New research by the Road Safety Foundation has confirmed what many people in the 1066 Country area have been saying for years - the A21 is the most dangerous road in Britain.
The RSF rank roads in the UK-based on the number of crashes and traffic use.
The latest figures show there were nine fatalities on the East Sussex stretch of the A21 between October 2009 and 2014.
The Highways Agency, which manages the A21, says it is striving to make it safer but residents in villages such as Hurst Green and Robertsbridge, near Battle have been campaigning for years for lower speed limits and improved safety measures.
Outgoing Battle MP Greg Barker said more improvements were essential. He said: “Despite a number of improvements in recent years, the A21 still remains one of the most dangerous roads in Britain. I shall continue to press for further action.”
Members of the Sussex Safer Roads Partnership, which comprises councils, emergency services and safety campaigners, is also calling for action.
The A267 road, which runs from Frant past Heathfield was rated as a mid-level risk by the Road Safety Foundation.
A 2.5-mile section of the A21 between Tonbridge and Pembury in Kent is to be upgraded from single to dual carriageway, adding a lane in each direction, upgrading junctions and improving the road layout.
The works are part of a £69.7 million scheme to widen the stretch of road, and part of a record investment by the Government in road improvements of £24 billion by 2021.
Evidence given at a public enquiry last year showed that journey times will be improved along the section on the A21 by up to 65 percent in 2017 and the number of collisions reduced by 60 percent.
Construction is scheduled to start in spring 2015.
