Ponte de São João: Modern Railway Bridge over the Douro

Ponte de São João
Captured from the Douro River during the Six Bridges cruise, this image shows the Ponte de São João, the modern railway bridge that replaced the historic Ponte Maria Pia. As seen in the image, its railway deck stretches across the valley on tall, slender reinforced-concrete piers rather than being supported by a large arch.

Designed by renowned Portuguese engineer Edgar Cardoso, who also designed the Ponte da Arrábida, the São João Bridge was inaugurated in 1991. The bridge is 1,140 meters (3,740 ft) long and carries two railway tracks. Its 250-meter (820 ft) central span established a world record for this type of bridge when it opened in 1991.

It was constructed to replace the neighboring Maria Pia Bridge, whose single railway track and 19th-century structure could no longer cope with the demands of modern rail traffic across the Douro.

During the boat ride, the contrast in design and appearance between São João and the nearby Maria Pia Bridge it replaced is unmistakable. From this viewpoint, the Ponte de São João appears almost superimposed on the elegant Maria Pia Bridge. The stark concrete structure is an eyesore when seen against the graceful iron arch of its predecessor. Looks aside, however, the new bridge brought enormous practical and economic benefits to the region by replacing the Maria Pia Bridge’s single track with two railway tracks, allowing more frequent and faster train services across the Douro.
