Source/Archive record SCH4295 - M6 Widening: Junctions 16-20: Report on Geophysical Survey

Following on from desk-top studies assessing the archaeological impact of the widening of the M6 motorway (ECH 3566), which identified 138 sites of archaeological/architectural and/or heritage interest within the study corridor, a programme of further evaluation was developed. Fieldwork strategies were prepared for 23 sites or areas, using a combination of five different techniques - fieldwalking, geophysical survey, earthwork survey, environmental sampling and trial trenching. The results of the geophysical surveys were reported in report SCH4295. Five sites were identified for geophysical survey, of these, two were the location of possible brick kilns, two possibly contained lengths of King Street Roman road and one was potentially the site of salt works. However, the majority of survey areas produced very few anomalies of archaeological interest and most of the data sets were dominated by ferrous responses, predominantly the result of buried pipes and other modern ferrous material. No brick kilns were positively identified.
