Drone video, various views, of the BNSF bridge over the Big Sioux River between Iowa and South Dakota on July 11, 2024. The bridge was initially heavily damaged during flooding on June 24, 2024.
Judging by the stuff piled up against the bridge, was this a flood damage. Water in flood can cause immense pressure…and then look like nothing when the floods have gone
It was caused by flooding. On June 23, 20224, the Big Sioux reached a new record level, over seven feet above the old record. The bridge is around 100 years old. BNSF sent a train across it around 6 pm when the water was only a foot or two below it and the bridge collapsed around 10:40 pm.
That plan to replace it. In an optimistic message after the collapse, BNSF said they should have it replaced by the end on the month of July. So far, engineers have been looking at it but nothing has been done.
