The Luís I Bridge (Ponte Luís I) is a metal arch bridge that spans the
Douro River between the cities of Porto and Vila Nova de Gaia in
Portugal. At the time of construction its span of 172 m was the
longest of its type in the world.
The Government held a competition for the construction of a metallic bridge over the Douro River on a site that was adjacent to an existing bridge and would replace it. Teófilo Seyrig had already engineered the D. Maria Pia Bridge project nearby, whilst working as a partner of Eiffel. He now took sole responsibility for the new, major Luís 1st Bridge. The construction was begun in 1881 and the bridge opened on 31 October 1886.
Total length 385.25 m
