Interstate 180 North at Exit 14: IL 26 South - Hennepin / Lacon (Photo taken 8/14/19).

As Interstate 180 North begins, the speed limits are posted at 70 mph maximum and 45 mph minimum. These are the standard speed limits on most rural Interstate highways in Illinois. (Photo taken 8/14/19).

This overhead signage at mile marker 14 reaffirms the beginning of Interstate 180 North and the western terminus of IL 71. I-180 in Illinois is another 3-digit spur which does not follow Interstate standards regarding milepost and exit numbering. Therefore, the exit numbers and mileposts will increase in value even though I-180 is signed as northbound. (Photo taken 8/14/19).
