The Daily Post Weekly Photo Challenge for the week of May 17, 2017.

The D. Luis I Bridge (road bridge crossing Douro River at Oporto, Portugal) planned by the engineer Théophile Seyrig, a disciple of famous Gustave Eiffel was inaugurated in 1886. The bridge has 395 metres long and 8 metres wide, and its arch is still considered to be the world’s biggest one in forged iron.

In 1982, the bridge was designated a cultural heritage.
