Existing Issues

Locally there are significant concerns about HGV vehicles and volumes of traffic travelling through the villages to the north of St Austell. This creates:

• congestion
• noise
• poor air quality
• an unfriendly pedestrian environment
• concerns about road safety

St Austell is isolated from Cornwall’s main strategic A30 road network. The current links to the A30, via the A391 through the villages of Bugle and Stenalees or the B3274 through Roche are inadequate. This makes it hard for businesses to be competitive and deters business development, employment and growth within St Austell and the China Clay area.

Scheme History

Study in early 1990’s identified alignment to east of Bugle connecting to Innis Downs 2003-05 study looked again at options and confirmed preferred alignment

comprising

• 1.6km section of new road
• a new roundabout, and
• two new bridges

Completed by the Council in 2015 at a cost

• f approximately £13 million.

Catalyst for Regeneration

Mid Cornwall Economic Corridor

A30 to St Austell Link Road Objectives

 Create a better link between two of Cornwall’s largest towns – St Austell and Newquay, the airport and Aerohub Enterprise Zone  Make it easier to get to Cornwall’s new, large employment sites. Therefore supporting the expanding employment sites: Victoria Business Park; Indian Queens Industrial Estate; Aerohub Enterprise Zone; and the Carluddon Technical Park.  Improve competiveness of St Austell as a location to do business via new employment space or interest in land that can be developed into employment space; creating 600 and 500 jobs respectively.  Address congestion and support housing growth, including the delivery West Carglaze eco-community; creating 1,500 new homes and 500 jobs. (by providing 15-18,000sqm of employment spaces)  Support the regeneration of Roche and Bugle, by addressing traffic issues and provide better opportunities for businesses.

Link to St Columb Major/ Newquay North

Complementary measures to reduce through traffic in villages

• 1. HGV ban through the villages
• 2. Traffic calming / priority

buildouts to reduce attractiveness

• f route to through traffic
• 3. Widen footways and on street

parking to significantly reduce capacity for vehicles

• 4. Local highway improvements –

widening and junction improvements

• 5. Average speed cameras on

through village routes

• 6. Prevention of through traffic in

both villages

Recommendations

• 1. That the preferred route for the A30 to St Austell Link Road as

detailed in the report be approved.

• 2. That the Service Director for Transport and Infrastructure be

granted delegated authority to submit the Outline Business Case to Central Government Department of Transport for the A30 to St Austell Link Road on the basis of the preferred route recommendation.

• 3. That the preferred route identified in this report is formally

safeguarded against future development. The extent of the safeguarding includes the current route alignment with a 100m buffer zone on both sides as shown on the plan in Appendix 5.

• 4. That the safeguarding of the former preferred route to the east of

Bugle from the 2003/05 study as shown in Appendix 6 is deleted

Parkandillick Link

www.cornwall.gov.uk

Parkandillick Link

• an estimated cost in the order of £8-10 million
• complexities involving a rail and road bridge to

achieve the link

• unresolved operational issues relating to connecting

private roads

• limited strategic benefits
• Parkandillick Link would not meet DfT funding

criteria.

• The inclusion of this link would potentially

undermine the Outline Business Case bid for the A30 to St Austell Link Road.
