Porto slopes down from a height to the Douro river and comes to an end at the river bank. The river separates it from Vila Nova de Gaia, a town known mainly for its warehouses of Port wine. Five bridges cross the river from Porto. On our first evening in the town, we decided to take a cruise along the river and under the bridges.
The westernmost of these is the Arrabida bridge (photo above), completed in 1963. The single arch across the river was once the longest in the world. This was one of the two works of Edgar Cardoso, one of Portugal’s iconic engineers, which we saw. The deck of the bridge, and the traffic it carries, passes high over the boat. Porto stretches even further to the west, right to the shores of the Atlantic. As the boat passes beyond the bridge, you see the river widening out, and Vila Nova de Gaia coming to an end. The river cruise turns around well before coming to the ocean.
Dom Luis 1 bridge (featured photo) is the iconic bridge of Porto. The double decker bridge was completed in 1887 and had a record arch span at that time. The bridge was designed by Teophile Seyrig, who had earlier worked with Gustave Eiffel. The upper deck was strengthened by Edgar Cardoso a century later. We saw trams crossing the upper deck. All other traffic crosses along the lower deck. As we passed below it we saw three other bridges lined up ahead.
The next bridge up river was the Ponte Infante Dom Henrique (photo above). It was completed in 2003 by Antonio Adao da Fonseca. I admired the clean modern lines of this concrete bridge as we passed below it. Beyond this were a pair of railway bridges.
The Ponte Maria Pia (photo above) was the first of Porto’s bridges. Gustav Eiffel’s engineering company, then little known, designed and completed it in 1877. Teophile Seyrig, who then worked for the company, is usually credited with having designed it. At that time it was the longest single arch bridge in the world. It was superseded in 1991 by the bridge we passed under next. This is the concrete Ponte de Sao Joao (photo above), designed by Edgar Cardoso, and completed in 1991.
The boat ride lasted about an hour. Interestingly, there are no explanations or commentary during the ride. You see what you want to see. Fortunately, I had taken the time to read up on the bridges before, so I could appreciate them. There must be much along the river which I missed. I am not a fan of continuous commentary, but it would be nice if there was a cruise which could point out the main structures of interest as we passed them.
