An eight-mile stretch of the A30 between Chiverton and Carland Cross will be improved if proposals go ahead, with roadworks expected between 2019/20 and 2022/3.

Highways England say that this will help to improve journey times and unlock one of the last bottlenecks in Cornwall.

The cost of developing the scheme is being partly funded by an £8 million contribution from the European Regional Development Fund, with an additional £12 million for the construction phase. The remainder of the cost of developing and delivering the scheme will be funded by central government.

Sarah Newton, the Conservative MP for Truro and Falmouth, said: “Upgrading this stretch of the A30 will bring significant benefits for residents, businesses and visitors, cutting congestion and boosting the local economy.

“I discussed the plans with the Transport Secretary during his recent visit to Cornwall and I’m keen to ensure local residents fully understand the proposals and have their say.

“I would encourage people to find out more, either at Camborne Show or by taking part in the live web chat.”

After opening the plans up for public consultation earlier this year the company is now continuing its community engagement, attending the Stithians Show on July 16 and the Camborne Show on July 21. It will also be participating in live web chats with the next one planned for this Friday, (July 27).

Project Manager Josh Hodder said: "We were at the Golowan Festival in Penzance last weekend and received plenty of interest from both communities local to the scheme and holiday-makers, and we are keen to keep communities updated on our plans.

"Since consultation, we have been progressing with details of the design, working to reduce impact on the environment, and continuing our engagement and discussions with local communities.

"I’d urge anyone with an interest to come and chat with us to find out more and answer any questions they have."

Highways England is now finalising the details of the scheme before submitting its planning application in late summer at which point people will also have the opportunity to register with the Planning Inspectorate to have their say.
