The thesis deals with the design, static analysis and dimensioning of a steel footbridge bridge over the Sava River in Radeče with a span of 100 m. In designing the bridge, we produced an idea to create an arch bridge over a deck construction. The thesis also contains an analysis of loads and their combinations for the ultimate limit state and serviceability limit state. It is important to note that dynamic influences of wind and earthquake were excluded from the analysis. We conducted a static analysis and element dimensioning. The elements were dimensioned using the Scia Engineer software according to the calculated internal forces. The construction of the bridge was slender. As a result, the serviceability limit state in the dimensioning process was more problematic than the ultimate limit state. Natural frequencies of the bridge were not within the recommended limits. To this end, a more detailed dynamic analysis of the bridge would be necessary.
