The evaluation fieldwork comprised the excavation of 10 trenches measuring 40m in length and 1.8m in width. The trenches were located to test geophysical anomalies and to provide a representative sample of the remainder of the site. In June 2022, Cotswold Archaeology carried out an archaeological evaluation of land at Kings Weston Lane and to the west of Access 18, M5 (Plot A), Avonmouth, Bristol. A total of 10 trenches were excavated. The evaluation recorded a series of geological deposits, described as estuarine sediments and alluvial deposits, with a potential soil horizon predating the Upper Wentlooge Formation that began to form around 1500-500 cal BC also being identified. A single sherd of pottery of broad Roman date was recovered from the upper alluvial deposit identified in a trench excavated in the central part of the site and is probably residual by virtue of its abraded nature. A single undated ditch, corelated closely to a field boundary depicted on the in 1840s Tithe map was identified in a trench excavated in the central part of the site.
