Question to the Department for Transport:

To ask Her Majesty's Government what proportion of the A30 trunk road between Exeter and Penzance is not yet dual carriageway; and what plans they have to convert those sections to dual carriageway.

Approximately 16 per cent (17 out of 109 miles) of the A30 trunk road between Exeter and Penzance is not yet dual carriageway. The remaining single carriageway sections are between Carland Cross and Chiverton Cross, and between Camborne and Penzance.

The Government has committed to dualling the A30 between Carland Cross and Chiverton Cross (9 miles of the above 17 miles of single carriageway), with construction work due to start in 2019-20.

Proposals to dual the A30 between Camborne and Penzance will be considered as part of decisions on the second Road Investment Strategy covering the period 2020-2025.
