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 by which enabled the Romans to erect structures of great beauty and solidity. Most utilised concrete which the Romans were the first to use for bridges. 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 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.

The Pont Tibère (Tiberius Bridge) is a Roman bridge crossing the Vidourle river in Sommières in the Gard department. It was built under the reign of Tiberius on the Via Luteva linking Nemausus (Nîmes) to Tolosa (Toulouse). It initially consisted of 17 arches, of which only 7 are now visible. It had a total length of 190 meters. During the Middle Ages, numerous arches were absorbed into the city’s structure. Today they serve as cellars.
Roman Bridge at Vaison-la-Romaine ( ) 44°14′20.24″N, 5°4′28.88″E
The Roman bridge at Vaison-la-Romaine was built in the first century BC. It spans the Ouvèze River, linking the lower part of the city to the upper medieval part of town. The bridge is unique due to its semicircular 17 meters arch.
Pont Ambroix ( ) 43°43′1.92″N, 4°9′6.84″E
The Pont Ambroix or Pont d’Ambrussum was a 1st-century BC Roman bridge which was part of the Via Domitia. The Ambroix Bridge is unquestionably the most spectacular ruin of Ambrussum, a Gallo-Roman archaeological site which has revealed an exceptional collection of buildings from the Gallic and Roman periods. The Pont Ambroix is an impressive work of engineering, which allowed the Via Domitia to cross the Vidourle River. It is thought to have had 11 arches and to have been over 175 meters in length.
Pont Romain de Viviers ( 44°29’18.2″N 4°40’19.4″E)

The Roman Bridge of Patras was constructed between the 2nd and 3rd century AD over the Kallinaos river which flow has moved 100m further south. It is a part of a complex of two smaller bridges; a single-arched one and a two-arched bridge constructed later. It is considered to be the best preserved bridge of its type in Greece. It was part of the public road that connected Patras and Aigio. The road that goes over the bridge was paved with stone-slabs in which the wheel-tracks (armatotrohies) made from the chariots are still visible. On both sides there were low walls for the protection of the pedestrians.
Roman bridge at Beth-She’an ( 32°30’25.6″N 35°29’44.6″E)
The ruins of the Roman bridge, a triple arched bridge crossing the Nahal Harod, Scythopolis (Beth-She’an).

