The thesis shows the course of process from design to dimensioning of the steel cable-stayed bridge over river Krka in Irča village. The superstructure is designed as a space-truss made up from cold formed circular sections, which horizontal path takes place as an »S« curve and is supported by assymmetricly positioned cable-stays on the outer radii of the »S« curve. The load from superstructure is transfered trough the cable-stays onto two pylons. Main effects on the bridge are specified accordingly with the european standards the Eurocodes, by which the static and seismic analysis was calculated.
