Progress continues on the local road connections alongside the new A30 dual carriageway in Cornwall to bring the £330M scheme to its completion.
The newly dualled 14km stretch of the A30 between Chiverton and Carland Cross opened last June. Now National Highways, in collaboration with principal contractors Costain, is carrying out essential ancillary works, including the establishment of local road links, landscaping, and planting along the route.
Upcoming changes include the completion of the old A30 near Zelah, which is set to be transformed into the new B3288 between Chybucca and Boxheater, with the change scheduled for the weekend of 1 and 2 March. To enable the final phase of verge and telecommunications work in the lead-up to this transition, the A30 will undergo full overnight closures between Mitchell and Chiverton from 17 to 22 February, with closures taking place from 8pm to 6am. Diversion routes will be clearly indicated, guiding traffic via the A3076 and A3075.
Further modifications will see the old A30 between Carland Cross and Boxheater closed from 3 March for a period of four weeks, after which it will reopen as part of the new B3285. This closure is necessary to complete the construction of a multi-species tunnel and other finishing tasks required to connect different sections of the former A30.
In addition, work on developing the Carland Cross junction is ongoing, with temporary overnight traffic lights and lane closures on the main A30 continuing until March to facilitate verge finishing work.
The project team is in close communication with Cornwall Council and local stakeholders to keep communities informed as the project nears completion.
Financial backing for the scheme has come from a combination of sources: an £8M grant from the European Regional Development Fund, an additional £12M dedicated to construction, and further contributions from central government funding.
National Highways programme manager for the A30 Chiverton to Carland Cross scheme Andrew Alcorn said: “Opening the new dual carriageway has made a significant and positive difference to the journeys of both local communities and businesses, and to the wider travelling public, and we’re now moving towards completing the scheme as a whole.
“Traffic is now running smoothly on the new dual carriageway, we’re also progressing a significant amount of ancillary work, and while we progress towards completion, we thank people in advance for their co-operation and patience, and advise people to plan ahead and allow a little extra time for their journeys.”
