Motorists will get a sneak preview of the new Bexhill to Hastings Link Road - months ahead of its official opening.
A 0.6 mile section of the new route, due for completion in May next year, will be opened to traffic after the morning rush hour on Monday, September 29.
The opening of the road between the junction of the A259 Belle Hill and A269 London Road and Ninfield Road Bridge is timed to coincide with the start of demolition work on the bridge.
Bob Pape, East Sussex County Council’s Link Road project manager, said: “This is a very significant milestone in the development of the scheme and we are delighted that residents and other motorists will be able to benefit immediately from the work before the new road is fully open.
“I would like to thank everyone who has worked so hard on the project to make this happen.”
Once the section of road opens, work will begin on demolishing Ninfield Road Bridge, which is too low and narrow to allow traffic on the new road to pass underneath it, and replacing it with a new crossing.
The replacement will be a single span, simply supported bridge, made from a steel and concrete composite construction in keeping with the existing brickwork retaining walls.
The 3.5 mile single-carriageway Link Road will connect the outskirts of Bexhill and Hastings. Starting at the A259 in Bexhill it runs along the disused Bexhill to Crowhurst railway line, crosses Crowhurst Road and the Hastings to London railway line before joining Queensway at Hastings.
