A30 Chiverton to Carland Cross

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

As part of our 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

Back in August 2018 we submitted our application for a Development Consent Order (DCO) which was accepted for examination in September. Inspectors were appointed to examine our application in January and the examination itself started in February. The examination process takes up to 6 months and will be completed by mid August this year.

You can track the progress of the examination and complete the Registration and Relevant Representation Form by visiting the A30 Chiverton to Carland Cross project page on the Planning Inspectorate’s National Infrastructure website.

What's next?

Once the examination has finished the inspectors will write a report for the Secretary of State which includes a recommendation on whether to refuse or grant the Development Consent Order.

Once the inspectors have sent the report to the Secretary of State for Transport, he has three months to make the decision on whether to grant or refuse the Development Consent Order. This means a decision should be made by mid February 2020. The decision that is made will be published alongside the inspectors’ report on the National Infrastructure Planning website.

If you would like any more information on the process we are going through please visit the National Infrastructure Planning website.

Community matters

While the Planning Inspectorate examines our proposals, we'll be shifting our focus to what we can do for local communities, and the legacy the scheme will leave behind.

The STEAM project

From September 2018, we’ll be launching a schools’ project in the area designed to help children and young people understand science, technology, engineering, the arts and maths (STEAM) in the context of the A30 Chiverton to Carland Cross road scheme.

Through a series of interactive sessions relating to the work of our team (which comprises engineers, designers, environmental and traffic experts, scientists and communications specialists) we hope to bring school subjects to life for students, showing how the things they learn in school apply in the real world.

If you're a parent or teacher interested in finding out more about the STEAM project, please email the project team: A30ChivertontoCarlandCross@highwaysengland.co.uk

Designated funds

We’re currently looking at a number of projects with an environmental and cycling safety focus that we’re planning to deliver over the coming months.

Known as Designated Funds projects, these mini-schemes will be carried out completely separately to the A30 Chiverton to Carland Cross improvement scheme. This means that the outcome of the Planning Inspectorate examination will have no bearing on the delivery of these projects.

You can find out more about these projects, including how they're funded, approved and delivered by visiting our Designated Funds page.

Why we need this scheme

Improving the A30 between Chiverton and Carland Cross is incredibly important for Cornwall’s future. It's 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.

This summer we carried out research to gather insight on how it feels to travel to, from and around Cornwall during peak season. Some of our visitors' experiences are captured in this video.

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


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

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.

    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

    Good afternoon, this is Karl Sullivan, Assistant 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.

  • KS_Highways_England

    It looks like everyone is out enjoying the summer holidays today so I’ll look to close it there. Keep an eye on the website for the dates of the next web chat and other events that we are attending in Cornwall. Remember if you have any questions you would like asked you can still email us on A30ChivertontoCarlandCross@highwaysengland.co.uk.
    Have a great weekend!

  • Colin Sawmy

    Good afternoon,
    I’ve always thought this scheme was a long time coming; so well done for what looks a carefully thought out plan. However, there’s one future problem that you may not have considered: By making Chiverton Cross clear of holdups, and having a dual carriageway all the way from Exeter, traffic is then going to stop dead at Hayle. This is already a problem in the summer, with long queues backing up. I suspect the new scheme will exacerbate the problem. In fact, every time you clear a problem area with a new scheme, the traffic will be a problem at the next major junction. I don’t mind as I live outside Truro – but I suspect those further down the line will soon be complaining!

    • JH_Highways_England

      Hi Colin,

      Thanks for getting in touch. It’s a good point you have raised, and is something we are mindful of. As you will know, the opening of the new Temple to Higher Carblake scheme last summer transformed that section of the A30. Although this has had an impact on the approach to Carland Cross, as traffic is forced to slow down and filter on to the single carriageway road – the impact has not been as severe as some expected.

      The A30 Chiverton to Carland Cross scheme is likely to have a similar effect, although a lot of traffic does leave the A30 prior to Hayle, it is not going to make the current situation any better in the short term. It is important to recognise that large road schemes take a long time and it is impossible to relieve all congestion in one go. There is a long term ambition to upgrade the whole A30 from Exeter to a consistent Expressway standard.

      Thanks Again for getting in touch,


  • JH_Highways_England

    Good afternoon, this is Josh Hodder, Project Manager for the A30 Chiverton to Carland Cross scheme. I will be available until 3pm to answer any questions you have about the project, or the next steps of the planning process.

  • Sally Ann

    Hi Josh, just wondering what the next steps are for the project? And when will we they be happening?

    • JH_Highways_England

      Hi Sally,

      Thanks for getting in touch. We have now submitted our application for a Development Consent Order to the Planning Inspectorate. They have 28 days from today to accept the application, and once that happens the formal process will begin. At the moment, we are expecting a final decision towards the end of 2019, and plan to start on site early in 2020.

  • Josh Catchpole

    I run a business in Cornwall, how are your improving journey times on that road? How will it impact my business?

    • JH_Highways_England

      Hi Josh,

      Thanks for the message, the new road will reduce journey times. But more importantly, it will increase journey time reliability. This will mean that no matter what time you leave, you will be able to have the confidence in the time it will take for you to arrive. As a business operating in this area, this makes planning and operating much more efficient.

  • JH_Highways_England

    Hi Kimberley,

    Thanks for your message. As with any road scheme, there will be an element of disruption. However the benefit of this project, is that the road will be predominantly “off-line” or away from the existing road. The level of disruption will depend on the stage of the project, where we need to connect into the existing road or realign roads there will be diversions in place. We are committing to keep two way traffic flowing on the existing A30 for the duration of the works, although there may be speed restrictions in place where narrow lanes are required.

  • JH_Highways_England

    Hi Danny,

    Thanks for your message. As with any large infrastructure scheme, there are always going to be impacts. However we have been working very hard to make sure these are mitigated as best as possible. Once the Planning Inspectorate upload our application on to their website, you will be able to view the full Environmental Statement online. This should happen within a week and will provide full details on the impacts and mitigation measures.

  • JH_Highways_England

    Thanks to everyone who got in touch. Have a great weekend. If you would like to find out more about the scheme or have any questions, please don’t hesitate to contact the project team A30ChivertontoCarlandCross@highwaysengland.co.uk
