It's sad, but it looks like in the future, only the Belvidere and Dekalb Oasis will remain.
Since when are the plans to remove the Lake Forest and Lincoln Oases?
My apologies, I shouldn't have been so definitive. I should have said the Belvidere and DeKalb Oasis
might be the only ones to remain in the future.
The reason I say that is because I wouldn't be surprised if at some point, the Tollway would want to redo the rest of the system (in the suburbs, that is) to incorporate the wider shoulders and active traffic management that they've done on I-90 and will do on the Central Tri-State. Granted, I doubt they go back and widen those sections for at least 15-20 years at the soonest, but any future improvements to the north and south Tri-State will require the removal of the Lake Forest and Lincoln Oases.
I think the south section (the I-80/294 duplex) will likely need five lanes in ten years (especially since the Illiana is likely dead), and they'll need to redo it anyway since ISTHA didn't rebuild the crossroad bridges to eliminate the "pinch-points" (I guess that is the new Tollway term for the crossroad bridges that were not reconstructed when the road was widened, and have narrow shoulders underneath).
In other news, it looks like the Tollway will be replacing the Bradley Road overpass on the North Tri-State just north of the Lake Forest Oasis next year (it is on their bidding schedule). I wonder if they'll bring the shoulders up to regular standard when they do so.
