For the bridge structure on the D3 Motorway Čadca, Bukov – Svrčinovec project, we carried out the fabrication and installation of the steel load-bearing structure forming an important part of the modern transport connection in northern Slovakia. The project contributed to improved traffic safety and smoother transport flow in the region while diverting transit traffic away from the urban area of Čadca.
The scope of works included the fabrication of the steel bridge structure, including assembly blocks and additional structural steel components. The entire solution was designed with emphasis on high load-bearing capacity, structural stability, and efficient installation while meeting all required technical parameters. The steel load-bearing structure consists of nine plate girders connected by end crossbeams. The main structural system of each bridge is formed by continuous I-shaped plate girders. In the cross-section, the structure comprises a total of nine girders grouped into assembly blocks of three girders each. The girder webs are reinforced with vertical stiffeners ensuring the required rigidity of the structure. The load-bearing structure is supported on reinforced concrete abutments whose width corresponds to the variable width of the bridge. The substructure consists of end abutments on which the structure is supported by sets of three bearings. The bridge foundation was designed as a deep foundation using large-diameter piles.
The realization of the project required precise fabrication of individual steel components, coordinated assembly procedures, and a high level of technical accuracy throughout the entire construction process.
Technical parameters:
Weight of steel structure: 198 tons / Length of steel structure: 48.24 m / Total value of completed works: € 868,920
