Linwood St, such a screwed up street... how in the hell did it wind up in 6 disconnected parts? But Guy St is even worse, it's in 9 parts

I'm guessing these were connected in the 1840s, but so many property owners changed things, sold parts, developers messed with things, etc etc and then newer major arterial streets and highways were constructed, that this was the result
