Project information


The A120 is a key route for the local and national economy. Commuters, freight, residents and businesses suffer daily lengthy delays on this single-carriageway road which costs the country millions of pounds every year.

In March 2020, the government announced details of the second Road Investment Strategy (RIS2) covering April 2020 to March 2025. The A120 Braintree to A12 was one of the ‘pipeline projects’ announced that will undergo further analysis and design work for consideration for potential future investment.

The proposals for improving this stretch road were initially developed by Essex County Council. This project has now been passed over to National Highways and we are currently carrying out a validation exercise of all the work that has been done.

Once completed, the validation will establish if further work needs to be done in order to progress the scheme.

There will be full public announcements as we progress this project, and we will additionally notify statutory stakeholders in line with planning requirements. All historical information on this project to date is available via the Essex County Council website.

The benefits of this scheme are:

  • Improving road safety: The scheme is expected to result in a significant reduction in collisions in this area, including on the existing A120 and the local roads used as ‘rat-runs’ when the A120 road is congested.
  • Improving user satisfaction: The scheme would reduce delays due to congestion, make journey times more reliable and increase the overall transport capacity of the A120 corridor. This would be expected to improve user satisfaction significantly, and this is demonstrated by the key concerns identified by the A120 non-statutory public consultation run by Essex County Council, and a survey of road user concerns run by Transport Focus.
  • Supporting the smooth flow of traffic: The scheme will make journey times more reliable by reducing delays from congestion, reducing the number of collisions and improving the resilience of road network. This will help the A120 corridor to cope with incidents such as collisions, breakdowns, road works and maintenance, and flooding.
  • Encouraging economic growth: The scheme is expected to reduce travel delays, underpin new housing and economic growth, and enable businesses to flourish.
  • Delivering better environmental outcomes: The scheme should give help reduce road noise.
  • Helping cyclists, walkers, and other vulnerable road users: Opportunities for providing new and better road crossings are being considered.
  • Achieving efficiency: The proposed routes would mainly be constructed away from the current A120 road, which helps to make construction schedules more reliable, as less road closures and roadworks are needed to complete the new road. 
  • Keeping the road network in good condition: A new dual carriageway would replace around 9 miles (15km) of the A120 single carriageway which currently needs significant maintenance on its road surface.
