Plans to dual Cornwall A30 bottleneck get go ahead

Plans to dual Cornwall A30 bottleneck get go ahead

Published by Sarah Yeoman at 1:58pm 7th February 2020. (Updated at 4:38pm 7th February 2020)

Plans to dual the A30 between Chiverton and Carland Cross have been given the go ahead.

The government has granted development consent for one of the last big bottlenecks in Cornwall.

It comes after a big consultation was held and it is estimated that the scheme will cost around £290 million.

A new 12.5km off-line section of road will be constructed and a new grade separated junctions at Chiverton and Carland Cross, and Chybucca. 

The majority of the existing A30 will be retained as a local route.

The 8.7-mile road scheme includes:

  • a 70mph high-quality dual carriageway 
  • a two-level junction at Chiverton Cross and a new roundabout to ensure the free flow of traffic on the A30
  • a new partial junction at Chybucca built on two levels with west-facing slip roads to provide access onto the dual carriageway from local routes 
  • new bridges at Tolgroggan Farm, Pennycomequick Lane and over the Allet to Tresawsen road to provide local access
  • a two-level junction at Carland Cross with a new roundabout north of the dual carriageway and re-using the existing roundabout to the south
  • keeping the existing A30 as a local route with new sections where necessary to provide continuity and connectivity for local communities

What the route could look like

“We’re delighted to receive the Secretary of State’s decision, which represents a major step in developing a scheme to help unlock congestion, promote economic growth and bring out better connectivity for local communities along the A30.

“Improving the A30 between Chiverton and Carland Cross is incredibly important for Cornwall’s future.

“It's the only remaining stretch of single carriageway on the A30 between Camborne and the M5 at Exeter; journeys on this part of the road are regularly delayed, congestion often brings traffic to a standstill, and as a result the Cornish economy is being held back.”

Highways England Senior Project Manager, Josh Hodder

He added: "“The existing A30 will remain open while the scheme is built alongside.

"We are currently finalising our construction partner, all phases of the work and associated traffic management will be explained to the local community before we start, and ongoing communication will keep people updated throughout.”

Following the granting of planning consent, main construction works are scheduled to start later this year, with the route expected to be open to traffic in 2023. 

During construction, the work will take place away from the existing A30 route to ensure continuity for traffic.

The cost of developing the scheme is being partly 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 is being funded by central Government.
