IN28:
* I believe IN3_N should be US35_S (or US35/3 or US35/3_S, depending on the rules).
IN62:
* All of the points from 118(64) to 10(265) don't match the format of the other state road/interstate concurrencies. Additionally, I-64/264 is mislabeled (should be 64/265).
* Did IN62 move onto I-265 recently? Or is it an extension of I-265? My old route notes show that I got on IN62 at US31 (which no longer has access).
IN120:
* I believe IN15_E should be IN15_N.
IN126:
* Is this gone?
IN157:
* I believe IN67_S and IN67_N should also include US 231.
IN203:
* Lovely. There's IN356_W, IN356_E, IN3/56, IN3_S, and IN56_W. I have to congratulate INDOT for making things difficult for us.

IN252:
* IN31_N and IN31_S should be US31.
IN329:
* Decommissioned?
IN345:
* Ditto?
IN431:
* This too?
IN526:
* The last time I was in West Lafayette, I remember signs for this. But is it no longer?
