An archaeological evaluation was undertaken by the Cambridge Archaeological Unit (CAU) between April and November 2009, along the corridor for a proposed re-routing ('off-line') and widening ('on-line') of the A14 road between Girton (NGR 541700 261270) and Ellington (NGR 518800 271900) (referred to as the Scheme). In total 13 areas were trial trenched. As a result of these evaluations 20 individual sites have been identified along the Scheme which spanned from the Late Neolithic through to the Anglo-Saxon period. Three Neolithic sites were identified, two Late Prehistoric sites were recorded with little artefactual material to enable a more precise date. Seven Middle Iron Age sites were identified spread throughout the Scheme. Late Iron Age activity was recorded at two of the sites. Four Romano-British sites were recorded and Anglo-Saxon settlement was identified at two sites.
