The load-bearing structures of the existing bridge were rebuilt, increasing the external dimensions of the structure – its length and width.

The existing bridge structures were completely dismantled and replaced with new monolithic reinforced concrete structures, forming a frame-type bridge structure. The supports were concreted on installed shallow foundations.

At both ends of the bridge, precast reinforced concrete transition slabs were installed.

Protective barriers were installed on both sides of the bridge on top of the reinforced concrete barrier blocks.

At the approaches, embankment cones were formed with slopes of 1:1.50, which were then smoothly connected to the road embankment slopes beyond the bridge.

Water drainage is ensured by directing water through slopes into collection wells installed at the ends of the bridge. From these wells, water is discharged via pipes and channels into the canal. The canal bed was reinforced with dumped field stones.

Additionally, 30 m of road before the bridge and 40 m after the bridge were reconstructed, an access road to a private land plot was installed, and road markings were completed.
