Our ambition is to make improvements along the A12 stretching from junction 19 (Boreham interchange) to junction 25 (Marks Tey interchange).
We made a Preferred Route Announcement in October 2019 confirming our plans for the first section of the scheme, from junction 19 (Boreham interchange) to junction 23 (Kelvedon south).
We held a public consultation on four new route options between junctions 23 and 25 between 21 October and 1 December 2019. These new potential routes will be considered if the proposed Colchester Braintree Borders Garden Community is given the go ahead. If the proposed garden community does not go ahead, we will consider the route options presented in our 2017 public consultation.
Itâ€™s important to ensure that our plans for the A12 meet the future needs of the area. We're now analysing all the consultation responses and thank all those who submitted their views on the route options presented.
Once the position on the garden community is clear, we will announce a further preferred route between junction 23 (Kelvedon south) to junction 25 (Marks Tey interchange).
We're now conducting surveys in the area of the preferred route between junctions 19 and 23, and in the area of the various route options being considered between junctions 23 and 25. There will be a series of temporary lane closures and overnight road closures between junctions 18 and 25 while these surveys take place between November 2019 and April 2020.
Now we have announced our preferred route between junctions 19 and 23, we will continue to develop our designs for that section of the road in more detail.
We're carrying out more surveys and ground investigations between November 2019 and April 2020, involving overnight road closures on the A12 between junctions 18 and 25. For details, please see 'A12 Surveys 2019 to 2020' in the 'Project background' area of the Documents tab below.
We expect to announce our preferred route between junction 23 and 25 in 2020.
Following that, we will hold another public consultation to get feedback on more detailed designs for the overall project (between junction 19 and 25).
In the meantime, we'll continue to engage with our stakeholders and the local community to help us refine the design, before inviting the public to submit further feedback.
In line with other transformative infrastructure projects, the government will be seeking to ensure that the benefits unlocked by the A12 improvements are felt by local communities and are appropriately captured. This includes funding contributions and developer contributions in some cases. We'll be working with local authorities and key stakeholders to appropriately capture value generated and will start the process with conversations in 2020.

Why we need this scheme
The A12 Chelmsford (junction 19) to A120 (junction 25) is part of the strategic road network and supports national and regional economy by connecting Felixstowe and Harwich ports to London. It links the towns of Chelmsford, Witham, Marks Tey and Colchester.
This road struggles to cope with existing peak traffic demands, resulting in delays and reduced speeds. With few available diversions, incidents and accidents result in disruption over a wide area.
Without intervention things will get much worse. Projected growth in population and local development will only increase the pressure on this road.
With this scheme, we aim to:
- make the network safer by closing-off private accesses on the A12 and providing alternative accesses
- improve user satisfaction by reducing congestion related delay and improving journey time reliability
- support the smooth flow of traffic by providing greater resilience to cope with incidents
- encourage economic growth by supporting planning, economic and housing growth in Essex and the surrounding region
- deliver better environmental outcomes by reducing the impact of new infrastructure on the natural and built environment
- help cyclists, walkers and other vulnerable users of the network by providing safer alternative routes away from the A12
If your property may be affected by one of our schemes
Sometimes the development of one of our road improvement schemes creates an impact on the properties of people living along or close to the route of the scheme. There are a number of examples where this may be the case â€“ for instance, the sale value of a property may be adversely affected by the change in the environment around it. This could be because of additional noise from a new road, or a significant change in view from the property.
There are a number of documents that explain your rights in circumstances such as these, and set out examples in which you may be entitled to compensation:
