As I'm sure the OP knows .....
Got to give Chicago credit for creating perhaps the best street-grid and standardized numbering system with 8-blocks to a mile and each a 100 block North, South, East and West. Least is East as Lake Michigan is at its great Eastern boundary. Also standard alleyways behind each street.
In 1909 the city accepted a plan by Edward P. Brennan which unified the street numbering system naming the intersection of State and Madison as zero and numbering the blocks accordingly in each direction.
Now it is much easier to find your way without a map in the city of Chicago or even GPS.
Some links that explain what they chose for the evolving street-grid and then adopting the best options. As it too incorporated early suburbs in growing the city. They could some same names as others that were and their own addresses.
But the city had visionaries that said ---- "We can do this over better".
Decoding The Chicago Coordinates Grid System.

From link:
- in 1909, the City of Chicago decided to fight back against the growing menace of local residents continually getting lost and throwing temper tantrums.
- it created a completely new and foolproof address Chicago coordinates system.
- the address numbers increase or decrease depending on their distance in miles from the State and Madison axis lines where N S E W streets begin in the Loop.
- odd numbers are on the south and east sides of streets,
- even numbers are on the north and west sides of the streets.
- there are 800 addresses for each mile of streetscape
- eight blocks to each mile on the Chicago street grid.
- each block starts the next multiple of 100.
- on the north and west sides, the “primary" streets run a mile apart,
- with the “secondary” streets run halfway between the primary streets.
There are a few exceptions to this otherwise logical street numbering system. Most notably a 3 mile segment of Archer Avenue, a diagonal street on Chicago's southwest side.
Chicago also added diagonal streets to its grid .... running diagonally through Chicago's grid system on all or part of their courses. These streets tend to form major 5 or 6-way intersections. In many cases they were Indian trails, or were among the earliest streets established in the city. Diagonals are numbered as north-south or east-west streets too.
The density of main streets in downtown Chicago -- is greater than in the rest of the city, with some at half-block spacing (just 50 address numbers or one-sixteenth mile from the next parallel street), or block spacing between main streets, unlike the rest of the city where the main streets are spaced at half-mile and mile intervals.
Many of Chicago's suburbs use the same numbering system as Chicago, while other suburbs use their own systems.
One diagonal street here shoots from the core
and also goes by Wrigley Field off the picture though.
