Duke87, I believe you mean VISIBLE_HIDDEN_COLOC. These can be marked FP, and sometimes there's legitimate reason to create them.
The most familiar example for most of us may be the former end of I-22, before I-269 was completed, with a hidden point on US78 IIRC.
There are places in Europe where a Tier 1 route transitions to a lower-tier route, at like a subregion boundary or maybe a major river or whatever, all freeway or expressway, no entrance or exit. An E Road concurrent with both routes will have a hidden point at the transition.
his will allow users browsing I-10 to click the link through to US90 and US98, but not vice versa.
IMO, the fact that the link cannot be followed from
both routes isn't necessarily a reason to not still allow it for one. I think it can be useful sometimes, and have done this a few places in Texas.
