We have this in almost every city in Australia, too. Sure, some of them are dumb (looking at you, Cahill Expressway in Sydney and Clem Jones Tunnel in Brisbane) and probably shouldn't have been built, but nonetheless, that is... Normal? And generally not seen as "rayciss" here, yet, thank guff...

I'm sure we will import the same race-baiting nonsense in a couple of years, though. We usually copy you guys, just a couple of years behind...

In general, the shitty, race-divided parts of the cities in Aus are generally the equivalent of "Skid Row" in LA - i.e. a few small suburbs near the city centre, full of poor, drugged-up Abos and the occasional "migrant", where you generally shouldn't go alone at night (notably, Redfern in Sydney, West End in Brisbane, Footscray, Fitzroy and North/West Melbourne, and, the worst I have personally seen, due to the higher Abo population, Northbridge in Perth)...

So in that sense, those problems carry over, here, too. Northbridge and three of those Melbourne suburbs are heavily impacted by freeways and train lines, too, so I guess that could be argued to be a thing here as well, if to a lesser extent.

Sydney usually gets the worst rep for this sort of thing, but honestly, Perth is the Australian city where highway planners seemed to most closely follow the model of "cut the CBD off from its suburbs", followed by Brisbane and maybe Adelaide. It's just that Sydney and Melbourne like to pretend that the rest of the country don't exist, most of the time, lol.
