@amazeifystore: This design flaw caused a total bridge collapse. 🌉 The Schoharie Creek Bridge failure in 1987 wasn't just about the flood. Designers used riprap armor, but the pier sat on erodible soil instead of bedrock. The water literally tunneled right under the footing. 🌊 Surface protection is useless if the ground itself washes away. Would you trust armor you can't see?
