NATIONAL Highways is reminding drivers to plan ahead and allow extra time for their journeys ahead of this weekend’s closure of the A30 near Truro.

As part of National Highways’ A30 Chiverton to Carland Cross upgrade, traffic will be realigned on a new gyratory as part of work to remove the Chiverton Cross roundabout, Cornwall’s worst accident hot-spot.

The work, which will take place under a weekend closure between Scorrier and Boxheater, will see the A30 realigned to the east and west of the current roundabout, with a contraflow in place, which will maintain access to the A390, A3075 and B3277 while further work continues during the year.

The weekend closure will also see a two-mile section of the A390 closed from the Chiverton roundabout to Langarth Park, from 7pm on Friday, to allow for works to construct the new westbound slip road configuration at Three Burrows.

Access for residents and businesses in this area will be maintained during the weekend, and information has been distributed locally where restrictions are in place.

During the closure, from 8pm on Friday, 16 June to 6am on Monday, 19 June, eastbound traffic will be diverted via the A3075 to Goonhavern and the B3285 to re-join the A30 at Boxheater, with the westbound diversion operating in reverse.

For HGVs and Truro access, the diversion will be via the A39, A393 and A3047, while access will be maintained across the A30, via the B3284 at Chybucca for emergency services’ vehicles, and diversion routes have been communicated to bus companies.

Neil Winter, National Highways’ Senior Project Manager for the scheme, said: “The reconfiguration of the A30 at Chiverton represents a real milestone for the project, and with the Chiverton roundabout effectively disappearing, drivers using the A30 will see this taking shape after the weekend and will see a real difference once the scheme’s completed.

“We appreciate the closure will have an effect on people’s journeys, and we understand roadworks can be frustrating and ahead of the weekend closure, we advise people to plan ahead, add extra time for their journeys or avoid the area if possible.

“In the meantime, we’ve communicated the diversion routes to local communities and businesses, more information is available on our website, and we thank drivers in advance for their patience while this significant work takes place.”

The new 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.
