It means a proposal for a route through Northamptonshire is unlikely to be proceeded with. Northamptonshire CC is one of 25 authorities to fund research into three possible routes between East Anglia and central southern England.
One of the routes considered was a northern link through Corby, Kettering and Wellingborough. Consultants decided it had less potential than a central link through Cambridge, which would also link the ports of Felixstowe and Harwich.
A second route through Stansted has also been rejected.
