@amazeifystore: A bridge can fail at the connection, not the beams. In the 2007 I-35W collapse, undersized gusset plates at key joints had roughly half the required capacity. Added weight and construction materials increased the demand, and the NTSB found the plates initiated the collapse. A sobering lesson in engineering: what holds a structure together matters just as much as what it’s made of.
