Only noticed this due to an error message.
ny.i190;NY266;;;VISIBLE_HIDDEN_COLOC;ny.ny266@+x190(14B)
So, taking a look @ it, I wouldn't do any changes on I-190.
As for NY-266:
I-190/325 -> NY325
+x190(14B) -> I-190
Mainly due to how we've delt with other ramps intersecting @ numbered routes (like US-17 @ I-81 in VA).
