Major Cornwall dual carriageway scheme to begin
Works to build a new dual carriageway for the A30 are expected to start later this year.
Highways England will soon be upgrading one of Cornwall’s worst bottlenecks – the A30 between Chiverton Cross and Carland Cross.
The plans will see an entirely new road built between the two busy roundabouts, with the old road to the north being retained and downgraded to a local route.
This includes an 8.7-mile, 70mph dual carriageway. Chiverton Cross and Carland Cross would both be replaced with two-level motorway style roundabouts.
There would be a two-level partial junction at Chybucca – the junction with the roads to Perranporth and the road through Shortlanesend to Truro – with west-facing slip roads and new bridges across the new road and the old road.
The existing A30 will be kept for local traffic.
Highways England awarded a contract for the work to construction and engineering company Costain on March 31.
The same month, it also began preliminary works, which include ecological surveys, ground investigation work, topographical surveys and utility diversion work.
Those works are still ongoing, although methods of work have been updated to follow Government advice during the lockdown and the coronavirus pandemic.
Highways England has now confirmed that the main work is set to start in the autumn.
Josh Hodder, Highways England’s senior project manager for the A30 Chiverton to Carland Cross scheme, said: “We are currently working with Costain, the contractor who will design and build the scheme, and they are currently working on the detailed design.
“We will provide more information about how the construction process will be managed in due course, including how we plan to minimise disruption to drivers and local residents.
“All construction phases and associated traffic management will be explained to the local community before we start, and ongoing communication will keep people updated throughout.”
The new road is expected to be open for traffic in 2023 or 2024.
