A30 Chiverton to Carland CrossRecently updated

Upgrading the A30 single carriageway between Chiverton Cross and Carland Cross roundabouts.

As part of Highways England’s Strategic Road Network, the A30 is a road of strategic importance, which is why an £8m contribution from the European Regional Development Fund has been committed, as well as being identified as part of the Government’s Roads Investment Strategy.

Progress report

Our statutory consultation on the A30 Chiverton to Carland Cross dualling scheme closed in March 2018. We had over 800 responses from local people, organisations and businesses. We’d like to thank everyone who participated in the consultation, using the opportunity to speak to the project team and share their feedback on the proposal. We are now considering all the responses very carefully before moving on to the next stage of the scheme development.

We recognise that as the scheme progresses you may continue to have questions for us. To respond to this we will be hosting regular web chats from 1pm until 3pm on the last Friday of every month. If there is anything you want to ask us, please feel free to log on at the foot of this page on the last Friday of every month, submitting your questions. We’ll try to answer as many as possible during the allotted time.

Our next web chat will be held on Friday 31 August, between 1pm and 3pm.

We'll also be attending a number of community events and festivals in the coming weeks and months, which you can find more details about on our Community News section. Do come and find us at these events if you would like to talk to the project team in person.

For more details about our progress, you can read our latest newsletter.

What next?

We've analysed the responses from the public consultation, which we're using in combination with the results of ongoing surveys to produce a consultation report. This will detail the responses we received as part of the consultation, whether these have resulted in a change to the scheme, and if not, why not. The consultation report will be used as part of our application for a Development Consent Order (DCO) for the scheme, which we intend to submit to the Planning Inspectorate later this summer.

A DCO is a special type of planning application, which is needed for a Nationally Significant Infrastructure Project (NSIP). Following the submission of the DCO application, the Planning Inspectorate will hold a public examination before making a recommendation to the Secretary of State for Transport who will decide whether or not the project should go ahead.

Why we need this scheme

Improving the A30 between Chiverton and Carland Cross is incredibly important for Cornwall’s future. It is the only remaining stretch of single carriageway on the A30 between Camborne and the M5 at Exeter; journeys on this part of the road are regularly delayed, congestion often brings traffic to a standstill, and as a result the Cornish economy is being held back.

For local people, particularly during the summer season, the simple act of getting to a neighbouring village can lead to unacceptably long and unreliable journeys, while opportunistic rat runners pose increased risk of accidents in their villages.

You can view our fast facts document to find out more.

The scheme in detail

The Government’s Road Investment Strategy includes a commitment to improve the A30 between Chiverton Cross and Carland Cross roundabouts to dual carriageway standard. Funding for this scheme includes a contribution from the European Regional Development Fund of £8 million towards its development costs, with a further £12 million allocated for the construction phase.

Our proposal includes:

  • an 8.7 mile, high quality 70mph dual carriageway, connecting to the existing A30 dual carriageway at either end
  • replacement of Chiverton Cross roundabout with a new, two-level motorway style roundabout
  • a new, two-level partial junction at Chybucca, with west-facing slip roads connecting to the new dual carriageway
  • replacement of the existing roundabout at Carland Cross with a two-level motorway style junction
  • new bridges and accesses across the new road and the old road
  • retention of the existing A30 for local traffic

You can find more information about the proposal on our consultation page.

We had over 800 responses from local people, organisations and businesses to our recent consultation. Consultation feedback highlighted a number of themes including the need for east facing slip roads at Chybucca and a request for a new cycle route at Chiverton Cross junction. We're considering this feedback along with other responses as part of our assessment and design development ahead of submitting our planning application.


The objectives of the scheme are to:

  • reduce congestion
  • unlock growth
  • connect communities
  • improve safety, operation and efficiency
  • protect the environment
  • minimise disruption during construction

    Good afternoon, this is Josh Hodder, Project Manager for the A30 Chiverton to Carland Cross. I will be available until 3 pm to answer any questions you may have about the scheme and the process moving forwards.

  • Pippa Gibbs Joubert

    If the scheme goes ahead, when will it open? Thanks, Pippa.

    • JH_Highways_England

      Hi Pippa, thanks for your message. Subject to statutory approval through the upcoming planning process, we are working towards starting construction work in March 2020, opening to traffic towards the end of 2022. The overall completion of the scheme is due in 2023.

  • Jacob Matthews

    Hi, please can you explain why you don’t just widen the existing road?

