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 Weight 3045 tons The arch measures 172 m in length and 44.6 m in height note:All my pictures are copyrighted and belong to me.
