Constantine's Bridge (Latin: Pons per Danuvium Ductus,[4] Bulgarian: Константинов мост, Konstantinov most; Romanian: Podul lui Constantin cel Mare) was a Roman bridge over the Danube used to reconquer Dacia. It was completed in 328 AD and remained in use for four decades.[5]

It was officially opened on 5 July 328 AD in the presence of emperor Constantine the Great.[2] With an overall length of 2,434 metres (7,986 ft), 1,137 metres (3,730 ft) of which spanned the Danube's riverbed,[6] Constantine's Bridge is considered the longest ancient river bridge and one of the longest of all time.[7]
