National Highways is reminding drivers to plan their journeys ahead of this weekend’s A30 road closure in Cornwall.

As part of National Highways’ A30 Chiverton to Carland Cross road upgrade, the A30 will be closed between the temporary Chiverton interchange and Boxheater from 8pm on Friday, July 14 to 6am on Monday, July 17, and overnight next week between the temporary Chiverton interchange and Carland.

The work will see the last major closures until after the summer holiday period, and will enable a series of road tie-ins and major earthworks to be carried out.

During the weekend closure, all traffic will be diverted via the B3285 and the A3075.

During the following week, the A30 will also be closed overnight on weeknights from Monday 17 to Friday, July 21.

This will be for the next major milestone for the project as a new temporary link from Carland Cross to the A30 is introduced to prepare for the construction of a flyover later in the year as part of the new junction. The work will also see the removal of a plant crossing point across the A30.

During the weeknight closures, the A30 will be closed between the new Chiverton interchange and Carland Cross from 8pm to 6am each night, and from 9pm on the Friday.

All through traffic will be diverted via the A3076/A3058 and the A3075. And local traffic will be able to use the A39 to and from Truro as usual.

Neil Winter, National Highways’ Senior Project Manager for the A30 scheme, said: “We need these weekend and overnight closures to progress vital work along the whole route before the start of the summer holiday.

“We acknowledge these closures will have an effect on people’s journeys, we advise people to plan ahead and allow extra time for their journeys and we thank people in advance for their patience.

“During the weeknight closures we’ll be carrying out work at the Carland Cross end of the scheme, and unlike the temporary Chiverton interchange, drivers won’t see too much change to their journeys.

“As part of the temporary arrangement at the Carland roundabout, people will be taken off to join a newly created section of the A30, and as part of the work, it’ll remove the need for a plant crossing which has impacted traffic flows at the eastern end of the scheme.

“We’ve communicated the forthcoming closures and changes to local communities and businesses and once that work is completed, drivers will be taken around the existing Carland Cross roundabout via a new, temporary alignment to continue their journeys along the A30.”

The new A30 carriageway is scheduled to be opened in winter 2023/2024, and in the meantime more information and further scheme updates are available at www.nationalhighways.co.uk/a30chiverton.

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 is being funded by central Government.
