Progress report

We have been working on our proposals for improving this section of road. We recently held a consultation which gave you the opportunity to give your feedback on the proposed route including the 2 options at Chybucca.

We will take your views into consideration before making a decision on the preferred route; we expect to make this decision in 2017.

The consultation is now closed but you can still view details of the preferred route on our consultation page.

The cost of developing this scheme is part funded by an £8m contribution from the European Regional Development Fund.

What next?

We are currently analysing all of the feedback received from the options consultation. Once this is completed we will publish a report summarising the responses. From this the project team will make recommendations for further development of the scheme.

Subject to the findings of the consultation, a preferred route announcement will be made in spring 2017 and the pre-application stage of the development consent process will begin.

Development Consent Order application

As a local you may have followed earlier versions of this scheme. Some of these will have had different approaches and processes, or been governed by older legislation. This scheme is classed as a Nationally Significant Infrastructure Project (NSIP) under the Planning Act 2008. As such, we are required to make an application for a Development Consent Order (DCO) to obtain permission to construct the scheme. The application will be made to the Planning Inspectorate who will examine the application in public hearings and then make a recommendation to the Secretary of State for Transport who will decide on whether or not the project will go ahead.

We currently intend to make our application by spring 2018. Prior to the application, we will undertake further public consultation on our detailed design proposals.

We have put together a clear guide to the planning process, outlining exactly what happens and when you get can get involved.

Why we need this scheme

This section of the A30 is the main link between West Cornwall and the Isles of Scilly and the motorway network. The route is particularly popular in the holiday periods when traffic flows are typically 25% higher than average. This has a marked effect on journey time reliability. The A30 between Chiverton Cross roundabout and Carland Cross roundabout will be brought up to current standards.

The scheme in detail

The scheme is between the A30 between Chiverton Cross and Carland Cross and includes the roundabouts and junctions of Chybucca, Boxheater and Zelah. There are a number of additional minor junctions that provide connections points to local roads. These will need to be examined. Funding for the scheme has been committed through the government’s Roads Investment Strategy. This cost estimate is based on estimates as part of a study undertaken for the previous scheme in 2002/3. These costs will be refined as the business case and design process progresses, and should not be taken as final costs.


The scheme will:
  • improve safety on the route
  • contribute to economic growth by supporting employment and residential development opportunities
  • improve the road user experience and improve connectivity for the communities either side of the route
