Between April and August 2007 an area of 2.9 hectares within the corridor of the proposed link road from the M11 to Addenbrooke's Hospital was excavated (Site 3 Areas A and B). Archaeological features were largely confined to the north-western part of the site.Pre-Middle Bronze Age activity was minor, confined to a Neolithic and single cluster of Early Bronze Age pits. Middle Bronze Age occupation was characterised by a NW-SE aligned rectilinear field system from which came the remains of a Deveril-Rimbury urn and the establishment and re-cutting of a large enclosure ditch.Within the same area were a number of Middle Bronze Age burnt stone spreads including a pair of cooking pits.Late Iron Age activity was confined to a poorly developed field system and the edge of a north-south ditched trackway which seems to follow the edge of the terrace northwards along the side of the valley. Small-scale quarrying begins on the eastern side of the site towards the end of the Late Iron Age, as does the first establishment of a cultivation enclosure during the immediately pre-Conquest Period. By c.50-60 AD the cultivation of asparagus is taking place within the far north-west corner of the site, perhaps indicating the presence of an as yet unknown villa/farmstead.Quarrying continues through into this Conquest-Early Roman period whilst the ditched enclosures of much larger paddocks can be traced eastwards across the valley floor.By 80-100AD the Site 3 area seems to have been largely abandoned. Gravel and marl quarrying continued in the Post-medieval period along with the cutting of field ditches and land drains in the 19th century.
