Bosphorus Bridge

The Bosphorus Bridge (Bogazici Koprusu) in Istanbul is one of three continent-spanning bridges over the Bosphorus Strait, connecting Europe and Asia. When it opened in 1973, the 5,118-foot (1,560-meter) bridge was the fourth-longest suspension bridge in the world. And though it has since slid down the rankings, it is still an impressive sight to behold.
