I have read about this in our engineering news reports.
This is how I understand the problem. There are 36" diameter pins that hold the bridge together but allow movement in case of earthquake. The pins have been failing at a high rate during installation. Workers pounding them in have fractured them! For a while nobody wanted to admit there was a problem, so assembly continued with a new pin whenever one broke. Finally, after someone said "hold on, there are way too many flawed pins and we need to pull ALL of them to check them", they decided to take action. Unfortunately, by now they had poured concrete over the top of the pins and now the concrete had to be removed!
Sometimes real life is funnier than something you can make up!
