Bosphorus Bridge (July 15 Martyrs), Istanbul

The first Bosphorus Bridge, opened in 1973, was the first bridge to connect Europe and Asia and remains one of the most symbolically loaded crossings in the world, carrying six lanes of motorway traffic across the strait. At 1,560 meters, it is 300 meters longer than #8 Rialto Bridge's total length (about 48 meters). Its dramatic setting, strung between two ancient continents and illuminated at night, makes it one of the world's most dramatic bridge experiences.
