I wish this map weighted streets for density. Seattle is mostly NSEW as portrayed in the plot, but the downtown core famously has two competing grid systems.
Yeah, I think it’s something you see in any city built in the last several hundred years that’s near water and engaged it maritime transport. Recent enough that we discovered that the grid system makes sense and simplifies things, and near water which gives one rational orientation for the grid, coast aligned centered around the port, ripe to conflict with the other “north south” sensible alignment.
If you look at Detroits roads, it’s got three grids, one north-south, one aligned to one part of the coast, and another smaller one aligned to a different part of the coast. It’s also fun because you can still see the faint remnants of when the roads were a radial spoke system built around the original french fort that caused the city.
Manhattan never gets far enough from the coast to switch.
It makes me wonder about cities with notable rivers built after the grid system. Do they align to the river, or just build bridges and pretend it’s not there?
Here’s one that includes more cities around the world
