Routing Help WO to CO

[Grumpy Goat]

It's winter, and time to plan next summers travel. I'm looking to go south from Rock Springs, Wyoming into Colorado. Google maps is suggesting route 430/10N/318 will get me down to route 40. I'm a little suspicious on this. Can anyone advise if this is all paved roads?

Thanks for any help.

ps: I've done the route 191 down to Vernal before, and am looking for something new. But if this is the best way, I need to consider it.

Looking at the Google map I got, the route you mentioned (blue) appears to be the fastest. Using Google Street View it appears to be paved, although I am not sure about Co Rd 10N, which appears to be a hard-packed gravel road for 22 miles according to the 2008 image data. This web page from Oct 2015 says "430, though, turns into Moffat County Colorado Route 10N, which is a pretty fun and scenic dirt road". Could be paved since then but with other options and riding an RS, you might want to give this a pass.

   

On the other hand, the route through Vernal to Grand Junction appears to be paved all the way.
