THE 5.5-kilometre new road starts on the Kingsteignton bypass at Penn Inn with a flyover over the roundabout.
Heading south there is a short section of dual carriageway, which would be provided by widening the existing road, to the north of Kingskerswell at Aller where a major junction would provide access to Kingskerswell and the Old Newton Road to Decoy.
From here, near the Barn Owl pub, the 50mph dual carriageway swings west to bypass the village and connects to the dual carriageway at Hamelin Way/Torbay Ring Road at a traffic signal controlled junction.
Here the 'significant junction' sees two lanes going to Torquay and two lanes going in the Paignton direction each stopping at a set of lights.
The Kerswell Gardens roundabout is replaced by a set of traffic lights and a change in priorities of the traffic flows. According to Devon County highways chiefs these junctions are specially designed to supply the capacity that is needed.
Following a public inquiry and in response to public consultation and on counsel's advice, elements have been reinstated including a local link road at Aller Park, a local side road and rail bridge at Aller, a north bound off-slip and a southbound on-slip road at Aller, dualling at Hamelin Way, including the Kerswell Gardens junction.
The case for the scheme states the A380 is one of the busiest single carriageway roads in Britain. It carries around 35,000 vehicle trips a day, running at capacity.
While awaiting the road, Torbay's economy has slid further down the rankings of prosperous authorities from 353rd in 1997 to 379th.
The bid to Government says the new road will open up the potential for investment and will lead to the creation of an additional 7,690 jobs and an extra 750 in the tourism sector, with 4,190 of those jobs in the wider Devon area.
The councils cite independent research which found £9 would be generated for the local economy for every £1 spent on the scheme.
It is also predicted that the new road will contribute to the expansion and retention of local businesses, retail and tourism activity across the area.
The bid says that both Torbay and Teignbridge are planning significant housing and employment development and the new road specifically opens up potential growth areas at each end of the scheme, around Penn Inn and Kerswell Gardens.
The report says that further development and extension of the urban area around the northern Torquay and southern Kingskerswell area will be encouraged by the scheme.
There is currently residential development taking place around the southern end of the scheme and this is likely to expand in the new local plan, says the report.
Work has already started on delivering a new station in the area, and access to Edginswell business park will be improved.
There is considerable employment land in Newton Abbot next to the A380, and the new road would enable these employment sites to expand to the east of Newton Abbot. There are also options for residential developments to the east of Newton Abbot with connections to Penn Inn junction and the new road.
It will also reduce air pollution in Kingskerswell by reducing the traffic on the Newton Road by 90 per cent.
The number of accidents will also be reduced from the 200 plus on the stretch between Penn Inn and Kerswell Gardens between 2004 and 2010.
