Progress report

The consultation period is now closed for this scheme; we'd like to thank everyone who took part and gave feedback on our proposals. We received over 900 responses and public exhibitions were attended by over 1,800 people, with nearly 90% of those who attended rating the events as positive.

The purpose of the early consultation was to understand the concerns of the local community and road users. We wanted to understand which option gained the most support and to listen to suggestions before any detailed design or preferred route is selected. We received valuable feedback on the route options presented, along with suggestions about the junctions along this stretch of the road. Other issues raised included:

  • environmental impacts
  • other key developments proposed for the area
  • existing rat runs in the area
  • non-motorised user services such as cycle paths
  • improving safety

What's next?

As a public body we have a responsibility to ensure that any emerging plans are considered carefully and that the scheme we develop and the way it is delivered will serve the needs of the region. It's important that we get this scheme right, not just in the short term but for the long term.

We're working closely with Essex County Council, Braintree District Council and Colchester Borough Council to understand the impact of the proposed North Essex Garden Community at Marks Tey.

The proposed development may affect the alignment of the A12 between junctions 24 and 25, but is subject to a Planning Inspectors' decision. This decision is expected to be released in Summer 2018.

If the development goes ahead then we may need to put forward new plans that reconsider the road alignment between junctions 24-25. In this case, we'll consult with those affected, and anyone living or working in the area will have the opportunity to share their views with us.

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.

Aims

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
