The old Boone Bridge that crossed the Missouri River has finally been replaced. For decades this narrow and dangerous bridge served as one of the few connections between St. Louis and St. Charles Counties. This series of photos was pulled from a video of the complete explosion of the bridge. The second photo shows the explosive charges going off but the first photo shows a mysterious fire microseconds before the detonation. This is possibly caused by the extreme concussion caused by coordinated firing of the explosives. The third photo is of the trusses falling into the water.
