Dom Louis I Bridge – Porto, Portugal

The Dom Luís I Bridge is a double-deck metal arch bridge that spans the River Douro between the cities of Porto and Vila Nova de Gaia in Portugal. At its construction, its 564 ft span was the longest of its type in the world. It has been confused with the nearby Maria Pia Bridge, a railway bridge that was built 9 years earlier and is similar in aspect to the Luís I bridge.
One of the notable features of the Dom Luís I Bridge is it’s two levels; one on top of the arch and the other suspended below it. Both decks were initially intended to carry road traffic but these days the top carries the Porto Metro trains as well as having a pedestrian walkway.
