    • Thursday 11 August
    • Friday 12 August
    Ground and Archaeological Surveys

    Our teams are currently undertaking a number of surveys, in order to collect as much information about what is above and below the ground as possible. These help us know where utility pipes and cables are, geological information such as ground conditions and also helps us mark out where the new bridges and structures will go.

    We’ll soon be carrying out archaeological surveys, as there is a historically significant former airfield, Maylands Aerodrome, within our site. The airfield is considered as the birthplace of the UK package holiday industry and had notable pilots, such as Amy Johnson and Jim Mollison, once flying from the strip.

    Local heritage groups will also be on hand to help us uncover and record any possible discoveries we make.

    Our Information Portal is also open, where you can find out more details about the scheme, what we’ll be doing and when, as well as a fly through video of how the scheme will look once finished.

    Start of Preparation Works

    We’ll soon be starting to get the site prepared, ahead of main construction in October this year.

    You may notice increased activity on site from the end of July, as we carry out the following activities:

    • clearing the site of vegetation
    • installing a compound to provide facilities for the teams on site and a place to store materials
    • carrying out ground and archaeological surveys
    • Cadent Gas diverting a gas mains

    Most of our construction will be taking place off network but don’t worry, we’ll be posting regular updates here, including information about any closures. You can also sign up to received updates straight to your inbox, just click ‘Sign up to updates’ on the right of this page.

    Our Information Portal is also open, where you can find out more details about the scheme, what we’ll be doing and when, as well as a fly through video of how the scheme will look once finished.

    Overnight lane closures on A12

    We’ll be setting up a site compound to provide welfare facilities and store materials during construction. The access to this compound will be off the A12 eastbound near the Maylands Golf Club entrance.

    For us to build the access and track to the compound site, we need to temporarily close a lane on the A12 eastbound between Woodstock Avenue and the A12 exit slip, heading towards M25 junction 28.

    This will take place overnight (between 10pm and 5am) on the following dates:

    • Wednesday 27 and Thursday 28 July
    • Monday 1 and Tuesday 2 August

    Access to Woodstock Avenue, Maylands Golf Club and the A12 exit slip will be unaffected during the closures.

    Development Consent Order given the green light

    Today we welcomed the Secretary of State for Transport decision to grant us a Development Consent Order, which allows us to proceed with our proposals to improve the M25 junction 28.

    At peak times up to 7,500 vehicles per hour pass through this heavily used junction, resulting in queues and delays. Improving the flow of traffic around this junction and allowing more capacity on the exit slip roads, will provide a safer and more integrated network for everyone. There will also be less likelihood of traffic queuing back onto the M25 due to the reconfiguration of the junction.

    Thank you to everyone for their engagement and contribution in the development of the scheme to date.

    To make sure you know what’s coming up, sign up to our project newsletter using the sign-up link below, we’ll also be providing regular updates on this page.

    You can view more information about the decision on the Planning Inspectorate website.

    Keeping you informed

    We plan to start preparation work this summer, with main construction starting this autumn. To make sure you know what’s coming, and to keep everyone up to date, we will:

    • issue regular project newsletters – you can join the mailing list by signing up on this page
    • run online briefings in summer 2022 to provide the opportunity to ask the team any questions
    • organise face-to-face events using our engagement van at local venues. These will provide information about the scheme and allow us to answer any questions you and others may have. We will provide you with more details of these on this page soon.

    Development Consent Order decision date delayed

    The Secretary of State for Transport has asked for more time to make a decision on whether we can continue with our proposals to improve the M25 junction 28.  

    In his statement, the Secretary of State sets out he is extending the deadline to 16 May 2022 to allow for further consideration of environmental matters.

    We’re committed to delivering the improvements at M25 junction 28 and remain confident that our proposals will deliver much needed additional capacity, with better connectivity for people and business, and safer journeys for everyone. At peak times up to 7,500 vehicles per hour pass through this heavily used junction, resulting in queues and delays.  

    Thank you to everyone for their engagement and contribution in the development of the scheme to date. We will continue to work with the Planning Inspectorate, local stakeholders and local authorities until the Secretary of State makes his decision.

    Further information regarding the extension and any additional consultations will be posted on the Planning Inspectorate’s website.

    Scheme prepares for Secretary of State decision

    The Development Consent Order (DCO) examination for our improvements at M25 junction 28 was completed in mid-July.

    The planning inspectorate has also completed its report, which has now been submitted to the Secretary of State for Transport, for his consideration. This report is not made available until a decision is announced by the Secretary of State.

    We’re expecting a decision later this year and, if we get the go-ahead, we would look to start work in spring next year.

    We’ve awarded a contract to GRAHAM to build the scheme. Until we receive the Secretary of State’s decision we’ll be carrying on with the detailed design and planning how to build the scheme. We’ll hold public events to provide more information about how we will deliver the scheme before we start any work.

    Don’t forget to sign up to our newsletter on the right-hand side of this page to stay up to date with the project.

    M25 junction 28 – what’s happening?

    The Examining Authority are currently undertaking an independent examination. They are assessing the important and relevant issues along with the initial views of the ‘Interested Parties’ of the proposed improvements to the M25 junction 28. The Examining Authority will then issue an initial assessment of the issues that they would like to examine along with a draft timetable for the examination.

    A ‘Preliminary Meeting’ will then be held, and due to the current restrictions around public events, this meeting could be online and take place over a couple of days.

    Following this meeting a final timetable will be issued and the six month ‘Examination’ period will start. During the examination period, hearings will take place where ‘Interested Parties’ are invited to provide more details of their views in writing and the Examining Authority will ask their written questions. All documents received and issued by the Planning Inspectorate will be published on the Planning Inspectorate webpage.

