Thankfully nobody was hurt. I am not an engineer, but I would have expected to see a concrete base below each set of support pilings.
The prior bridge lasted 50 years, this didn’t last 50 days. The folks interviewed seem might calm about the whole thing.
There is a bridge I drive over every day. It was built maybe 12-15 years ago on a Turnpike. They misjudged the piling sink by about 8 inches and it’s like a series of Motocross Whoop-Dee-Doo’s up and down up and down. They call it the rollercoaster highway.
