Progress report

We are consulting on our proposal to improve the A303 between Sparkford to Ilchester from 26 January 2018 to 9 March 2018. This statutory consultation is your opportunity to express your views on the design of the proposed scheme in advance of our application for planning permission to authorise construction of the project.

Businesses, local authorities, public bodies, road users and the communities and neighbouring areas can all play an important part in the development of the scheme. Your feedback is therefore essential to this consultation as it will enable us to improve the proposal before we submit our planning application.

You can find out more about the consultation and have your say by visiting our consultation webpage.

What next?

Your feedback from the consultation will allow us to make sure we have got the best scheme, or highlight where we still need to make changes, before we make our application for planning permission. View our handy guide to the planning process.

If all goes to plan, we aim to submit our application in mid-2018 and would like to start building the new road in 2020.

Why we need this scheme

The A303/A358 corridor is a vital connection between the south west, London and the south east. While much of the route is a dual carriageway, there are still over 35 miles of single carriageway. These sections act as congestion bottlenecks, particularly in the summer months and at weekends, causing delays to road users travelling between the M3 motorway and the south west and an increased risk of accidents.

This section of the A303 between Sparkford and Ilchester comprises a mix of dual and single lane carriageway, which leads to localised congestion, impacting adversely on journey times and reliability. This section also has a poor accident record as a result of poor junction alignment and visibility, and changes in road type.

We are proposing to dual this single carriageway section. The scheme will reduce congestion, improve journey times and make our network safer for customers.


The scheme will:
  • reduce congestion, improve journey times and make our network safer for our customers
  • support jobs and economic growth at a local and national level
  • minimise adverse impacts on the surrounding natural environment and landscape
