St. Clair County (IL) Highways
Note: The county highway numbering system changed in 1996 when the county phrased out letter-appended routes. However, most of the signs on the roads have the old numbers on them -- and that may remain that way for the unseen future. Some new numbers are not known at the time, and the county has refused to provide me an official route list.
The new number is the left column, the road name(s) and in the next column, followed by old number(s), and the notes regarding to the road. The old system had a lot hidden multiplexing with county and state-maintained roads, the new system pretty much eliminates that. Some county highways are merely subdivision streets. If you got any info about these routes, email me.
