National Highways is advising drivers to plan their journeys ahead of work resuming next week under closures of the A30 in Cornwall.

As part of the A30 road upgrade between Chiverton to Carland Cross, work will take place under overnight closures, from 8pm to 6am from Monday, January 8 to Wednesday, January 10, followed by a full weekend closure from 8pm on Friday, January 12 to 6am on Monday, January 15.

During this time, westbound traffic will be diverted from Boxheater on the A30 via the B3285 and the A3075 to rejoin the A30 at Scorrier, with the eastbound diversion route in reverse.

Due to a low bridge (4.7 metres) at Scorrier, HGVs will be diverted via the A393 and A39 to rejoin the A30 at Carland. 

The new year programme of work follows pre-Christmas closures, which saw the partial opening of the temporary surfaced Chiverton flyover, and the opening of the north-south B3284 link across the Chybucca junction.

Work next week will involve further surfacing across the Chiverton flyover, significant drainage and central reservation work at the western end of the scheme, and other construction work close to the live carriageway.

Neil Winter, National Highways’ senior project manager for the A30 scheme, said: “The partial flyover opening was a real milestone for the project, and both the flyover and the B3284 link opening at Chybucca have helped to improve traffic flows for people travelling through and across the scheme.

“After next week’s work, motorists should experience smoother journeys but won’t see any difference to their travel.

“We need to have the closures in place to carry out the work, and we advise people to plan ahead and allow extra time for their journeys.”
