Visiting the Dom Luís I Bridge
An architectural masterpiece
This iron structure, a UNESCO World Heritage site, was built between 1880 and 1886. It connects the city of Porto and the city of Vila Nova de Gaia.
The bridge is an iconic monument in Porto. It stands 45 meters tall and stretches 385 meters long. Resting on a single metal arch, it is recognized as one of the largest and most impressive in the world. It was constructed by the German-born engineer Théophile Seyrig, who was a student of the world-famous Gustave Eiffel. A similar bridge, the Ponte Maria Pia, exists nearby in Porto. It was built by Gustave Eiffel and Théophile Seyrig a decade earlier in 1877. Despite this, it is the Dom Luís I Bridge that inherited the nickname Eiffel Bridge.
A bit of history
Until 1843, you had to take a boat to cross the Douro river to get between Porto and Vila Nova de Gaia. In 1843, a suspension bridge was installed, allowing for much faster travel between the two banks. This suspension bridge was replaced by the Dom Luís I Bridge in 1886, though you can still see two pylons on the Porto side. The Dom Luís I Bridge was specifically commissioned to handle the heavy traffic that was clogging the Ponte Maria Pia.
The Dom Luís I Bridge is named after the king of Portugal at the time. There is a funny anecdote regarding its name. King Luis I was supposed to come to Porto to inaugurate the bridge, but he ended up declining the invitation. The residents of Porto took this as a direct insult and never bothered to correct the plaque on the bridge, which contains a spelling error. You can still read Luiz I instead of Dom Luis I on the structure.
Today, the bridge consists of two levels. The top deck carries a metro line. The lower level is used for vehicle traffic. Note that pedestrians can walk across both levels.
We recommend walking across the bridge to take in the views or sitting on the riverfront docks after dark to watch it illuminated. It is a striking sight.
The impressive structure of this double-decker bridge reminded me a bit of the Bir-Hakeim bridge. Crossing it remains one of my best memories of Porto. It offers superb views of the river and the city. At the foot of the bridge, I took some pretty photos at sunset and at night. When the lights reflect in the water, it is magnificent. I also really liked the surrounding atmosphere. The place is lively and is home to some great street musicians.
