Heck, traffic reports on AM 780 and AM 720 already refer to the corridor as the "355/53 combo" or something along those lines. Unify it.
And go ahead and add St Louis, or at least West Suburbs, as the Southbound/Eastbound Control for I-290 at I-90. I believe going Outbound/Westbound on I-90, the Southbound/Eastbound Control for I-290 already is West Suburbs, but heading Inbound/Eastbound on I-90, pretty sure the 290 Control is Chicago, whereas the 90 Control is Chicago - O'Hare, unless the signage changed with the 90 rebuild. I no longer live in the area, so haven't driven that way in a few years.
IDOT did give 355 Northbound @ I-80 the Control of Rockford -- IDOT sees, at some level, the 355/290/53 corridor as one route
In general, I don't like the (Directional) Suburbs as Controls, but I guess that ship has sailed. Already appears way too many times for I-290, I-88, and I-355. Why larger suburbs like Schaumburg, Aurora, and Joliet, and possibly Bolingbrook and New Lenox, can't be suburban Controls, I will never understand. Aurora and Joliet are used sometimes as Controls already
