Halic Metro Crossing Bridge, Istanbul
In August 2010 INPROCON was commissioned with assuming the organization and coordination of preparations for drafting an independent expert report on the visual impact of the Haliç Metro Crossing Bridge with regard to Istanbul, Turkey as a World Heritage Site.
The independent preparation of the expert report with a positive outcome for the construction of the modern bridge preserving the status of the World Heritage Site was successfully completed with a team of experts from Germany and Great Britain.
The Haliç Metro Crossing Bridge connects the metro line Yenikapı–Taksim in the historical center of Istanbul across the 80 m deep Golden Horn (Haliç). The overall length of the bridge is approx. 1,000 m, and the main element is planned as a cable-stayed bridge with two pylons having a height of 65 m above the bridge deck. The total length of the cable-stayed bridge is 390 m and spans the main field with a length of 180 m. The new Unkapanı metro station is located in the middle of the bridge. An integrated swing bridge with a length of 120 m is planned, to also allow large ships access to the Haliç. Both constructions, the cable-stayed bridge and the swing bridge, are built with structural steel. The approach bridges consist of prestressed concrete constructions.
