It won't affect anyone's travels either way. It's purely housekeeping.
As I see it the arguments in favor of a move are:
- The road is not maintained by the state of Colorado, rather by a multi-county agency. This could be interpreted as making the road a county route.
- While CDOT does have an internal numerical designation for the road, it is 470B, not E470
- The road is not signed with CO state highway shields. It has its own special shield.
- It is an odd case with few if any direct parallels, but the most similar situation is Clark County 215 in Nevada, which was put in usasf.
And the arguments against are:
- So what if it's county maintained, there are plenty of state routes out there that are county maintained in part or entirety. And it has a state route designation!
- So what if the internal designation is slightly different, there are plenty of cases where the internal designation for a road has a suffix that isn't signed in the field. See all state routes in Maryland with multiple segments for example.
- It is contiguous with CO 470, which is clearly a state highway by the same number. And it exists due to planning by the state, even if the state didn't build and doesn't maintain it.
- When in doubt, default to status quo. Ruling on the field stands unless there is clear and convincing evidence it should be overturned.
It makes no difference to me personally. I have no objection to moving it. I have no objection to leaving it as is, either.
It would be nice if we had an actual E470 shield for it though, instead of shoving "E470" in the CO shield which just doesn't look right.
