Taşlıgüney 2 Viaduct is a balanced cantilever highway bridge with a total length of 573 meters in 8 spans and a height of 120 meters at the deepest, located on the Erzurum-Kars Highway, being built with the incremental launching method with 4 middle spans. The balanced cantilever middle piers of the bridge are constructed monolithic, and the side piers are connected to the approaches by spherical abutments with anti-uplift guided spherical bearings. The spherical bearings on the side piers, which will withstand 25000 kN compressive and 8500 kN tensile force, as well as exhibit a maximum displacement of ±1000 mm during the maximum credible earthquake, have been manufactured by TIS Teknolojik İzolatör Sistemleri, and their site installation continues.
