A three quarters of a million pound project unveiled by the Government this week aims to rid the M5 of its familiar traffic jams around Weston-super-Mare.
The town's MP John Penrose has welcomed this week's announcement of £750,000 to improve Junction 21 of the motorway .
It is the final chapter of a 10 year campaign to cut tailbacks and delays for local residents and businesses.
Mr Pensrose said: “This is the final piece of improvement to cut tailbacks and delays to keep Junction 21 moving.
“It's taken 10 years to get it done and finally Westonians have won. After this, Junction 21 will be at full capacity and we will need a whole new junction – Junction 21a – to cope with the next phase of growth."
The announcement came from Transport Secretary Chris Grayling as part of a package of Highways England road improvement schemes worth up to £20 million, which also promise to create thousands of jobs and homes in the South West.
The Government claims the planned improvements to the M4 and A30, as well as the M5, will unlock the development of more than 3,300 homes and create more than 6,000 jobs for people living in Swindon, Exeter and Weston-super-Mare.
Transport Secretary Chris Grayling said: “We're undertaking the biggest modernisation programme for a generation to bring our roads into the 21st century and give people the safe and reliable journeys they expect.
“But these improvements will do even more – allowing the construction of thousands of homes and the creation of thousands of jobs to give a huge boost to the area's economy."
Highways England is investing more than £11 million in these four schemes from its Growth and Housing Fund, with private sector developer contributions making up the rest.
The £100 million fund is in addition to the Government's £15 billion investment in roads between 2015 and 2020, and provides financial contributions towards the cost of road improvements that are needed for new developments which promise swift delivery of homes and jobs.
Jim O'Sullivan, Highways England chief executive, said: “We're committed to working with local partners to deliver specific schemes such as these which will make a real difference to communities and support regional economies.
“The improvements we are announcing today are necessary to accommodate the extra journeys the developments will create but without the Government investment they would not have been viable.
“We will continue to use our Growth and Housing Fund and work with a range of local stakeholders to unlock further development sites around the country."
