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
