The bridge was commissioned by the citizens of ten local 'civitates' as evidenced by the Latin inscriptions on the surviving votive pillars.
The structure original spanned 150 meters, though modern urban development has partially obscured some of its approach ramps.
Excavations have revealed that the foundations sit directly upon the riverbed's granite bedrock for stability.
The bridge is categorized as a National Monument of Portugal since the early 20th century.
One of the two original inscribed pillars is still positioned near the northern end of the bridge to signify its historical significance.
The Trajano Bridge, also known as the Ponte Romana de Chaves, is an ancient stone arch bridge spanning the Tâmega River in Chaves, Portugal. Constructed during the reign of Emperor Trajan around the 1st century AD, it was designed to connect the Roman cities of Bracara Augusta and Asturica Augusta. The structure features 12 semi-circular arches built from local granite, with several original Roman inscriptions remaining on the pillars. Two inscribed pedestals, known as the 'Padrões dos Povos', commemorate the tribute paid by regional tribes for the bridge's construction. Throughout its history, the bridge has survived numerous floods, including the destructive floods of the 18th century. It remains an active thoroughfare, allowing pedestrian and light vehicular traffic to pass between the historic center and the riverbank. The bridge stands as one of the best-preserved examples of Roman civil engineering in the Iberian Peninsula.

Walk the full length of the bridge to observe the masonry changes between the Roman base and later medieval repairs.
Visit the nearby Museu da Região Flaviense for context on the Roman archaeological findings in the area.
Cross during the golden hour to see the sun reflect off the granite arches and the calm Tâmega River.
Do not attempt to drive across during peak pedestrian times, as the lanes are narrow and primarily suited for local traffic.
