El principal símbolo de Oporto al atardecer y de noche
One of the most iconic sites in Porto, Luis I Bridge is designed by the engineer Théophile Seyrig, a disciple of Eiffel. The bridge was inaugurated in 1886 and it is composed by two overlapping iron decks. The bridge is 395 metres long and 8 metres wide, and its arch is considered, until 2017, the world’s biggest one in wrought iron. Nowadays the upper deck is used by Greater Porto’s Metro, connecting the Cathedral’s area in Porto to Jardim do Morro and to Avenida da República in Vila Nova de Gaia.
Luís I Bridge is a double-deck metal arch bridge that spans the River Douro between the cities of Porto and Vila Nova de Gaia in Portugal. (Wikipedia)
