Detonation of BNSF South Dakota side span over the Big Sioux River

Описание к видео Detonation of BNSF South Dakota side span over the Big Sioux River

Drone video on August 19, 2024, a planned explosion of the South Dakota side span of the damaged BNSF bridge over the Big Sioux River. My microphone was set up at the point of drone launch, which was about 1,100 feet from the point of detonation. About one second of audio was removed to synchronize the sound with the video, but the concussion set off a car alarm nearby. The One Minute Warning Siren can be heard at about 2 minutes 48 seconds.
