It runs through the small towns of Brighton, Medora, Rockbridge and Greenfield.

Almost immediately northeast of the US 67 junction, they meet IL 255 at a diamond interchange.

Heading north of it and Greenfield, IL 267 meets Interstate 72 (I-72) and US 36 at a diamond interchange.

As part of this project, IDOT reverted U.S. 67 south of Jacksonville to its original, western routing.

U.S. 67 was then moved onto this new segment, and Illinois 267 extended north from Murrayville to Business I-72 in Jacksonville.
