The £117 million benefits of dualling a stretch of the A30 in Cornwall will move a step closer to being unlocked next week when a planning application for the scheme is submitted.
The £60 million project would see a 2.8-mile single lane stretch of the A30 from Temple to Higher Carblake turned into dual carriageway in a bid to reduce tailbacks which can reach up to six miles in each direction.
It was one of the main items on the South West's infrastructure shopping list when the Chancellor announced £30 million in government funding to get it moving.
Tourism and business leaders have long called for the work to go ahead and Cornwall Council has been trying to progress it for the last 25 years.
Adrian Penter, Cornwall chairman of the Federation of Small Businesses, said: "It's very much welcomed, particularly when other schemes have not had the green light to go ahead."
Members of Cornwall Council's cabinet will tomorrow be asked to approve measures for the council to negotiate to buy land around the road in order for the development to go ahead. They are also being asked to approve powers of compulsory purchase, if needed.
A total of £20 million of the remaining funding is likely to come from the next round of European funding, with a grant application due next summer. The final £10 million is expected to come from Cornwall Council.
A planning application is due to be submitted to the Planning Inspectorate on August 7.
