Ep 130 Mini Failure 44 Bay Bridge Hydrogen Embrittlement Failure

We’re releasing episodes from our mini failure library while we’re on production hiatus.

This week’s Mini Failure is about the hydrogen embrittlement failure of the Bay Bridge between San Francisco and Oakland. Almost 100 rods were at risk of failure, after a construction delay and lack of protection subjected the rods to standing water and weakened them to the point that a third failed.

Original Air Date: June 11, 2023
