On HN, we want curious conversation in which people are thoughtful and respectful toward each other. The idea is to collaborate in figuring out the truth together. I know it often seems like other people don't care about that, but a lot of this is an artifact of the medium, because internet comments lack the out-of-band signals that we normally rely on to evaluate other people's intentions.
Also, it's easy to perceive (and/or imagine) bad faith in others, and easy to underestimate the equivalent in oneself by 10x or more. Objects in the mirror are closer than they appear (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...).
If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.
Coincidentally, bridges have a 50-75 year lifespan. It's probably on the lower end in areas with tons of cold weather, salt and ice. Texas has less deteriorating weather in general. Hence the whole "northern cars turn to rust buckets" meme.
Also, this corresponds to Pittsburg's heyday being 50 years ago.
Pennslyvania's average age of a bridge is over 50 years old, where Texas lists only half of their bridges being over 40 years old.

So Pennslyvania's clearly got a problem, but Pittsburg (and the state on the whole) gets more rain and far more snow and ice, so even if they were the same age, it doesn't really seem comparable.
