The Silver Bridge Collapse Explained

I'm curious how this bridge collapsed. It should have been perfectly safe, but there was

one tiny flaw in a single metal bar that caused a massive destruction during

rush hour traffic. Unlike modern suspension bridges with thousands of safety wires, the Silver Bridge's

entire strength relied on just two massive metal chains called eye bars. This innovative design

had a fatal flaw with zero safety measures. If a single link in either

chain failed, the entire structure would collapse. The culprit was a

slow and silent process called stress corrosion, cracking for over 40 years.

The constant pulling force on the steel, combined with moisture trapped deep inside
