CO: US6 concurrency with I-70 possibly wrong

[Spinoza]

Hi, I see that US6 in Colorado, between waypoints I-70(169) and I-70(171), east of Eagle-Vail, has been set to concurrency with I-70. I drove there some months ago and I remember US6 to run parallel to it, until it becomes US24 leading to Minturn and ultimately Leadville. Google Maps and Openstreetmaps seem to agree on that.

There isn't a concurrency there; I've clinched that part of I-70 (just have I-70 in my list file) and the concurrency checker didn't autoclinch that segment of US 6.

If that makes any sense.

The US6 point for I-70 exit 169 is slightly off to deliberately break the concurrency (http://www.openstreetmap.org/?lat=39.622648&lon=-106.484428 rather than I-70's http://www.openstreetmap.org/?lat=39.622648&lon=-106.484427). It's hard to tell on mapview though, especially if (like you have) you've clinched both (you can just about see the difference between I-70 and US6 concurrent, and I-70 and US6 not concurrent on the_spui_ninja's)

the_spui_ninja hasn't clinched 169-171 on US6, but has on I-70.

Ok, I see now. Sorry for bothering.

Maybe the two roads could be drawn more distant in that segment, for instance with curves? It's really hard to tell them apart just by looking at the map.

Thanks for clearing this up.

I'd say that's a spot where shape points would clear up the ambiguity.

It's no bother.

Done.

You'll still have situations where two routes share exactly the same centerline, but are not concurrent. Like I-65  and US 31 in Indiana just north of Louisville KY (I-65 is the mainline, US 31 is on the frontage roads) or Interstate H-1 and HI 92 passing the airport (H-1 is on the upper level, HI 92 is on ground leve).

Thanks, much better now.
