Desire of large span selection is closely related to geological and topographical features of the sea bottom. The bedrocks are about 15 meters to 20 meters deep in the sea. Thus, they lead to reduce the number of pier as much as possible and place in shallower parts. “Free balanced cantilever method” has been selected as a construction method because it is not possible to base scaffolding at offshore.

Project : Yakakent - Gerze Highway Project Location : Sinop Service Period : 2009 - 2011 Client : General Directorate of Highways Scope of Service : Detailed Design, Survey and Design Services Bridge Type : Highway - Steel - Concrete Superstructe Type : Steel I-Beam + Concrete composite deck Total Length : 865 m (A - Bridge), 885 m (B - Bridge) The Longest Span : 70 m Bridge Width : 2 x 14.25 m 19 Sinop İdemli Viaduct İdemli viaducts (1, 2.1, 2.2 and 3) have required a special structure design because of landslide having 20 m depth in the bridge area. A structure design has led to large spans without block of the landslide as much as possible. A composite superstructure has been selected consisting of four I-beams and cast in place deck because of ease of construction and road profile. The superstructure system is continuous. 165 cm diameter steel armored bored piles have been used to withstand landslide effects.
