Highways England has received the green light for more than £75m of upgrades to the A27 near Brighton.
The project will make up part of Highways England’s £15bn Road Investment Strategy and see four junctions upgraded between Lewes and Polegate.
The green light comes after 78 per cent of respondents to a Highways England consultation backed the need for improvements along the 14.5 km stretch of road.
The £75m scheme will also see the widening of the road between Polegate and Cophall, significant enhancements in improving walking and cycling facilities, and work to Wilmington junction.
The proposals are expected to improve the journeys of 26,000 travellers, with work set to start on site in spring 2020.
Highways England project manager Tom Beasley said: “People’s input has helped to shape our plans and we’ve made some key changes to our proposals to make sure they deliver the biggest benefit.
“In particular we’ve prioritised improvements at Polegate including the Gainsborough Lane junction, over the Selmeston bypass option and introduced a new enhanced option for upgrading the Wilmington junction – all as a result of people’s input.”
