List of unused highways in Illinois

An unused highway may reference a highway or highway ramp that was partially or fully constructed but was unused or later closed. An unused ramp can be referred to as a stub ramp, stub street, stub-out, or simply stub. The following is a list:

Illinois

Chicago

• Downtown, the ramps onto northbound and southbound Interstate 90/Interstate 94 (Kennedy Expressway) from Washington Boulevard were disconnected, leaving stubs descending onto the expressway. 19 The same was done to the Monroe Street ramps. 20

Peoria

• East of Interstate 474 at the New Farmington Road/Maxwell Connector interchange, stubs exist on the mainline. The expressway west of the interstate is slated to eventually carry Illinois State Route 336. However, the only part finished is a short stretch connecting I-474 with Maxwell Road to the west. The freeway continues past the completed ramps to I-474, but is closed and just dies in the grass. The Illinois Department Of Transportation does not have the road continuing east of I-474 as of right now. 21

• There used to be a ramp taking west-bound traffic off the McClugage Bridge and to northbound Illinois State Route 29. This ramp was removed prior to 1998. However, the bridge still has part of the ramp attached (Webcam, click on 'Western Ramp' or here on the left side of the picture). The old configuration was a unique diamond interchange 22, while the new design has a new loop ramp. 23

Mossville

• At the northern end of Illinois State Route 6 (an extension of Interstate 474), there is an interchange in which all northbound traffic is diverted to Illinois State Route 29 and the freeway begins for traffic going southbound. Currently, the main traffic lanes extend north past The Intersection and a southbound-to-eastbound exit exists (but does not connect to the mainline, yet 24). All ramps leading to and from the traffic lanes north of the intersection are present, though the westbound-to-northbound ramp does not yet connect, either. There are plans to extend Illinois Route 6 north beyond Chillicothe to Interstate 180 as Illinois Route 29. 25

Decatur

• There are stubs and grading in the median of Interstate 72 northwest of the city for a planned but never built connection with Interstate 39. There is also grading north of this proposed interchange where crops are no longer planted. 26

East St. Louis

• As a result of decommissioning U.S. Route 460, there are stubs at the end of the Tudor Avenue exit from Interstate 70/64/55. 27

Rockford

• The Wallenberg Expressway (originally known as the Woodruff Expressway) was designed in the 1970s to go northward at the interchage of Interstate 39 and U.S. Route 20 into downtown Rockford. The highway would have been built northwest along Woodruff Avenue in Rockford but was axed due to community opposition. As a result of the road being cancelled, a short stub exists where the mainline would be coming from the north. 28 North of the stub, grading exists for the road, as well as a cloverleaf ramp that was to go to northbound I-39 and eastbound U.S. 20 and a ramp to westbound U.S. 20. The only part of the road build is now a ramp from I-39 to westbound U.S. 20. The ramp has an extra wide shoulder, the result of combining the former mainline and the ramp, and grading for a cloverleaf ramp from eastbound U.S. 20 to the road that was to go north also exists. 29
