The 8 miles currently is around Hailsham and Eastbourne. There's no dual carriageway on the A21 in E Sussex. I've given up writing to the MP about anything we're just the poor relation in the South East. Kent and West Sussex are like a different country in comparison.Should've extended all the way in.
They took long enough to build the bypass between Bexhill and Hastings, which has improved things in that respect.
