O really does go up to Market.
Warren Barrett Drive is the big thoroughfare.
For the neighborhood southeast of Warren Barrett and Laidlaw, there are three north-south streets: Lindell (stub), Vermont, and Arch. The cross street is Bates. There are also two *alleys*, between Lindell-Vermont and Vermont-Arch.
At the tracks, I think Hannibal considers Lindell to be the north-south section *and* the short east-west section that connects it to Warren Barrett.
