The paper presents the results of geodetic monitoring of a reinforced concrete bridge that spans 47.58 m over the Lybid River in Kyiv. Based on GNSS observations and geometric leveling, we determined the vertical alignment of the longitudinal axes of eight main girders. Detailed geodetic monitoring of the bridge along Povitrianykh Syl Avenue recorded the vertical heights of the girders (B1–B8) between 132.82 m and 132.95 m, confirming the stability of the superstructure. We observed a smooth long slope of the bridge deck, with a consistent drop in vertical heights along the bridge axis from Support B (136.14 m) to Support A (133.79 m). We found structural deformations, including vertical displacement at the expansion joint of Support B (136.05–136.69 m) and local damage near Support A. These issues will help shape the reconstruction project. Investigations of the cross-sectional shape confirmed a single-slope or double-slope profile for the roadway slab. We found that, despite the difference in the vertical placement of the foundations (Support B is structurally lower than Support A), the top of the utility channel opening on both sides has a uniform height of 129.90 m, showing it is level.
