Twelve arches; the middle ones are segmental with a span btw. 19.50 and 24.50 m; the remaining arches are semi-circular with a span btw. 3 and 9 m. The six piers of the main arches are ca. 7.50 m wide with rounded breakwaters facing upstream and pointed ones downstream. They rise to the full height of the structure and appear to be substantial buttresses.
Adjacent Structures: The western bridge entrance was once accentuated by a triumphal arch. It has completely vanished except for its footings. As a counterpart a still extant apsed structure stands at the eastern end.
Material and Technique
Mortared rubble core is faced with medium-sized ashlars of local limestone in horizontal courses. The segmental arches are composed of voussoirs in a double ring, whereas the small arches have a single ring.
Decoration
Relief crosses on two keystones are still preserved.
Donors
Emperor Justinian I (r. 527-565)
Primary Sources
An epigram by Agathias (6th c.) once inscribed on the bridge, survives in De Thematibus by Constantine Porphyrogenitus.
