"Anything that improves that section of road has to be a benefit to west Norfolk. It's a real positive step which we're really supportive of." James Palmer, mayor of Peterborough and Cambridgeshire, said: “We’ve always had a good case for dualling, and I have been determined to get this done." The EDP-backed Just Dual It campaign, launched in 2018, called for all 115 miles of road between Peterborough and Lowestoft to be dualled at a then-estimated cost of £1.5bn. So far six stretches have been earmarked for improvement. A planning application is being drawn up to dual the road between Wansford and Sutton, west of Peterborough.
