  In 1993, remains of a Bronze Age bridge were found on the south River Thames foreshore, upstream from Vauxhall Bridge. Two of the timbers were radiocarbon dated to 1750–1285 BC. In 2010, foundations of a large timber structure, dated to 4800–4500 BC, were found on the Thames's south foreshore downstream from Vauxhall Bridge. Both structures are on the south bank of the Thames, where the now-underground River Effra flows into the Thames.
