How much does A30 Chiverton to Carland Cross improvement cost?
The A30 Chiverton to Carland Cross improvement replaces a heavily constrained single-carriageway section in Cornwall with approximately 14 kilometres of high-quality dual carriageway. The scheme rebuilt the Chiverton and Carland Cross junctions, added the Chybucca grade-separated junction and delivered new bridges, underpasses, drainage and wildlife crossings. Work began in March 2020 and the new main carriageway opened on 24 June 2024. National Highways lists the project at GBP 330 million and reported that finishing and resurfacing works continued after opening.
