Alright, well, I'm in Boston. The military is responsible for maintaining the walls in quarantined cities, as well as... well, pretty much everything. They're the only government left, so they run the place. It's the same in most cities, as far as I know. But Pittsburgh, now Pittsburgh is different –– the military got driven out five years ago, and the people took the city back for themselves. Haven't heard anything for a while, but maybe they're still going, maybe not. They might have been entirely overrun by infection.
