With a main span of 2,023m, completion of the suspension bridge will open a new category for the world’s longest span bridges, being the first in the world to have a main span of more than 2km. It is being built at the western end of the Sea of Marmara, some 200km from Istanbul, and, like the country’s three bridges crossing the Bosphorus Strait, will also straddle two continents, connecting the Asian and European parts of Turkey.
