- There is not any signage for ID 13 Business in Kooskia, so this route should be deleted
- There is not any signage for ID 128 Spur in Clarkston, so this also should be deleted and... really, 1PPI with US12 should apply here anyway I'd argue. In either case, the east end of ID 128 has a coord mismatch with the corresponding point on US12.
- As currently signed, ID 64's eastern terminus is at ID 162 (5th and Pine in Kamiah). It does not run concurrent with ID 162 to US 12. Note that this has changed since GMSV was there in 2008.
- Exit numbers 438 and 449 on US 95 are posted in the field so these points should be relabeled accordingly
- On ID200, the point US95 would more aptly be labeled US2/95
