The Dom Luís I Bridge (Portuguese: Ponte Dom Luís I or Ponte Luíz I) is a steel arch bridge across the Douro River, connecting Portugal's second-largest city, Porto, with Vila Nova de Gaia. It was named in honor of King Louis I at that time. In 1996, the Bridge of Louis I was inscribed on the World Heritage List, together with the Porto Historical Center and the Monastery of Mount Pilar.
In the second half of the nineteenth century, commerce in the city of Porto was developing. There is an increase in traffic demand between Vila Nova de Gaia and Porto, but there is no suitable bridge to fasten them. In 1879, the government decided to open a tender for the construction of a metal bridge; it would replace the drawbridge at the most convenient location in front of the city of Porto.
After everything was settled, the construction of the Louis I Bridge began in 1881, with the bridge's inauguration on October 31, 1886. Since then, the traffic and trade between Porto and Vila Nova de Gaia have bloomed over the decades. You will find out more details about the incredible design and size of the Dom Luís I Bridge.
Description of The Dom Luís I Bridge Size
The Ponte Dom Luís I is located in the center of Porto, spanning the Douro River to link the old city and the new city of Gaia. It was built in 1886 by the apprentice of designer Alexander Gustave Eiffel. The outstanding engineer, Théophile Seyrig from the Belgian company Société de Willebroeck, took down the project. He was the head of the design team of the D.Maria Pia Bridge project, another famous bridge in Porto, and an apprentice of Gustave Eiffel, the designer of the Eiffel Tower.
The Dom Luís I Bridge has been open to the public since 1886 and reflects the sophistication of typical European architecture. The bridge has two large arches, and the two lanes are divided into two levels. The subway track is laid on the upper floor. Thousands of vehicles and passengers pass over the bridge every day.
Length and Height of the Dom Luís I Bridge
The Ponte Dom Luís I was the largest arch bridge in Europe, spanning 172 meters until 1898. The bridge has a height of 44.6 meters (146 feet) above the water. The top level carries the Porto Metro trains and has a pedestrian walkway. It is worth making the crossing on the upper level at 60 meters (190 feet) above the waters of the Douro. Two decks vary in length; the lower deck is 172 meters (564 feet) long for cars and pedestrians, and the upper level is 395.25 meters (1,296.8 feet) long. It is only 8 meters wide between pedestrian walkways.

After more than 120 years of wind and rain, the bridge is still in use. Although it is made of steel, its structure is smooth and flexible, and it is a landscape from any angle, like the Eiffel Tower lying on the Douro River. The Dom Luís I Bridge has also become the most eye-catching gem on Porto's postcards. There are many ways to visit the Dom Luís I Bridge. You can take a sightseeing boat on the Douro River to admire the bridge's grandeur or enjoy a meal at the riverside restaurant while watching the bridge gleaming in the sunset.
