This thesis describes the construction of Babina Rijeka Viaduct which is part of the Zenica bypass project – corridor Vc, subsection: Klopče – Donja Gračanica. The paper is based on the experience and knowledge gained during the student internship at the subject location and project documentation. The specificity of this project is the construction of extremely high columns and the use of free cantilever construction on a span construction. The construction of foundations, pillars and span structures of the bridge are presented, and each phase of construction as well. The procedures that must be followed before the bridge is constructed are described, as well as the basic design requirements, the solution for the layout of the building and the choice of construction technology. The geotechnical features of the soil and the choice of excavation methods at the site are given. The stages of construction are described below: the choice of foundation types, the construction method of piers, zero segments of the span structure, as well as the span construction itself. For each phase, the installation of the planking, metal framework and the concreting of the construction are explained. Considering that the construction of the viaduct is still in progress, a detailed representation only of completed elements is given. The part of the construction that is not fully completed (the junction segment of the span construction) is based on the project documentation.