Ponte de Vila Ruiva presents several construction phases. It is assumed that the original structure, made of granite, dates back to between the 1st century BC and 1st century AD. Reconstructions on the bridge were undertaken in the 5th century and 11th century, using ancient and new materials. Ponte de Vila Ruiva is still in use today.
Ponte dos Três Concelhos in Ribeira da Isna ( 39°44’08.0″N 8°03’18.0″W)
The Ponte dos Três Concelhos, spanning the river Ribeira de Isna, is a three-arched Roman bridge. This bridge was part of a Roman road that connected Augusta Emerita (Merida, Spain) to Conimbriga. It was probably built between the 1st and the 4th century and rebuilt between the 13th and the 14th century.
Ponte Romana de Idanha-a-Velha ( 39°59’43.8″N 7°08’31.6″W)
On the banks of the river Pônsul, ca. 50 km from Castelo Branco, the Roman town of Igaeditania (Idanha-a-Velha) became a municipium in the time of the Flavians. A road from Augusta Emerita to Igaeditania run across the Roman bridge crossing the Pônsul which seems to have been constructed in 5 or 6 AD, when Augustus set the limits of the civitates of the region. Igaeditania was thus an important road center. The bridge was reconstructed several times across the centuries. What we see now is mainly the result of a reconstruction from Middle Ages.
Roman Bridge at Miróbriga ( 38°00’36.5″N 8°41’04.1″W)
At Mirobriga Celticorum, a Roman town located south-west of Portugal near the coast, lay a small single-arch bridge that provided access along the west-east road leading to the forum and the Imperial temple of the Roman town. The bridge was made of irregular limestone, opus incertum. The original paving of the bridge is still visible.
Roman Pier Bridge of Myrtilis in Mértola ( 37°38’08.7″N 7°39’51.1″W)
In Mértola (Roman Myrtilis), an important ancient port on the River Guardiana, stand the remains of imposing piers of a bridge lined up in the late Roman period to give access to a River Tower. The tower controlled one of the most important entries into the city. An access route, built on a solid series of arches, allowed the tower to connect with the interior of the City Walls.
Puente romano de Monforte ( 39°03’26.2″N 7°26’39.4″W)
This seven-arched Roman granite bridge spans the Ribeira Grande river. It was part of two Roman state roads, the 325 km long via publicae from Olisipo (Lisbon) via Aritium Vetus (Alvega) to Emerita (Spain, Mérida) and the 230 km long via publicae from Olisipo (Lisbon) via Abelterio (age Do Chão) to Emerita (Spain, Mérida). This bridge is commonly named as “Roman”, yet several architectonic details indicate a more recent construction, probably built over a Roman construction and re-utilizing Roman materials.
Roman Bridge over the Albarregas River in Mérida ( 38°55’25.9″N 6°20’57.0″W)
Built when the Roman city of Emerita Augusta was founded, the bridge on the Albarregas River is still in perfect condition. It has four granite ashlar arches, with two wider arches which are the overflow channel of the aqueduct. It is parallel to Los Milagros aqueduct.
Roman Bridge over the Guadiana River in Mérida ( 38°54′47.02″N, 6°21′2.99″W)
The Roman bridge over the Guadiana River at Mérida is the world’s longest surviving bridge from ancient times, having once featured an estimated overall length of 755 m with 62 spans. Today, there are 60 spans (three of which are buried on the southern bank) on a length of 721 m between the abutments. Including the approaches, the structure totals 790 m. It is still in use, but was pedestrianized in 1991. The layout and most of the primitive manufacture were carried in the time of Augustus and was renovated at different times.
Puente de Carmona ( 37°28’34.8″N 5°37’28.7″W)
The Roman bridge at Carmona, which consists of five arches, is still in use today thanks to various renovations over the years. Surrounded by green, rolling hills, this excellent example of Roman engineering sits along the ancient Via Augusta, a Roman commercial route that snaked along the east coast of the Iberian Peninsula.
Roman Bridge of Córdoba ( 37°52’37.2″N 4°46’42.1″W)
The Roman bridge of Córdoba is a bridge originally built in the early 1st century BC across the Guadalquivir river, perhaps replacing a previous wooden one. The bridge has been reconstructed at various times since and most of the present structure dates from the Moorish reconstruction in the 8th century.
Puente romano de Villa del Rio ( 37°59’13.5″N 4°16’15.6″W)
The Roman Bridge of Villa del Río spans the stream Salado de Porcuna a few kilometers from its mouth in the River Guadalquivir. From its construction in the 1st century AD (although there are doubts about its exact chronology) it gave continuity to the Via Augusta. The bridge, built in opus quadratum, was in use until 1965.
Puente Romano de Andújar ( 38°01’56.6″N 4°03’42.9″W)
The Bridge of Andújar is a Roman bridge located to the exit of Andújar, province of Jaén (Spain). It is a bridge of great historical value and crosses the river Guadalquivir. It was built in the beginning of the 3rd century AD and, since then, it has been an essential communication route of the valley of the Guadalquivir river. Nowadays it is a bridge with 14 hollows, and barrel vaults. The bridge has a total length of 310 m. It has three alignments, the central one still being originally conserved from Roman times. Due to its current use, its state of conservation is inadequate.
Puente romano sobre el arroyo Pedroches (Córdoba) ( 37°54’14.73″N 4°45′ 22.28″W)
The Roman bridge over the Pedroches stream in Cordoba was probably located on the road which linked Córdoba and Merida. It was built between 27 and 81 AD. The bridge consists of three semicircular arches measuring 4.75 m (central arch) and 2 m (sides arches).
Eurymedon Bridge near Aspendos ( 36°54′51.23″N, 31°9′46.79″E)
The Eurymedon Bridge was a late Roman bridge over the river Eurymedon (modern Köprüçay), near Aspendos, in Pamphylia. The foundations and other stone blocks (spolia) of the Roman structure were used by the Seljuqs to build a replacement bridge in the 13th century, the Köprüpazar Köprüsü, which stands to this day. This bridge is characterized by a significant displacement along its mid-line, noticeable by looking at its ancient piers. Originally, the bridge had a length of 259.50 m and a width of 9.44 m, and had nine semicircular arches.
Eurymedon Bridge near Selge ( 37°11’31.2″N 31°10’51.6″E)

The Nysa Bridge is a late imperial Roman bridge over the Cakircak stream in Nysa in the ancient region of Caria. The 100 m (328 ft) long substructure was the second largest of its kind in antiquity, after the Pergamon Bridge. It was built as a two-level structure: the bottom vault spanned the brook. It consists of a single, 5.7 m (19 ft) wide vault whose uphill mouth widens to 7 m (23 ft).
Chesters Bridge on Hadrian’s Wall ( 55°01’31.2″N 2°08’08.0″W)
Chesters Bridge was a Roman bridge over the River North Tyne at Chollerford, and adjacent to Chesters Roman fort on Hadrian’s Wall. A shift in the course of the Tyne has moved the river westwards about 20 m, completely covering or sweeping away much of the west abutment, leaving the eastern abutment high, if not always dry, on the other bank.
Willowford Roman Bridge on Hadrian’s Wall ( 54°59’28.9″N 2°35’31.8″W)
On the east bank of the River Irthing stand the remains of a Roman bridge built on the line of Hadrioan’s Wall. The bridge is now completely on dry land, and a modern footbridge takes walkers across the river and along an extremely well-preserved section of Hadrian’s Wall to Birdoswald Roman Fort a short distance away. Willowford bridge was built as part of Hadrian’s Wall, around 122 AD. The bridge was built in two phases; the first was fairly narrow, and is represented by the abutment and foundations on the east shore. Nearby is a huge pier which helped support a second, wider bridge.
