Region:  South West
Start date:  2019/2020
Cost:  £100 to £250 million
Status:  PLANNED
Type:  Major Scheme
End date:  2022/2023

Progress report

We recently asked for your views on our proposals for the new route from Chiverton Cross to Carland Cross. This included two options at Chybucca: Option A and Option B. This consultation is now closed.

We are carrying out ground investigation works to analyse the environment, ground levels and local geology. This work will last around 10-12 weeks and will help us further develop our proposals. We will also carry out environmental surveys at various times throughout 2017.

During the work you may see 4x4 vehicles, drilling equipment or excavation machines at work. The land we survey will not necessarily be impacted by the construction of the final scheme.

What next?

We will analyse your feedback and create a report summarising this and outlining our response. This, along with further technical and design work, will help us take a decision about our preferred route. We hope to take this decision in spring 2017.

Some of you may have followed earlier versions of this scheme. Legislation has since changed so we have put together a guide to the planning process. This outlines exactly what happens and when you get can get involved.

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

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
