The old Highway 47 Bridge came tumbling down after hundreds of explosives were set off. The old Route 47 Missouri bridge was an iconic part of the community in Washington but on Thursday it came to an impressive ending. The bridge opened in 1936. It was 83 years old when it fell into the Missouri River. The impressive implosion that brought everything to a stand still also brought river traffic to a stand still. Crews will work throughout the evening with weather permitting, and anticipate having this portion of the river open for barge traffic on Friday.
