Tens of millions of pounds are to be spent building a new road linking St Austell in Cornwall to the A30 in a bid to ease congestion and improve journey times for drivers.
The Government said the new 3.9-mile single carriageway road would include a shared cycle and pedestrian facility running alongside its full length.
The Department for Transport will provide a £78.5m in funding for the scheme, with Cornwall Council contributing £6.4m for an overall investment of £84.9m.
