Control city on one interstate but not on another?

Inspired by my reply to this comment in one of the control city threads...

I always found it interesting that Illinois uses Memphis as a control city for I-57 at the junctions with I-94 and I-80 in Chicagoland, especially since I-57 doesn't go within 100 miles of Memphis.  Granted, I-57 is the primary route you would take to get from Chicago to Memphis but still . . .

Sikeston would be a logical control, because it's a major interstate junction and the (current) terminus of I-57. But you'd probably end up with Sikeston being signed on I-57 and Memphis being signed on I-55.

Thread idea...

How many interstates have intersections where the control city is listed on one of the interstates, but not the other?

Best example I can think of is I-77 and I-81. They intersect at Wytheville and have the infamous wrong-way concurrency, yet Wytheville is listed only as a control city on I-77. It's not used for I-81 (Bristol and Roanoke are).


Government would be tolerable if not for politicians and bureaucrats.

An easy one to cherry pick right off the top...

Syracuse, NY is used on I-81, but not on I-90.

For many years Dayton was used on I-75 but not I-70 that has been changing recently. Bloomington/Normal is used for I-39 but not I-55 or 74. Lexington Va is used for I-64 but not I-81.

- Evansville is used on I-69 and not used on I-64 (which uses St Louis/Louisville at that point).
- Lodi is used on I-76 and not used on I-71 (which uses Columbus/Cleveland).
- Mercer is used on I-80 and not used on I-79 (which uses Pittsburgh/Erie).
- Wentzville used to be an I-64 only control city, until recently installed APL pullthroughs on I-70 WB in St Charles County uses it.

Bloomington or Bloomington/Normal are absolutely Controls on I-55 and I-74 in Central Illinois, but only as Secondary Control status, as the Primaries are Chicago and St Louis/55 and Peoria and Indianapolis/74

IDOT uses Evansville IN as a Secondary Control for I-64 EB between Mt Vernon and the Wabash River. I don't think InDOT uses Evansville at all for 64

And I really don't understand why that changed. I've driven the stretch of I-70 between St. Louis and Columbus numerous times - I know that while it goes through the Dayton metro area, it barely brushes up against the north edge of the city itself. I think between Indianapolis and Columbus, in my opinion, Dayton should be a secondary control city at most, with Indy and Columbus being the primaries.

Imo requiring an interstate to go through city limits just to be able to use it as a  control city seems very restrictive. Metro area is enough.

Ohio doesn't use secondaries on interstates.

I thought about that one but I-64 stays quite to the north of Evansville so I am not sure if that one counts. I just thought of another one that is relatively new. I-165 uses Bowling Green while I-65 does not.
