The final phase of Torbay's Council's £16.5 million Western Corridor project starts today - along with separate work in Totnes.
Officials say the £700,000 scheme at the Windy Corner junction between Paignton and Brixham will improve traffic flow and reduce queueing at peak times.
The changes will provide an additional approach lane for traffic heading towards Paignton, created by constructing a new lane towards Brixham, which uses a short section of Bascombe Road.
The scheme, and works currently taking place on Brixham Road by Sainsbury’s, will be completed this Summer.
Mayor Gordon Oliver said: "This is a major road improvement which is beneficial to business for the whole of Torbay specifically needed to assist the growth of business in Brixham, including the fishing industry, and the surrounding area.
"This scheme is very welcome."
Councillor Robert Excell, Executive Lead for Community Services said: "The Windy Corner junction has long been a cause of frustration for motorists, especially during busy periods, and traffic queues have often been significant.
"This junction is a vital link between Paignton and Brixham and the rest of the Bay and when completed this will make a big difference to travelling times.
"The Local Plan, Local Transport Plan and Brixham Neighbourhood Plan all recognise the importance of finding a solution at this junction and we have worked with the community to provide a solution that appreciates the unique natural environment and protects the common land.
"Inevitably the implementation of a scheme in such a congested location will cause some disruption to motorists at times, but we will make every effort to keep delays to a minimum and look forward to the significant improvements in traffic flow once the works are complete.
"The scheme is part of the Torbay Western Corridor Scheme to provide capacity improvements to the A3022 West of Paignton, and open up the area for businesses and residents.
"We have worked closely with the Heart of the South West Local Enterprise Partnership to submit the successful bid, and the funding recognises the strategic importance of the scheme.
"The Western Corridor Project, which has been made up of improvements to five sections of the Torbay Ring Road between Churscombe Cross (Marldon) and Windy Corner, is substantially funded by £8.25 million from the Heart of the South West Local Enterprise Partnership’s Growth Deal.
"This is a considerable investment into the infrastructure of this area of Torbay, which is already seeing large residential and commercial growth."

There's also going to be five nights of overnight closures on the A385 in Totnes from tonight.
The road, which runs past Totnes railway station, will be closed from 7pm to 7am.
It means there'll be a diversion to get to and from the station between those times.
A spokesman for Devon County Council said: "Overnight closures will be needed to carry out essential resurfacing on Station Road and Ashburton Road in Totnes.
"The A385 in Totnes will be closed for five nights starting from Monday 11 March. The road, which runs past Totnes railway station, will be closed from 7pm each evening, re-opening no later than 7am the following morning.
"People who live or work within the area of the closure will be allowed access to homes and businesses during the night-time closures, although they may be asked to wait a short time until it is safe to do so. Access will be maintained at all times for emergency vehicles.
"The closure will impact access to the railway station overnight, and vehicles will only be able to enter the station from the Morrisons side. Anyone arriving in Totnes on a train after 7pm will need to follow the contractor’s instructions to leave the station via the road closure. Pedestrian access to and from the train station will be maintained from both directions at all times.
"The official signed diversion route will be in place via the A385, A384, A38, A383, A382, A381 and A385. Temporary traffic lights will be in place on the A385 for traffic travelling to and from Kingsbridge via the A381 Western by-pass.
"During the closure, work will also be carried out to clean road drains and rebuild a manhole chamber under the road.
"The scheme will be carried out by contractor South West Highways."
