I have thought about it for hours by now, and read literature on the matter. It is definitely possible to build berms that protects a bridge from catastrophic failure in case of a ship collision, and it is widely done during modern bridge construction. Please be less sure of yourself when you clearly don't have any actual knowledge on the subject.
- btbuildem 3y agoI'd love to see a few examples, since you're so versed on the subject. I'm not a civil engineer by any means, but I imagine the people who designed and built that bridge knew what they were doing. There are likely limitations imposed by the site bathymetry and other things we don't know about. You can get a good look at the aftermath here: https://www.youtube.com/watch?v=WssFXRzRVLU https://www.youtube.com/watch?v=WssFXRzRVLU I'll be interesting to see how they choose to rebuild it.
- KoftaBob 3y agoThere are real world examples of what it would look like, they're called "dolphins": https://en.wikipedia.org/wiki/Dolphin_(structure)#/media/Fil https://en.wikipedia.org/wiki/Dolphin_(structure)#/media/Fil... "The new bridge is protected by 36 dolphins: four large dolphins protecting the two main pylons supporting the cable-stayed main span plus 32 smaller dolphins protecting bridge piers for 1⁄4 mi (1⁄2 km) to either side of the main span"

- low_common 3y ago"I have thought about it for hours by now, and read literature on the matter." Ah, the classic, pompous Hacker News user. The Baltimore Port Authority should've hired you to prevent this disaster - you're a genius!
- pgwhalen 3y agoSeriously, this comment has to be satire.
