The A259 and A2070 are part of the national route along the south coast between the south Hampshire conurbation and the Channel Tunnel.
The road alignment at Winchelsea is particularly poor with a steep hill and hairpin bend where the road skirts the town, which affects traffic flow and forces large vehicles to cross to the wrong side of the road.
Through Rye, where the road is subject to a speed limit of 30 mph, the road follows a tortuous route immediately south of the picturesque town centre and parked vehicles often obstruct the flow of traffic.
