Progress report

We have completed the first stage of this project, with initial wildlife and habitat surveys now complete. In December we completed a round of forums to engage with stakeholders such as local MPs, businesses and environmental organisations.

What next?

We are currently assessing design options that will meet the aims for this scheme. Your views at this early stage of scheme development are important to us and we will be starting a public consultation on Monday 23 January 2017. Further details, including an online questionnaire and a list of public exhibition venues and dates will be uploaded to this webpage on Monday 23rd January 2017. We will combine your feedback with further technical assessment to determine our “preferred route”: the option we will recommend to the Planning Inspectorate.

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 between junctions 19 and 25.

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.

Essex County Council is leading a feasibility study for long term improvements to the A120 between Braintree and A12. For more information about the scheme, please visit the Essex County Council website.

Aims

With this scheme, we aim to:
  • reduce congestion and delays
  • increase road capacity
  • improve journey time reliability
  • supports the growth identified in Local Plans
  • improve safety
  • provide alternative access to local roads
  • help the transport network to better cope with road maintenance and with incidents such as collisions, breakdowns, maintenance
  • improve the environmental impact of transport on communities along the existing A12 route
  • reduce the impact of new infrastructure on the natural and built environment
  • provide improved routes between communities for cyclists, horse riders and pedestrians
  • reconnect communities
  • improve safe and effective access for public transport users
  • improve road user satisfaction
