Thanks because after years of no news Illinois is going to have some. What is not clear but the politics is radically changed.All but 67 are stale then because nothing has been done in a decade on most.US 50 does have an EA going on from Olney to Indiana another 4 lane ROW at each since 2012.
Yes, there is a US50 Coalition pushing for a 4 lane from O'Fallon to Vincennes.
The 4 lane in Illinois west of the Wabash ends north of Lawrenceville today, is a Super 2 briefly, before heading down an alignment to Olney. In the original Interstate Plan, this route was supposed to be the St Louis-Louisville route but was moved south (now I-64). The EA is to raise the road from the Wabash River to the Walmart Distro Center west of Olney to interstate standards. That distro center supports SE Illinois and parts of western Indiana so truck traffic has been increasing.
That US50 section around Vincennes and Lawrenceville was bulit in 1961-1962, but the road is in decrepit condition. Also the economics in the region have changed dramatically since that road was built. That part of the state used to be a large oil producer (Lawrenceville used to have a large refinery) and the road also served a former USAAF base, which for awhile was an international airport. There are no more commercial flights into that airport either.
Essentially, US50 would have a full interchange with IL-130 and a simple on/off ramps at IL-250 north of Bridgeport and at Red Hill State Park. They would convert the Super-2 west of Lawrenceville and reconstruct the full interchange and bridges at IL-1. I doubt any ramps will exist for the airport which is general aviation now since the runways were truncated back in the 1980's. The ramps for IL-33 and the US50 BUSN Loop for Lawrenceville will remain.
Unfortunately IDOT has allowed a large amount of property creep along the ROW east of Olney since the current route was built in 1961. Olney has plans for a large industrial park where US50, IL-250 and the CSX railroad meet at Holly Road, but CSX wanted Olney to pay for the switch and new rail spur. With CSX having closed that line between O'Fallon and Flora, Olney only is served from the east now by rail, making a large industrial park a challenge. Olney let a federal grant lapse to reimburse them for CSX because they found they couldn't afford to extend city water and sewer. Since Illinois was broke, they couldn't help either.
So now they are hoping a US50 4 lane extension will help them attract new industrial clients.
The area was a target for oil fracking, but when Illinois passed the most onerous fracking rules in the world, many of the frackers have moved on. If oil prices ever go back up, I can see this highway getting used heavily for oil support. Until then, it will mostly be used for regional purposes, like agricultural, small industrial, and local A to B traffic.
