Just taking a random look at the route, and noticed a few possible issues that should be addressed.
(Going West -> East)
1. I think there should be a point @ CR34 just to the East of GalRd. Why? Because it's a direct connection down to I-90 Exit #52. While I couldn't find a mention of I-90 at that intersection, I think it's well within reasonable range to add the point.
2. Recommend a point at Beverly Road between 'IL25' & 'IL59'. Why? Direct connection down to I-90 Exit 58.
3. TouAve_E needs a recenter.
4. I-90 -> I-90(76)
5. DevAve -> I-90 -- Also, this needs to be synced with I-90 for a graph connection. If you want to keep the DevAve label, I guess that could work, but we do need the graph connection here for I-90.
6. We need a point for either North Canfield Avenue, or I-90(80) (no graph connection here). Reason is because IL-72 is only on the northern side road of I-90 here. If you want to use the I-90 ramp, recommend here:

7. Need a separate point for I-90(81A). Recommend here:
I-90(81A) http://www.openstreetmap.org/?lat=41.981925&lon=-87.810518
8. IL-72 shouldn't have a graph connection here with I-90. It should only have a graph connection with IL-43. So, I recommend the following changes below. Thankfully, no changes here to I-90 will be necessary. Only changes to IL-72 & IL-43 needed.
IL-72:
IL43 http://www.openstreetmap.org/?lat=41.981087&lon=-87.806962
IL-43:
IL72 http://www.openstreetmap.org/?lat=41.981087&lon=-87.806962
No changes to the I-90 point on IL-43 will be needed.
