This volume presents the results of archaeological investigations and mitigation undertaken along the route of the proposed A160/A180 Port of Immingham Road improvement scheme in 2015. Three major sites were identified along the route, with significant archaeological finds dating from the Bronze Age to the Anglo-Saxon periods. The bulk of the archaeological evidence related to late Iron Age and Roman-British settlements at three sites: Brocklesby Interchange, Rosper Road and Habrough Junction. The nature of these sites is examined and discussed, and their differing fortunes after the Roman Conquest are analysed to highlight issues of regional continuity and change within this dynamic period. Finally, a detailed discussion of the material culture provides an important corpus of new information for this region, in particular adding considerably to our current understanding of economic activities and ceramic supply in the north-eastern Lincolnshire area and the Humber region in general.
