Second Bosphorus Bridge 1988
Bridging Two Continents
The towers were erected on hills either side of the Bosphorus using a large crawler crane to lift the component parts.
The erection of the towers (74 panels, 28,000 high-strength bolts and 350 tension bolts for each tower) was completed in about two months, by the end of October 1986.
Each of the towers of this suspension bridge consists of two legs and two portal beams. The tower blocks are joined entirely on the inside of the blocks, eliminating the need for any work at the outside of the tower.
This contributes not only to safe, speedy work, but also to the aesthetic appearance of the tower.
