Carrville Interchange, Durham
NZ 3069 4454; Emma Allen; evaluation; April-May 2005; CAR 05.
The first stage of fieldwork at Carrville Interchange comprised fieldwalking across the western portion of the site, which had been recently ploughed. The majority of the artefactual material recorded was of post-medieval date. Earlier material comprised a single struck flint and three sherds of medieval pottery.
Fieldwalking was followed by the investigation of seven evaluation trenches. Natural boulder clay was exposed in all of the trenches. The earliest archaeological features recorded comprised plough furrows, present in all trenches investigated, with the exception of Trench 5. These were regularly and narrowly spaced furrows, broadly indicative of post-medieval agricultural practice. A sandstone structure of uncertain function was recorded in Trench 1, truncated by a drainage ditch. Modern activity was represented by service trenches exposed in Trenches 4 and 5, along with an associated dump deposit in Trench 4. Ploughsoil was the uppermost deposit recorded in all of the trenches investigated.
