So ... um ... I've never seen a bridge survive a mountain falling onto it. Have you? Did they build the mountain too, or am I missing something else?
Honestly, a lot more of the bridge survived than I would have expected, and oh yeah, they saw this coming; It closed days before.
Well you'd generally do a fairly hefty geotechnical survey that would call this risk not and mitigate it.
I mean it could be a 1 in 100 year event. Feels unlikely that it would occur within months of opening though
Feels unlikely that it would happen within months(much more than that, since the start of construction) of a massive construction effort that involved forcefully and repeatedly vibrating large masses to settle and compact the road surfaces, adding tonnes of concrete, and letting heavy vehicles pass through at-speed on a slope that never saw such traffic before?
Ya don't say? By your logic, the regular inspections that caught the cracks would have been absolutely unnecessary.
How does my logic say inspections are unnecessary?
They generally base such things on the likelihood of finding issues in a given timeframe.
Pretending that's lower so soon after construction "if only it were built properly" is backwards and wrong. In-depth inspections are more common and necessary in the weeks, months, years closer to initial construction, and their findings identify issues that need checked as time goes on.
You don't check more often and thoroughly because you did a shit job at construction, in fact avoiding/faking inspections is one of the CHIEF hallmarks of shody work and corruption.
You see, that's when people die.
Cool, 100% agree

In addition to what has already been said by @Geoblock in this thread, your comment misses some important points here. They saw this coming as closed days before? - Well, yeah, the bridge was closed after cracks appeared on nearby slopes and roads, and shifts were seen in the terrain of the mountain ... How is this possible? What went wrong in the tests so that this bridge could be built at all?
They made a fuckup, caught it, and mitigated the risk to human life and well-being. A little work and some building materials wasted, but shit happens.
Read 'Cadillac desert'. Tell me how that happens, and still hasn't been addressed.
What went wrong, with an entire mountain you say?
