The Combe Haven Valley houses rare plants and wildlife but in January much of the greenery is set to be replaced with concrete as a £100 million pound road building programme begins.
There've been protests about the scheme ever since the route was unveiled five years ago but now East Sussex County Council has been told it can go ahead with the compulsory purchase of the land.
This weekend opponents of the scheme have been holding a series of events to discuss what they can do to stop the road.
East Sussex County Council says the project is vital to improve links between Bexhill and Hastings; will help create four and a half thousand jobs, many on a new business park, together with up to two thousand new homes.
But opponents say destroying an area of natural tranquility and beauty is too high a price to pay
Work is due to begin in January but one protest group is hoping to win a judicial review which would put a temporary halt to the plan; but if they're not successful campaigners say they may have no option other than to take direct action.
