I honestly don't think any further upgrades are needed between Macomb and Jacksonville, nor between Manchester and Jerseyville. At this point, I'd simply four lane the Macomb bypass and tie it directly into US 67, then call it a day on US 67/IL-336 upgrades in Western Illinois.
I tend to agree.
Finish 4 lane US-67 to Jerseyville for the logistics park.
Finish 4 lane CKC update of Macomb Bypass from Super 2.
I think some of the dough got pushed over to the West Springfield freeway work.
With most of the CKC (IL-110) work done for now, I think Western Illinois has gotten a pretty good chunk of highway dollars the past 30 years and needs to reassess their traffic patterns.
It's the bridges on the Illinois River that sorely need work. There is one still sharing a draw bridge with BNSF railroad. A railroad employee operates the tollbooth!
