M25 junction 28 improvements
Upgrading junction 28 of the M25 between the M25 and the A12 in Essex.
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

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
Our improvements at junction 28 on the M25 look to provide safer and smoother journeys for everyone as they make their way through the junction. This includes non-motorised users, also known as NMUs, such as pedestrians and cyclists.
We’re currently working on our final plans for our upgrades to the NMU route, which includes ways to improve the crossing on the clockwise entry slip.
We’ll share our plans for a more integrated and accessible junction here when they are ready.

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:
- Examining Authority’s report and recommendations to the Secretary of State for Transport
- Secretary of State for Transport’s decision letter and statement of reasons
- Development Consent Order as made by the Secretary of State for Transport
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:
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
- Requirement 3 - Detailed Design Report
- Requirement 4 - Construction Environment Management Plan
- Requirement 5 - Landscape and Ecological Management Plan
- Requirement 6 - Contaminated Land and Groundwater
- Requirement 7:
- Requirement 8 - Drainage Strategy
- Requirement 9 - Archaeological Remains
- Requirement 10 - Traffic Management
- Requirement 11 - Trees protection - Arboriculture method statement
- Requirement 13 - Fencing
- Requirement 16 - Site Specific Plan for Grove Farm
- Requirement 19 - Gardens of Peace Muslim Cemetery
