Bridge of Eiffel
Viana do Castelo
The Bridge of Eiffel, also known as Ponte Rodo-Ferroviária de Viana do Castelo, is a remarkable multi-level metallic structure spanning the Lima River in northern Portugal. Designed by the famous engineer Gustave Eiffel, it combines both road and railway transport, with a road deck on top and a railway deck below. The bridge stretches approximately 645 meters in length and is supported by eleven masonry and stone pillars, some of which are located on the riverbanks. It consists of ten continuous straight beam spans and is notable for its multiple hinge girders, showcasing advanced 19th-century engineering. This bridge is considered a monumental work and a symbol of iron architecture in Portugal. It connects the northern parishes of Viana do Castelo and Meadela with Darque on the southern bank, facilitating both vehicular and rail traffic on the Linha do Minho and National Road 13. The structure is a candidate for classification as a National Monument, reflecting its cultural and historical importance. Its design and construction illustrate the transition from traditional wood and stone bridges to modern metallic engineering, making it a unique landmark in the region.

History
The site originally featured a wooden bridge built between 1818 and 1820, replacing ferry crossings that had served Viana do Castelo for centuries.
Increasing transport demands and the rise of railways in the 19th century led to plans for a more durable and functional bridge.
In the mid-1800s, engineers including John Rennie proposed replacing the wooden structure with a stone or metallic bridge to improve navigation and transport efficiency.
Ultimately, Gustave Eiffel designed the current metallic multi-level bridge, constructed in the late 19th century to carry both road and rail traffic.
Over time, the bridge has become an iconic symbol of iron architecture in Portugal and remains a vital transportation link in the region.
