Highways England’s bid to dual the A30 Chiverton Cross and Carland Cross in Cornwall is being officially considered for a development consent order.
The £290M plan to construct a 14km dual carriageway has been accepted by the Planning Inspectorate for consideration.
Construction is planned to start in 2020, although work on the scheme first started in 2014.
Works will include a two-level roundabout and partial junction, slip roads and new bridges.
The scheme aims to reduce congestion on the road, which currently suffers from heavy traffic and pollution. It is the only stretch of single carriage way left on the road between Camborne and the M5 at Exeter.
