Abstract: Special vertical geodetic network was established on the viaduct Koševo. Measurements in the network were performed by using precise geometric leveling in two epochs. Measurements in the first epoch were done in winter conditions, while the second epoch measurements were done in summer conditions. Processing and network adjustment was followed after the measurements. The heights of characteristic points on the bridge resulted from mentioned procedure. Taking into account the standard deviation of measurements, differences in heights of points on the bridge have shown change in the height of individual points on the bridge. These differences suggest possible movements of the pre-stressed concrete viaduct Koševo.
