Three ditches were recorded in evaluation work along a proposed road scheme north of Ridham avenue. Just south of the proposed junction 4, the ditches produced Late Iron Age and/or Romano-British ceramic material. Two of the ditches appeared to be part of a still visible linear embanked earthwork, interpreted as probably part of an abandoned hollow way. The report states that the waterlogged nature of the area indicates good potential for the survival of high quality paleo-environmental evidence. The features were recorded within a 50m trench, which the grid refs below mark the approximate extent of. In and around junction 4 a complex pattern of intercutting features dated to the Mid-Late Bronze Age were recorded (TQ 96 NW 97), while to the north further prehistoric features were recorded (TQ 96 NW 96).
