Corridor 88

Ultimate Interstate Corridor 880
Description Ultimate interstate 880 would replace the existing Interstate 88 designation allowing it to be assigned to the route travelling to the north through Dubuque IA and Rockford IL and also replacing the southern section of I-43. I-880 makes more sense since this route exists entirely within the state of Illinois and is basically an auxiliary route of I-80 anyway. Additionally the route number will make sense for those that are used to the existing I-88 route number.
Purpose and Need Releases the I-88 route number for use along the US-20 corridor. Route continuity
