A303 Sparkford to Ilchester

Improving the single lane to a dual carriageway on the A303 between Sparkford and Ilchester, part of a programme of improvements to the A303/A30/A358.

Region:  South West
Start date:  TBC
Cost:  £100 to £250 million
Status:  PLANNED
Type:  Major Scheme
End date:  TBC
Programme:  A303 / A358 Corridor improvements

Progress report

We're proposing to make some changes to our application for development consent to upgrade the A303 between Sparkford and Ilchester. We submitted our application for a Development Consent Order (DCO) in July 2018. This was accepted by the Planning Inspectorate in August 2018.

As a result of discussions following the acceptance of the application, we’re now proposing to change the DCO red line boundary of the scheme.

This will result in a small increase in the overall size of the area in which we will be working. We are making this change for the following reasons:

  • We propose to alter the size, siting and layout of our main on-site construction compound, which requires additional land to be added to the land affected by the DCO and which would allow the removal of some of the land currently affected.
  • A change to our proposed accommodation works in order to ensure suitable access to Blackwell Farm is maintained, which requires additional land to be added to the land affected by the DCO.

What's next?

Over the next few months the Planning Inspectorate will make arrangements to carry out an examination of the application. This will be led by an examining authority made up of one or more examining inspectors. The Planning Inspectorate will then have 6 months to carry out the examination.

You can find more information about this process at the Planning Inspectorate’s National Infrastructure Planning website.

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

Aims

The aims of the scheme include the following:

  • capacity: reduce delays and queues that occur during peak hours and at seasonal times of the year
  • safety: improve the safety of the network by providing additional capacity, reducing driver stress and enabling safer access to and from the motorway. It will also improve the non-motorised user routes in the area
  • environment: avoid unacceptable impacts on the surrounding natural and historic environment and landscape and optimise opportunities for enhancement
  • local communities: reduce community severance and promote opportunities for improving their quality of life
  • support economic growth: facilitate growth in jobs and housing by providing a free-flowing and reliable connection between the south east and the south west
  • connectivity: improve the connectivity of the south west to the rest of the UK and improve business and growth prospects
  • resilience: improve journey time reliability and resilience, and provide extra capacity to make it easier to manage traffic when incidents occur

The scheme in detail

Our proposal is for a dual carriageway that starts east of Podimore Roundabout and follows the alignment of the existing A303 to Downhead. Travelling eastwards, the route moves north of the existing A303 single carriageway, allowing the existing road to be retained for use as a parallel local road in this section. The route then rises up West Camel Hill before crossing over the existing A303 at the junction with Steart Hill/Howell Hill. The route then takes a southerly alignment briefly before meeting up with the existing road again to pass between Vale Farm and the MOD signal station at Eyewell/Traits Land.

Finally, the route bypasses the existing Hazlegrove Roundabout to the north through the Registered Park and Garden associated with Hazlegrove House, before tying into the existing A303 Sparkford Bypass.