    Following the examination, the Examining Authority will then prepare a report to the Secretary of State for Transport, including a recommendation about whether to grant or refuse development consent. Within three months of the close of the examination, the report will then be sent to the Secretary of State and is not published until the decision is made.

    The Secretary of State then has 3 months to make a decision to grant or refuse development consent. Both this decision and the Examining Authority’s report will then be available on the Planning Inspectorate webpage.

    We submitted an application for a Development Consent Order (DCO) on 27 May 2020 and it was accepted for examination on 24 June 2020. All documents relating to the DCO, including the application form and accompanying documents, drawings, plans and maps and the Environmental Statement can be viewed electronically and free of charge on the Planning Inspectorate webpage. Alternatively, you can view these documents at either Brentwood library or Essex library.

    Give your views on the scheme

    There will be a six-week representation period followed by further time to arrange the examination, before the formal six-month examination period can start. During the examination, the Planning Inspectorate will issue requests for further information from us and other parties to be provided in writing. They also will facilitate a series of public hearings.

    To contribute to this process, you will need to register as an Interested Party once the representation period opens and make a Relevant Representation outlining your views to the Planning Inspectorate. The Planning Inspectorate need to receive this during the representation period. We will carry out targeted publicity about the representation period when the arrangements including dates are finalised. You also can receive updates on the scheme from the Planning Inspectorate, including confirmation of when you can submit a Relevant Representation, by signing up to scheme updates on the Planning Inspectorate webpage for the scheme.

    The Planning Inspectorate website has an advice note which outlines how the general public can get involved including how to submit a Relevant Representation in order to become an Interested Party.

    Application for Development Consent Order

    Our proposals for the M25 junction 28 improvement scheme are the subject of an application for a Development Consent Order (DCO). We are applying for a DCO to give us the planning permission and legal powers we need to build the scheme. We have submitted our application to the Planning Inspectorate, the government agency responsible for operating the planning process for DCOs. Our DCO application was accepted by the Planning Inspectorate on 24 June 2020 for formal examination.

    You can view our application on the Planning Inspectorate website.

    Supplementary consultation now closed

    Our supplementary consultation on the proposed changes and newly identified impacts of the scheme closed on 2 December at 11.59pm. You can still view all of the information about our proposals in the 'Project media files and documents' section below.

    We would like to thank those who got involved, as we begin to review, consider and analyse your feedback.

    This scheme is categorised as a Nationally Significant Infrastructure Project under the Planning Act 2008. As such, we're required to make an application for a Development Consent Order (DCO) to obtain the necessary approvals to construct and operate the scheme.

Project information

Overview

The M25 junction 28 plays a huge role in connecting the A12 and the M25, as well as providing access to Brentwood via the A1023. Up to 7,500 vehicles pass through the junction roundabout at peak times.

As it is operating at capacity, vehicles using the junction face congestion and delays, which effects local air quality. Our research shows that traffic is expected to increase in the area by around 30% by 2037, which means that over 9,000 vehicles could be passing through it by this date.

Our improvements include:

  • building a new two-lane loop road, for traffic travelling from the M25 anti-clockwise onto the A12 eastbound (towards Brentwood). This will include the construction of new bridges to take the loop road over or under the other road links, and the Weald Brook; new signage and changes to the landscape
  • changing the position of A12 eastbound exit slip road and M25 anti-clockwise entry slip road to allow for the new loop road
  • widening the M25 anti-clockwise carriageway to provide more space for traffic leaving for the A12 eastbound

To find out more about our scheme visit our information portal.

Our improvement scheme will:

  • Increase capacity and reduce congestion at the junction and on the approaches and exits
  • Improve safety by redesigning the existing roundabout layout and reducing traffic levels
  • Provide better connections between the M25 and A12
  • Reduce annual collision rates through additional capacity
  • Improve average journey times and reliability for all passing traffic through the junction
  • Minimise the impact of air and noise pollution in the local area by smoothing the traffic flow
  • Reduce traffic queuing back onto the M25
  • Help economic growth in the area by providing improvements to cater for future traffic demands

We’ll start our preparation work in summer 2022, with main construction starting in October 2022. Our scheme is expected to be open for traffic in summer 2025, with planting and landscaping continuing off network for a short time afterwards.

Most of our construction will take place off the road network, with the new loop road and links being almost fully built before we need to do any major work that will impact drivers. 

You can find out more about what work is happening, and when, on our construction timeline.

Documents

The Development Consent Order (DCO) process was established by the Planning Act 2008 and is used for certain large and complex schemes (including highway improvements) that have been designated as a Nationally Significant Infrastructure Project (NSIP) by the Government.

The Secretary of State for Transport granted the Development Consent Order (DCO) for the M25 junction 28 improvements on 16 May 2022. Links to key DCO documentation can be found below:

You can view our full Development Consent Order application on the Planning Inspectorate website.

This includes documents identified under Article 43 and Schedule 9 of our Development Consent Order, which have been certified as true copies by the Secretary of State.

Development Consent Order – Requirements Register

Requirements are conditions that have been included in the DCO, which control how the project must be implemented (constructed and maintained). Implementing the DCO in accordance with these conditions involves completing consultation and approval processes that have been defined in the DCO. These processes are referred to here and in the DCO as “discharging” the requirements.

This Requirements Register is a live document and will be updated as the process to discharge the requirements progresses.

The latest version will always be published below:

View the Requirements Register.

This register will be maintained for three years following completion of the project. The register sets out:

  • each requirement
  • whether the requirement needs approval by the Secretary of State (or other duty holder)
  • whether any approval has been applied for or given
