KIZILIRMAK BRIDGE

“... the river is everywhere at once, at the source and at the mouth, at the waterfall, at the ferry, at the rapids, in the sea, in the mountains, everywhere at once, and that there is only the present time for it, not the shadow of the past, not the shadow of the future.”
Hermann Hesse, Siddhartha
The most important factors in bridge design are how the vehicle, tram, pedestrian and bicycle traffic on the bridge will be organized both horizontally and vertically. Vehicle and tram tracks (especially the tram track) need to cross the bridge without too much slope. Therefore, we decided to solve the bridge base at a height that would provide minimum values above the bank and would not hinder pedestrian and vehicle traffic that crosses the riverside and whose continuity is essential under the bridge. The bridge, with a total width of 60 meters, a height of 17 meters and a length of 400 meters, allows vehicle and tramways to cross with very little slope, while allowing pedestrian and bicycle traffic to pass with optimum slope, enjoying the city and nature view.
The span through which the bridge passes from the reinforced concrete shoes is 140 meters. The basis of the design is the concern of obtaining an aesthetic structure that does not need to set foot on the river with the roads carried by two main truss systems over the river. While these scissors form the basis of the carrier system, they also carry the pedestrian and bicycle paths on them. At the road part of the upper level, the noise of the traffic at the bottom is prevented by a wooden deck system and platform. In addition, the polycarbonate elastic-based crash and noise barrier applied on the roadside ensures that the carrier elements of the bridge are not damaged as a result of a possible accident, but it does not prevent the view of the traffic on it. In addition, the actions and platform raised to the upper quota ensure that not only pedestrians but also vehicles passing below interact with the landscape.
