In the late autumn of 1968 gravel-quarrying at Aldwincle, Northants., brought to light a timber bridge of the Roman period. The working face of the gravel-pit fortunately coincided with one side of the bridge, and thereby exposed the structure in section (PL. IX A). Excavation of the bridge was carried out by D. A. Jackson during the winter of 1968/9 under the sponsorship of the Ministry of Public Building and Works.
