Da Vinci'nin Haliç Köprüsü

"Leonardo da Vinci'nin had a vision in 1502:To construct the largest and most beautiful ridge that has ever been seen in the world.”

 

“In 1502, the Sultan Bajazet II decided he needed a bridge. He commissioned none other than Leonardo da Vinci himself to design the bridge. Leonardo's design was strange in the extreme: a stone bridge in a single graceful arch, thin at the centre and widening both horizontally and vertically at the ends to join onto the land in a series of curves; the design is organic-looking and resembles the roots of a tree. The whole style of the bridge is a triumph of minimalism, totally unlike the baroque masterpieces popular in Europe at the time.

Some details of Leonardo's design:

Width at centre: 24m
Height above sea at centre: 40m
Span: 240m
Total bridge length: 360m

We don't know the Sultan's reaction to Leonardo's plans, but the bridge was never built.”

Da Vinci’s design used the technology of his era. On the other hand, use and form of structural building components at a level far beyond its era is matchless. Two main carriers are observed in the arc form passing a space of 360m. Circulation platform stands on these main carriers.
The starting point of our project is to preserve the original design conceptually; to explicate is structurally and in terms of material use. The main carrier carrying the main body has been established with pre-stressing steel girders. These girders separate from the main body on both sides and are fastened on the ground. The main structure on steel carriers sits on a base behind and this permits pedestrian and vehicle circulation from under the structure. The main body except for arc shaped steel carriers are covered with sandstone, the seating groups and barriers are made of massive wood. Linear illumination emphasizes the whole structural components.
The bridge physically connects the two coasts and aims at brightening up social life. In this manner, it is aimed to relate Miniaturk and the social activities foreseen in the southern coastal part with the ridge. There is a rowing and water sports club, eating facilities such as cafes and restaurants and recreation areas supporting these functions on the historical peninsula.

Although the Da Vinci Bridge missed the opportunity to become one of the symbols of Istanbul, which has been the capital of the Byzantine and Ottoman Empires, it still carries the hope of being the modern symbol of a world city in terms of social and economic perspectives in which many cultures live together.

Da Vinci'nin dizaynına dayanan küçük bir köprü(1:6 oranında) Norveç'te Aas yakınında inşa edildi (2000).
