IL: new points to connect to nearby interchange.

[yakra]

I happened to notice the new IL I-57 318 point.

US45 & US52 could use a new point here to connect to it.
Unsure of proper nomenclature here. To the north, OSM has a "CH 9" tag on a road named "East 9000N Road", and the US routes have a CR9000 label. OTOH, IL50 has CR9.

On IL50, +X03 can be replaced with a point here. Should it be labeled CR6000? OSM has no "CH 6" tag here. *shrug*
To the north, CR9 may be better served by Division St?
