That's fair. I do also agree that it seems obvious, but given the number of the people in this thread and elsewhere suggesting that fixing it would just simply be so easy, it doesn't seem like that's the case for many others.

I didn't read the OP as saying "nowhere else has infrastructure problems" but "bridges are a particularly acute problem in Pittsburgh for these reasons." I would certainly agree that suggesting this kind of issue is unique to Pittsburgh would be misguided.
