Backfilling, Reinforcement, and Compaction

What happens here

With all culverts in position, the dozer begins the intensive process of backfilling. Fill dirt from the nearby pile is transported and carefully spread over and around the pipes, gradually building up the bridge's embankment. This involves multiple passes of pushing, spreading, and using the weight of the 35,000+ pound Caterpillar 953C Track Loader for compaction. Large stones are strategically placed within the fill layers to provide additional reinforcement and stability, locking the entire structure together and preventing erosion, particularly from the fast-moving water during floods.

Goal: Build a stable and erosion-resistant bridge structure.
