The Maria Pia Bridge is in the background. And this bridge is in the background of some of the photos of that bridge.

| WanderLog "Ponte Infante Dom Henrique is a modern elevated road bridge in Porto, inaugurated in 2003. It pays homage to Prince Henry the Navigator and is known for its contemporary slim profile and stunning views across the Douro River. Designed by Adao da Fonseca and Francisco Millanes Mato, this iconic structure features a 280-meter concrete arch span, reaching a height of 72 meters." |

| behindagreatproject "Achieving visual transparency implied placing the arch bases as high as practical up the riverbanks, which drove the 280 m main span and the relatively small arch rise of about 25 m. The resulting arch span-to-rise ratio of 11.2 exceeds the historic range of between 6 and 10. The arch itself has a constant thickness of 1.5 m, resulting in the record-setting slenderness of 186.7 – the conventional range falling between 40 and 90. Instead of curved profile, the arch follows a polygonal longitudinal profile with subtle kinks at each link pier, nearly approximating the antifunicular of the dead loads." Most arch bridges have a stiff arch and a flexible deck. This bridge has a flexible arch and a stiff deck. That is, the big box-girder deck helps carry the loads. |
This photo provides a better view of the support and cables that provided the falsework during construction.

Removing the supports was a non-trivial operation in its own right.
