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
