If one had but a single glance to give the world, one should gaze on Istanbul. ~Alphonse de Lamartine
Istanbul – Bosphorus and the 3rd bridge
The view of Bosphorus and the 3rd bridge. Designed by the Swiss engineer Jean-François Klein (project leader) and by the French structural engineer Michel Virlogeux from T-ingénierie (a Geneva-based company). The height of its towers are 322 meters (1,056 ft). So, it is one of the tallest bridges in the world. It is, after the Millau Viaduct, the second-tallest bridge in the world of any type.
Istanbul is the only city in the world sit across two continents. It straddles both Europe and Asia, while the Bosphorus separates the two continents. The Bosphorus or Bosporus, also referred to sometimes as the Istanbul Strait (Turkish: İstanbul Boğazı), is a strait that forms part of the boundary between Europe and Asia. It is 31 kilometer (19 miles) long waterway that connects the Black Sea with the Sea of Marmara.
