Our projects

The bridge reconnects the Malatya Plain, divided in two by the Karakaya Dam, and was designed for incremental launching. Its superstructure is a steel-concrete composite twin girder; because of the bridge's proximity to an active fault, viscous seismic dampers were designed at both abutments. Its completion established continuous dual-carriageway road between Malatya, Hekimhan and Sivas.
