Status:  PLANNED
Type:  Major Scheme
End date:  2022/2023

Progress report

On 3 July 2017 we announced the preferred route for the A30 Chiverton to Carland Cross improvement scheme. The preferred route provides a new dual carriageway running to the north of the existing A30 between Chiverton and Chybucca and to the south between Chybucca and Carland Cross. The existing A30 will be kept to provide a local route. The announcement of the preferred route follows a comprehensive review of options and extensive analysis of the responses to our 2016 public consultation. We have considered responses very carefully and carried out further assessment of the options before making our decision. We would like to thank everyone who contributed to our consultation last year and helped to influence this decision. For more information on the outcome of the consultation and details of the preferred route you can visit our consultation webpage.

What next?

We are still at an early stage of the project. The preferred route announcement paves the way for the next stage of development. We will progress the design and assessment of the preferred route in more detail, as well as carry out environmental surveys, more detailed air quality and noise impact assessments, further traffic modelling and design. We are currently conducting surveys as part of our work for the scheme, which are an important part of understanding the environmental and physical constraints of the area to help inform design decisions. We understand that a major new infrastructure project on this scale can cause worry and concern, particularly about the affect it will have on homes, communities and the environment. We are contacting land and property owners close to the route to help them understand potential impacts, their options and their rights and have prepared a number of land and property documents for guidance. These are available to view in the media section. There will be further opportunities to comment on the proposals we put forward and further public consultation. This is an integral element of the statutory planning and consenting process.

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
