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. At 1,560 metres, it carries six lanes of motorway traffic across the strait. Its dramatic setting, strung between two ancient continents and illuminated at night, makes it one of the world's most dramatic bridge experiences.
