Osman Gazi Bridge

The bridge will be located at the eastern end of the Sea of Marmara, close to İzmir and approximately 50km from Istanbul, Turkey. It will be the second largest suspension bridge in the world by length of central span. Crossing the Bay of İzmit, the bridge (and connecting highway) will provide 3 lanes of traffic in either direction. The total length of the bridge is 2.8 kilometres, with a main span of 1,500 metres.

The design will ensure that the completed bridge will be a work of high aesthetic integrity, and a striking feature within the local landscape and seascape. Its constituent components harmonize well with one another in terms of their geometric configuration, colour, and finish.

The bridge girder, with its delicate and aerodynamically refined deck edge, will be perceived as an elegant ribbon of motorway suspended above the water, before transitioning over the transition piers and approach spans to land.

Transition piers and anchor blocks relate well aesthetically to one another and to the bridge as a whole, and serve to reinforce the aesthetic lightness and elegance of the span.

Motorists crossing the bridge will be afforded beautiful views of the simple, yet characteristic towers, and their views toward the surrounding hills and landscape will not be impeded or blocked by the very transparent windscreen structure.

 

Osman Gazi-broen

Broen skal placeres i den østlige ende af Marmarahavet, tæt på byen Izmir og cirka 50 kilometer fra Istanbul. Broen vil være den næststørste hængebro i verdenen med et hovedspænd på 1,500 meter. Broen, der skal krydse Izmitbugten og forbindes med motorvejen, vil give mulighed for tre baners trafik i begge retninger. Den totale længde af broen er 2,8 kilometer.

Den er designet ud fra et ønske om en høj æstetisk integritet samt ønsket om at være et landmark i det landskabet. 

Broens kantbjælke med sin aerodynamiske form og opbygning, vil blive opfattet som et elegant bånd svævende over vandet. Bropillerne og ankerblokkene relaterer sig æstetisk til hinanden og til broen som en helhed, og styrker letheden og elegance af spændet.

Bilister, der krydser broen, vil få en smuk udsigt til de enkle, men karakteristiske tårne, og udsigten over det omkringliggende bakkede landskab vil ikke blive generet eller blokeret grundet den transparente vindskærm.
