It seems to me that the only reason the 390 / 490 projects are being built is because the ISTHA is bored and needs something to do. the north 53 extension / 120 improvements are much more needed, but who knows what's going to happen with that.
On that note, I'm kind of wondering if there are any projects downstate that the ISTHA could be interested in taking over so that they can get built more quickly.

What all Downstate projects would have the traffic counts to warrant toll financed bonds? Unless Chicagoland Tolls are to subsidize Downstate Tollroads (thinking the West end of ISTHA's part of I-88 presently, or the whole state of PA being subsidized by the PA Turnpike Tolls)
The IL 336 Macomb to Peoria project I doubt would warrant toll financing.
US 20 to Dubuque from Rockford? I doubt it.
The I-474/I-180 connector Freeway north of Peoria along the IL River? I-39 isn't that far away as a Shunpike option.
US 51 continued upgrade to at least Divided Expressway, if not full Interstate 39 extension towards Salem/I-57? Depends how much time it would ultimately save between Salem and Bloomington/Normal, compared to the Shunpike/existing free route of I-57/I-74.
Otherwise, current Interstate corridors that might need expansion/rebuilding, might be more viable for tolling. But its a bit more of a chore to toll an existing free Interstate
I-57 from I-24 to I-64
I-70, I-80, I-55 across the state
My totally fictional one (which has been studied and didn't pass the test): Build I-24 Westward extension across Southern IL and Southeastern MO, and then link it up to the Avenue of the Saints in/near St Louis, to have a nice Twin Cities to Chattanooga corridor, and ISTHA can take the lead in IL and toll from Marion to the MS River crossing, wherever it would end up
One that I think might be viable for tolling, stays more in the greater Chicagoland area: Study with Indiana, the Illiana (mostly in IL) in combination with a US 30 Freeway upgrade in Indiana, connecting to the current US 30 Freeway in Ohio, and advance that as New/Future Interstate 80. I'm guessing that upgrade would have to be tolled anyway, depending on the Concession language of the Indiana Toll Road lease and free alternatives
Back to the original topic of the Elgin/O'Hare Tollway: How long will Google Maps take to show IL 390 east of I-290? And better yet, how long before Google Maps can use a 390 Route Marker instead of text-only reference to IL 390?
