The Ponte Luís I with an Eurotram seen from the Escadas de Guindais.
The Ponte Luís I was inaugurated in 1886 and designed by Théophile Seyrig, the former partner of Gustave Eiffel. In 2003 the Ponte do Infante was opened as replacement for the road traffic on the upper deck. The Ponte Luís I got a major overhaul and the upper deck is since 2005 used by the trams of the "Metro do Porto". Pedestrians are allowed to use the upper deck, but all road traffic is abandoned. The lower deck is still used by road traffic.
