Protesters angry at plans to build a £100 million pound link road between Hastings and Bexhill are holding a rally against the plans.
Local traders say the new road is vital to boost the economy.
But campaigners say that the route will endanger a site of special scientific interest and that there is no economic need for the new infrastructure.
Work on the scheme is due to start next January but opponents of the plans are hoping to win a judicial review.
"We are determined to stop this road and if necessary some of us are prepared to take direct action".
