'A hidden but powerful influence on the Oxford crossing is the presence
of two Roman roads, cutting obliquely across the Thames-Cherwell confluence
and converging on Frilford to the south-west. The
more northerly served an extensive Roman settlement in the North Oxford
area; the other left the Dorchester-Alchester road near Headington Quarry,
crossed the Thames channels near modern Donnington Bridge and at Redbridge,
and continued over Boars Hill. The Redbridge section partly survives as
an ancient causeway; its small, spaced-out flood-arches resemble those
of the Norman Grandpont, but they could just possibly be Roman. Somewhere
near this point, the late Anglo-Saxon bounds of Kennington and Hinksey
mention a 'stone ford' (stanford).'
