Here's more detail about the proposed transit expansion on the west side and western suburbs. The article is from the
Wednesday's Journal, the local Oak Park paper.
Blue Line extension gathers steam
There's a nice diagram showing:
1. Blue line extension.
2. "J-line" bus corridor linking Schaumburg to Naperville, looks like it follows I-355.
3. Intercircumferential Rail line connecting Ohare to Midway (using ROW near 25th Ave)
4. Midcity transit way, bus transit along Cicero from Jeff Park to Midway (bus? This had better use the rail ROW east of Cicero.)
