Abstract:		 All work was undertaken to the standards described in the CIfA’s (2014) Standard and guidance for an archaeological watching brief. The MMSJV archaeologist followed CIfA’s (2014) Code of Conduct. The archaeological watching brief was undertaken by one MMSJV archaeologist who was present on site each day of excavation, while the test pits were being excavated and prior to their backfilling. The GI works commenced week beginning 14 January 2019, and then once a week until week beginning 28 January 2019. Additional test pits 7 and 8 were monitored later on 6 March 2019. Test Pits 1 and 2 were hand excavated by the principle contractor using a hydraulic breaker. Test Pits 3, 4, 5, 6, 7 and 8 were hand excavated by the principle contractor using insulated hand tools. The MMSJV archaeologist was able to enter the working area to carry out close inspection, record sections or create a photographic record. The results of the test pits indicate that there is varying potential for deposits of archaeological interest in the locations of the scheme that were monitored. Test Pit 1 and Test Pit 2 suggest that the repeated resurfacing of Roman Road has truncated potential remains of the former Roman road, Ermin Way. The former Roman road may yet remain preserved in other locations, however. The test pits located in the vicinity of the Air Balloon showed varying signs of archaeological potential. Three out of the four test pits monitored exhibited varying levels of made ground, two of which contained charcoal, indicative of human activity. The layer of limestone blocks between two silty fills observed in Test Pit 3 could represent a man-made deposit or structure, but would require further investigation. Test Pit 5 and Test Pit 6 in the land belonging to Star College also showed varying levels of archaeological potential, despite their close proximity. Test Pit 5 revealed c. 0.26m of made ground, whereas Test Pit 6 exhibited no made ground between the topsoil and the natural geology. No remains of significant value were observed in any of the test pits monitored, and no dateable evidence was recovered from the excavated material, which has resulted in a limited understanding of the archaeology. The test pits do, however, provide scope for further investigation, particularly by the Air Balloon. Any future archaeological work would need to be undertaken in accordance with an approved Written Scheme of Investigation (WSI).
