Illinois literally has hundreds of more deserving projects than four-laning US 50. Yeah maybe if the state was flush with cash it might be worth possibly considering, but at this time it reeks of pork; and not the good kind; the shit that's mostly fat and gets sent to the cheap-ass dog food factory.
I think you can find plenty of projects that reeks of pork, especially in Illinois.
I also think there are projects that remediate some safety issues.
US-20 from Freeport to Dubuque is a huge one.
US-50 from Salem to Carlye uses a legacy (1920's era) ROW with poor geometry in places and inadequate widths. This is why this particular politician wants to see something.
I don't dispute US-50 doesn't show a need for a 4 lane completely across the state today, especially between I-57 in Salem east to US-45 in Flora. AADT shows very little traffic between Olney and Flora.
But the AADT does support a capacity increase west of Salem, which the representative was explaining in his comments.
The Lebanon Bypass is a safety issue all the way. Problems with heavy trucks in town and accidents.
If anything, US-50 needs to get off the rest of its legacy 2 lane ROW. Xenia to Salem, and then Salem to Carlye. The projects in the late 1960's didn't get finished and left some unsafe segments behind.
IDOT still thinks they can acquire traffic in the Twin Cities to St Louis route using the CKC and US-67 which is a fallacy. Once Missouri builds the Hannibal Bypass, shippers will have little use for the IDOT route.
Any US-67 enhancements at this point is to satisfy some political activities and 1 logistics center planned for Jerseyville.
Once frac oil comes back (and it will someday), SE Illinois will be a hot bed once again.
