Figure 1 shows a collapsed beam bridge.
| Main span | ≅ 6 m |
| Girder | Precast concrete beam |
The bridge crosses a trapezoidal irrigation canal made of concrete.
Beam Bridge Collapse
Figure 2 shows the bridge.
The bridge entrance on shore 2 is on its original elevation level, while the bridge entrance on shore 1 is about one meter lower than its original elevation level. The girder, the deck, and the safety barriers are (visually) not affected by the collapse. Figure 3 shows a bottom view of the bridge on shore 1.
The foundation consists of a three-column bent with short columns and isolated footings. Figure 4 shows a schematic cross-section of the bridge before the collapse, while figure 5 shows the bridge's nearby upstream region on shore 1.
