History
The Roman bridge in El Kantara is a Roman stone bridge over Wadi El Hai in El Kantara, Algeria, built in AD 335 during the Roman period. It connected the fertile northern Tell, Algeria’s northern belt, with the Sahara and formed part of a route used by military movements, communications, and commercial caravans.
The bridge is associated with the reign of Constantine, a Roman emperor whose rule began in the early fourth century AD. During French colonial rule, it underwent extensive restoration in 1862 under the direction of Napoleon III, emperor of the French Second Empire from 1852 to 1870. The Roman structure and arch were retained, while the upper surface was adapted for modern vehicles. The bridge is protected as a national heritage site of Algeria.

Stone Arch and Gorge Crossing
The bridge occupies the narrowest part of the El Kantara gorge, where it crosses Wadi El Hai between the Atlas mountain region and the desert south. Its single arch spans approximately 10 metres and forms a physical passage between the northern Tell zone and the Sahara.
Local limestone forms the bridge, with the arch constructed from carefully cut stone. Its survival is attributed to the balanced compressive forces within the masonry rather than to modern cement or adhesive. The limestone was durable enough to withstand the severe desert climate, while the upper surface was later adapted for vehicle use during the 1862 restoration.
