Bridges are still functional with giant holes blown in the deck. Maybe capacity is reduced, or it needs patchwork, but still functional.
That is why they’re typically targeted with large bombs, or missiles. Even then, might take a while.
If this wasn’t a hot war, it’s possible a covert demolition team could rig enough explosives at the right structural points, but trying that now is a great way to lose a bunch a SOF teams.
Here’s a somewhat relevant parable about how hard it can be to destroy a bridge during war.
News, tech, left-wing politics, memes, anime, and porn are Lemmy’s biggest community types.
I know a lot of different subtopics fit under each, and I’m sure I left a few top level subjects out, but my point is that there are a lot of mid-sized, and especially smaller (by Reddit standards), subreddits that Lemmy is no where near being remotely useful as a replacement for yet.
I have community subreddit collections that I don’t see Lemmy replacing anytime soon. I mean, I hope they do. I still check every so often, and yes, communities for them exist and they have maybe a few dozen users, but not enough to even try to just suck it up and deal.
