My bad. I knew there was a segment down there that, when originally entering my mileage, didn't seem accurate based on my recollection, but I thought the Victor segment was the whole area south of US24 (without looking to verify). Yes, I think you can merge those two. Having clinched the whole thing, there is definitely a Sedalia section, then it goes to dirt and turns into a county road, then the Woodland Park section which goes all the way down to Victor, stops at Phantom Canyon Road (or nearby) goes to dirt all the way to US50 and then a Florence section.
CO128 can me merged too. When I drove it a couple months ago, I didn't notice anything to indicate that it stopped and I drove it from end to end in one drive.
The other discontinuous in Colorado:
CO7 - I'd be in favor of merging the two segments. Unless I'm missing it, I don't see any "End 7" signs, and the "To" signage isn't any different to CO14's weirdness in Fort Collins.
CO15 - Keep separate as the two are connected by dirt roads.
CO40 - I think you can get rid of the Limon segment. I don't remember seeing, nor see on 2009 Street View, any signage.
CO60 - I'd be in favor of merging. There is a directional sign to Campion coming from the East pointing you down the frontage road which connects the two segments. The sign from I-25 for CO60 lists Campion as its control city, so I feel like CODOT is trying to make it continuous even though there aren't any reassurance markers there. There are no end signs that I remember, just a complete lack of signage for when you have to go under an I-25 overpass from the frontage road. I missed the turn originally and had to double back. While to some that might mean keep them separate, for me separate means either an end sign or a distinct change in road type. Crappy signage alone doesn't qualify it.
CO90 - Haven't driven yet, but there is an end sign, so keep them separate.
CO105 - End signs. Keep separate.
