Summary Five evaluation trenches were targeted upon several geophysical anomalies identified at the site of a proposed road junction development. The ditches of two enclosures were exposed in the northern half of the site. One of these remains undated, while the other is tentatively dated to the late Iron Age/early Roman period. Two sections of a ring ditch were exposed in the southern half of the site and appear to relate to a ploughed-out round barrow. In the centre of the site, the course of the scheduled West Wansdyke earthwork was exposed but not further excavated. Rubble representing the core of the bank was consistent with evidence found during other local excavations, and possibly suggests that the earthwork here had a stone revetment. All the features excavated at the site appear to have suffered from later truncation. ©Oxford Archaeology Ltd vii 29 August 2017 A39/B3116 Road Improvements (Two Headed Man Junction) 1 Acknowledgements Oxford Archaeology would like to thank Bath and North East Somerset Council
