Progress report

We held a public consultation on our proposed options from 15 February to 28 March 2017. This was to provide you with the opportunity to give your views on our proposals. You can still visit the consultation page to read the consultation documents.

We are now carrying out habitat surveys, gathering evidence of any potential protected species residing within the area. Ecologists will be conducting a range of surveys, both day and night.

During the work you may see you may see members of the ecological team studying trees, hedges, barns and ponds for protected wildlife. The land we survey will not necessarily be impacted by the construction of the final scheme.

What next?

We will combine your feedback from the consultation with further technical analysis and use this to decide our “preferred route”, the option we will take forward for more detailed design. We hope to be able to announce the preferred route in autumn 2017.

If all goes to plan we would like to start on site 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.

Aims

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
