Ponte Maria Pia
Captured from the Douro River during the Six Bridges cruise, this image shows the Ponte Maria Pia, a historic iron railway bridge, now decommissioned and replaced by the modern Ponte de São João in 1991.
No doubt it is a great engineering achievement, but it is also a structure with great aesthetic appeal. As seen in the image, a crescent-moon-like arch beautifully spans the river, with the straight railway deck running tangentially above the arch. As the cruise boat passes by, it is delightful to observe the symmetrical ironwork and its fascinating geometry. Visible behind the Maria Pia Bridge is part of the Ponte do Infante D. Henrique, which, as seen in the image, echoes the arch-and-tangent pattern in concrete.
The bridge was named in honor of Queen Maria Pia of Savoy, wife of King Luís I of Portugal, who attended its inauguration. It is interesting to note that the iconic Dom Luís I Bridge, named after her husband, was completed nine years later.
The bridge was completed in 1877 and designed by the company headed by Gustave Eiffel, the renowned French civil engineer best known for the Eiffel Tower in Paris. At the time of its construction, the bridge was hailed as a major engineering achievement. Interestingly, Théophile Seyrig, who later designed the Dom Luís I Bridge, played an important role in its design. His involvement with the Maria Pia Bridge preceded his work on the Dom Luís I Bridge, where he employed a similarly dramatic iron arch on a considerably larger scale.
Unlike the Dom Luís I Bridge, which has two decks and today carries Metro trains on the upper deck and road traffic on the lower deck, the Ponte Maria Pia is a single-deck bridge built exclusively to carry the railway across the deep Douro valley. Its central iron arch has a span of about 160 meters (525 ft), while the railway deck rises approximately 61 meters (200 ft) above the river.
For more than a century, the Maria Pia Bridge carried trains across the Douro and contributed to the growth of economic activity in the neighboring cities of Porto and Vila Nova de Gaia. However, its single-track structure eventually became a limitation as railway traffic increased. A modern replacement, the Ponte de São João, was therefore constructed nearby and opened in 1991, leading to the decommissioning of the Maria Pia Bridge. Its historic iron structure, however, has been preserved for posterity.
