Porto at nite is stunning. One of the better views of the city can be from the Luis Bridge. In the middle of the bridge railway cars travel in each direction. Walking paths are on either side. This shot above is from walking across at nite and enjoying the view ahead.
Info from the web: The Luís 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. Téophile 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.
