This is sadly going to be another case where a nice upgrade by the Tollway is overshadowed by IDOT's lack of upgrades or half hazard job of doing one (see I-88 inbound at the Hillside strangler). I-90 at I-290 in Schaumburg will be another. The newer interchanges the Tollway has generally done a good job of at least keeping the mess off their portion (essentially, showing exactly where the burden of upgrades remains with IDOT). This includes I-355 at I-55 or I-355 at I-80 (which actually forced IDOT to finally widen I-80 in this area).
I wonder what would need to be done in the future when (not if, because it will need to happen someday) the I-290/IL-53 system interchange is finally addressed. It does not seem like the work on I-90 was designed to accommodate future improvements to the interchange, which you would have thought they'd at least done so the construction is minimally disruptive in the future.
However, I don't think they will do exactly what was planned in this document (https://www.illinoistollway.com/documents/20184/96652/2007-10-31-I-90-LAMP-EXEC-SUMMARY.pdf/ec1183d3-55f4-4db0-9998-7d64e8fe8ca7?version=1.0) simply because it would require too much ROW. Though I wonder if they could shift the interchange slightly east?
Some thoughts on this proposed interchange against what would or could be done now:
1. The loop ramp in the NE corner would almost certainly not be built or feasible now since Meacham is only accessible from traffic on WB I-90 solely. This would allow for the ramp from WB I-90 to NB IL 53 to be straightened and to do something about the very short merge in that direction.
2. Instead of a loop from WB I-90 to SB IL 53, why not just make that a flyover (they seem to have the space needed to do it)? This eliminates the ROW issue in the NW corner of the interchange, and the only property that might be taken is the Joe's Crab Shack.
3. I actually think the work on I-90 itself does provide for some accommodation. The merges onto I-90 are definitely longer, and I feel the ramp from EB I-90 especially has a longer deceleration area (probably so the Woodfield traffic doesn't back up onto the mainline as easily as it used to). Agreed, though, it would take some work that could impact mainline I-90 traffic at the interchange.
4. I would hope IDOT would do more to address some of the IL 53 congestion issues just North of this interchange as well. That merge from the six lanes (three express, three local) down to three in such a short period is bad news each rush hour evening.