    • JH_Highways_England

      Hi Jacob, thanks for your question. In the very early stages of the scheme this option was explored. It was discounted for a number of reasons, including businesses and properties along the route requiring access, the vertical alignment of the road being of a standard incompatible with a modern dual carriageway in terms of safety and the potential impact of construction activities on the local community. A real advantage of a new “off-line” route is that it provides resilience and separates local traffic from the strategic road network as the old road will be retained.

      • Jacob Matthews

        Thanks for the response, it’s good to hear you think about the properties and businesses.

  • Laura

    I dont understand why you have to move Chiverton Cross, why can’t you build the junction where it is?

    • JH_Highways_England

      Hi Laura, thanks for your question. The size and layout of the new junction has been designed to meet forecast demand, as well as modern safety standards- for this reason it is much larger than the existing roundabout. To accommodate the new junction in the existing location would mean a number of businesses and local properties would be significantly impacted, to the point of potential demolition. In addition to this, the existing junction is in close proximity to the Cornish Mining Landscape (World Heritage Site) which may sustain adverse visual impacts from the new junction.

      During construction of the new junction the existing junction will be able to function, whereas to replace the existing roundabout would effectively close the A30 from Chiverton Cross to the west for a significant period of time. All this is taken into account during the decision making process.

  • JH_Highways_England

    Hi Suzy, thanks for getting in touch. You weren’t alone in your request, and we have taken feedback from the cycling community very seriously. Since the consultation earlier this year, we have made a number of small changes to the design to improve connectivity and safety for walkers, cyclists and horse riders. Not only have we made changes to Chiverton Cross junction to help address concerns, but we have also made some minor changes along the rest of the route. Our full and final plans will be published on submission of our application for a Development Consent Order later in the summer of this year.

  • JH_Highways_England

    Hi Harry, thanks for your question. You are right, it’s certainly been a long time coming. Over ten years ago the scheme was put on hold due to funding cuts, and the congestion has become progressively worse over the years.

    This scheme was announced in the Government’s Road Investment Strategy 2015-2020 and although there are never absolute guarantees of a scheme’s completion until permission has officially been granted, the case and support for the scheme has so far been extremely strong, with analysis of feedback at non-statutory consultation indicating that over 95% of respondents were supportive of the scheme.

    It is widely acknowledged that the region is heavily dependent on tourism. Making the region feel more accessible could also make it more investable for business more widely – economic analysis of the scheme’s value for money indicates that for every £1 invested in the scheme, it’s likely to return between £3 and £4.

  • Kirsty Browne

    Hi. I would love for someone to come and chat to us. We live on land that will be compulsory purchased. We have for the last 10 years but as an adjoining property as this is our sons inheritance and our future home we would love to know where to stand

    • JH_Highways_England

      Hi Kirsty, thanks for getting in touch. We will be more than happy to come out to talk to you. It can be a worrisome time for people like you who are directly affected by our proposals. Please drop an email to the scheme inbox (A30ChivertontoCarlandCross@highwaysengland.co.uk) with your details and we will arrange for a member of team to come and see you.

      • Kirsty Browne

        Thank you I will

  • JH_Highways_England

    Hi Andy, thanks for your question. and I’m glad you approve of our proposals. Highways England are responsible for the A30 as it forms part of the Strategic Road Network, but Cornwall Council are the Highway Authority for the operation and maintenance of the A390. Although we are working closely with Cornwall Council in the development of the A30 scheme, I don’t have any information to hand on the latest A390 plans I’m afraid.

    • Andy Kelly

      Great, Cornwall Council…. think I’ll be using chybucca to get into Cornwall, assuming you can still use Chybucca without a huge detour coming from Tuckinmill…?!?

      • JH_Highways_England

        Hi Andy, yes from the west you will be able to get off at either Chiverton Cross or Chybucca to access Truro. The main benefit for you will be the removal of Chiverton Cross junction (number 1 accident spot in the whole of Cornwall!) and a continuous high quality dual carriageway until you get off the A30. This will result in reduced journey times, but more importantly a consistent journey time and a much safer journey.

  • JH_Highways_England

    Hi Spud, thanks for your comment. Feedback from the consultation would suggest you are not alone in your views!

  • JH_Highways_England

    Hi Suzy, the short answer is yes. We intend to hold some events locally at or around the time of our application submission to explain the key changes to people and provide information about the process moving forwards. Further information about this will be released over the coming weeks.

  • JH_Highways_England

    Thanks to everyone for taking the time to get in touch. We will be holding another web chat next month on Friday 27 July. In the meantime, if you would like to get in touch with a question or would like to find out more about the scheme, please email A30ChivertontoCarlandCross@Highwaysengland.co.uk.
    Have a great weekend and enjoy this glorious weather!

  • KS_Highways_England
