At U.S. Route 24 (US 24), I-172 becomes Illinois Route 336 (IL 336), which runs north and east to Macomb via Carthage. The entire portion of I-172 and I-72 from I-172 east to Springfield is also known by its former name, the Central Illinois Expressway.[1] I-172 is Script error: No such module "convert". long.[2]
Route description
I-172 begins at a trumpet interchange with I-72/US 36, about Script error: No such module "convert". east of Hannibal before immediately entering Adams County while concurrent with IL 110 (Chicago–Kansas City Expressway). I-172 enters the Quincy area at exit 10 (IL 96), passing to the far east of the city. I-172 ends just northeast of Quincy, ending at US 24, continuing north as IL 110/IL 336.
History
I-172 originally was what I-72 is now from Springfield to the current interchange with I-172. This was approved by the American Association of State Highway and Transportation Officials (AASHTO) on June 9, 1991.
On April 23, 1995, after a reexamination by the Federal Highway Administration (FHWA), the highway to Hannibal was redesignated I-72, with the highway north to Quincy redesignated as I-172. The highway is non-chargeable, meaning that, even though it is an Interstate (designed and constructed to Interstate Highway standards and specifications), it was not built with federal funds.[3]
