New openings ahead as Cornwall’s A30 upgrade closes in on completion
Work is progressing to open local roads alongside the new A30 dual carriageway
Last updated 11th Feb 2025
National Highways says work is progressing to open local roads alongside the new A30 dual carriageway in Cornwall.
Since opening the road to traffic last June, National Highways and principal contractors Costain have been continuing ancillary work, such as local road connections, landscaping, hedging and planting along the new 8.7-mile route.
As part of that programme, work on the old A30 near Zelah is being completed before opening as the new B3288 between Chybucca and Boxheater over the weekend of 1/2 March.
To enable the final phase of verge and telecommunications work, full overnight closures of the A30 will also be in place between Mitchell and Chiverton from Monday, 17 February to Saturday, 22 February.
We are told the closures will be in place from 8pm to 6am, with clearly signed diversion routes via the A3076 and A3075.
The old, realigned A30 between Carland Cross and Boxheater will be closed from Monday, 3 March for four weeks, before reopening as a new section of the B3285.
National Highways says the closure is needed to complete work on a multi-species tunnel, as well as other finishing work in order to join up sections of the old A30. During the closure traffic can access the A30 via the B3285, A3075 and the A3076.
Andrew Alcorn, National Highways’ Programme Manager for the A30 Chiverton to Carland Cross scheme, 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.”
Work to complete the Carland Cross junction is also continuing over the next few weeks under temporary overnight traffic lights and overnight closures, while westbound lane closures of the main A30 will continue until March for finishing work on the verges.
The cost of developing the scheme has been funded by an £8 million contribution from the European Regional Development Fund, with an additional £12 million for the construction phase.
The remainder of the cost of developing and delivering the scheme has been funded by central Government.
