Illinois Route 267 is a north–south highway in the U.S. state of Illinois. It runs from U.S. Route 67 and Illinois Route 111 in Godfrey north to Illinois Route 104 and Business Interstate 72 (abbreviated BL 72) in Jacksonville. This is a distance of 59 miles (95 km). However, the state of Illinois' 2006 data shows the length of Illinois 267 as 39.46 miles (63.50 km), which is the distance from the Illinois 111/267 wye north to BL 72 at Illinois 104.
The routing of Illinois 267 over its lifetime is directly related to the routing of U.S. 67 since the 1950s. This is because U.S. 67 has been used at times over both the western route through Carrollton and Jerseyville, and the eastern route through Brighton and Greenfield, with various alternates to U.S. 67 being used on the other routing during these times.
The western route originally was U.S. 67 until 1950. It became Alternate U.S. 67 from the 1950s through 1965 as U.S. 67 was moved to the eastern route. In 1965, the western route was renamed from Alt U.S. 67 to Illinois Route 267. In 2001, the Illinois Department of Transportation (IDOT) finished construction of the Jacksonville bypass (a four-lane freeway around the western edge of Jacksonville, north of Murrayville). As part of this project, IDOT reverted U.S. 67 south of Jacksonville to its original, western routing.
The eastern route was established as U.S. 67 in the mid 1950s, and continued as U.S. 67 through 2001. It then became Illinois 267 in 2001. The southern terminus of Illinois 267 initially was in Medora at Illinois 111; between 2001 and 2006, it was extended south to reconnect to U.S. 67 in Godfrey, concurrent with Illinois 111.
Around 2006, IDOT completed the U.S. 67 bypass south of I-72. U.S. 67 was then moved onto this new segment, and Illinois 267 extended north from Murrayville to Business I-72 in Jacksonville.
