An archaeological evaluation was undertaken prior to residential development on land at 82 Main Road, Washingborough. The site lay on the postulated line of the Car Dyke Roman waterway and at the edge of the medieval town. Two trenches were excavated; one measuring 20m x 1.6m and the other 20m by 3m. These were placed toward the north-east corner of the site, overlapping the postulated line of the Car Dyke channel and its southern flanking bank. {1} {2}
