Ancient Roman bridges represent one of the greatest wonders of the Ancient World. They were an exceptional feat of Roman construction. The Romans were undoubtedly the first people to build large and lasting bridges. During the Roman period, bridge building techniques were revolutionised with the introduction of arches which enabled the Romans to erect structures of great beauty and solidity. With such powerful knowledge, Roman road builders spread across Europe, Asia and Africa, building over 900 bridges during the Roman Republic and Empire.
A list of Roman bridges compiled by the engineer Colin O’Connor features 330 Roman stone bridges for traffic, 34 Roman timber bridges and 54 Roman aqueduct bridges, a substantial part still standing and even used to carry vehicles. A more complete survey by the Italian scholar Vittorio Galliazzo found 931 Roman bridges, mostly made of stone, in as many as 26 different countries, from Portugal on the west, to Syria on the east (see
List of Roman Bridges).
Testament of the building techniques of Ancient Rome can be witnessed even today with hundreds bridges still standing. The following list includes all the surviving remains of Roman bridges I have seen and photographed. They are listed by country of origin.
Roman bridge on the Via Egnatia (41°02’53.3″N 19°45’53.5″E)

Roman bridge of Salona ( 43°32’18.3″N 16°29’01.4″E)
In the east suburb of Salona, outside the walls enclosing the old city, the Urbs vetus, the westernmost backwater of the Jadro (the ancient Salon) was flowing. In the 1st century BC it was spanned by a five-arch bridge supported by massive pillars. It was constructed from finely chiselled stone blocks arranged in a regular pattern and bound with mortar. The bridge was situated on an important regional road which was a continuation of the old city’s main communication, the decumanus maximus.
Pont Julien ( 43°51’45.33″N 5°18’23.68″E)
The Pont Julien, owning its name to the nearby city of Julia Apta (modern-day Apt), is a beautiful three-arched bridge spanning the Calavon River. Today, it is located close to the town of Bonnieux. It was originally built in 3 BC on the Via Domitia, an important Roman road that connected Italy and Spain through the Roman province of Gallia Narbonensis.
Pont Flavien ( 43°32’29.0″N 5°02’35.0″E)
The Pont Flavien, with its surviving triumphal arches at each end, is one of the most beautiful surviving Roman bridges outside Italy. The Pont Flavien stands near the modern town of Saint-Chamas and consists of a single arch spanning the Toulourde River on the Via Julia Augusta. The name “Flavien” refers to a local Roman-Gaul aristocrat called Lucius Donnius Flavius, and an inscription on the bridge itself states that it was built at his instigation.
