The recent completion of the A30 dual carriageway marks a significant infrastructure milestone in Cornwall, enhancing connectivity and local economy.
- The project, opened on 24 June, involved extensive dualling, upgrade, and widening works along the A30.
- Key structures include three new bridges and 10 new underpasses, addressing critical transport needs.
- Environmental considerations were prioritised with 150,000 trees planted and multi-species crossings added.
- This ambitious project overcame numerous challenges, including adverse weather and the impact of the Covid-19 pandemic.
The A30 dual carriageway project, completed by Costain, marks an essential infrastructure advancement in Cornwall. Officially opened to traffic on 24 June, this National Highways scheme addressed long-standing transport issues through comprehensive dualling, improvements, and widening efforts, all of which were deemed critical for the region.
The development, stretching between Chiverton and Carland Cross, was significant not just for its scale but also for its structural achievements. Among the key accomplishments were the dismantling and replacement of the 32-year-old Tolgroggan bridge and the creation of a new traffic-free bridge at Chiverton. In addition, the notorious ‘Chivvy’ roundabout was removed to improve traffic flow and safety.
Recognising its importance, the project was also designed to bolster the local economy and environment. Among its environmental initiatives were the planting of 150,000 trees, the creation of 4.5 hectares of new woodland, and the installation of 33 crossing points promoting wildlife safety along the route.
Costain, along with National Highways and various supply chain partners, navigated numerous challenges, from the Covid-19 pandemic to severe weather events. At its peak, the project employed over 650 workers, demonstrating a collaborative effort in realising this vision despite the difficulties encountered.
Looking ahead, finishing touches such as landscaping, planting, and structural refinements are set to complete the scheme in the coming months. These efforts reflect a commitment to ecological enhancements and civic improvements.
The success of this project not only alleviates congestion for local communities and visitors, especially during peak times like the school summer holidays, but also represents a dynamic stride towards modernising infrastructure in the south-west region.
The A30 dual carriageway project successfully enhances Cornwall’s transport infrastructure while supporting environmental and economic goals.
