^Northbound trailblazer at Illinois 164, north of Kirkwood, August 2017.
Illinois Route 135 is a route in Warren County, Illinois, that just seems to randomly exist. Its route is shaped like an upside-down "L" (or like the capital Greek letter, gamma). This is off to the west of Galesburg and south of the Quad Cities.
Intersections will be listed from south, to north, to east.
The southern end of Illinois 135 is at Illinois 164 in western Warren County, north of Kirkwood:
Illinois 135 runs north, then, at Little York, Illinois 94 joins from the southwest to follow Illinois 135 farther northward:
Illinois 135 sort of trades longitudes with Illinois 94, and Illinois 94 continues north as Illinois 135 turns easterly:
The easterly movement continues as US Route 67 joins from the south...
