> Just in time edit: It was pointed that I forgot one of the most important things: the numbering system encodes distance as well. Every 100 on the grid, or one full block, is 1/8 of a mile.
Except for the first three miles south of Madison St., which are 1200 S (Roosevelt Rd.), 2200 S (Cermak Rd.), and 3100 S (31st St.) - which also gives the numbered streets southward their pattern of having each mile being an odd number (63rd, 71st, 79th, 87th, 95th, 103rd, 111th...).
The Chicago grid extends far beyond the city as well, with many suburbs using it. Will County also uses it for unincorporated areas, so it extends to 37500 South in Reed-Custer Township. There are still many suburbs that prefer to roll their own grids, though, and at least one (Harvey) that uses its own numbering on east/west streets and Chicago numbering on north/south.
- Kon-Peki 4y agoNorth Ave and Roosevelt Rd, as named, extend all the way west from the lake to the Kane County line. But the roads themselves go all the way to Ogle County - 2/3 of the way to Iowa. North Ave ends at a T-junction in the middle of corn fields, while Roosevelt ends kind of unceremoniously at a messed up intersection at a baseball field in Rochelle.
