Luiz I Bridge
Two decks, one Douro crossing — the upper carries Metro line D while the lower lands you at the Ribeira waterfront.

Its 172-metre arch was the longest metal arch span in the world when built. Gustave Eiffel entered the competition and lost; his former partner Théophile Seyrig won with this double-deck design. The upper level reaches São Bento station and Porto's city centre; the lower deposits you at Gaia's Port wine lodges on the south bank.
What to look for
- Metro line D trains sharing the upper deck with pedestrians — the rail and foot traffic run at the same level above the gorge
- The Maria Pia Bridge 1 km to the east — a railway bridge Seyrig also designed, built nine years before this one and similar in silhouette
- Port wine lodge signs on the Gaia waterfront at the southern end of the lower deck
Upper deck connects São Bento station (north) to Serra do Pilar Monastery and the Gaia Cable Car upper station (south); lower deck connects Praça da Ribeira and the Guindais Funicular (north) to Gaia's waterfront (south).
