Tucson to Olympia, WA

Thanks for the suggestions.

To answer azdrheat's question; unfortunately I have to go through CA going to Tucson. A very close friend's husband was diagnosed with brain cancer. I'll be making what will probably be the last visit to see them in Sacramento. Then I'll be going on to Las Vegas, Phoenix, and Tucson.

Watch the weather. Odds are against snow, but not by a lot.

Make almost this same trip twice a year. Tucson to Phoenix, west on I-10 to Quartzite, north on 95 to Las Vegas. Continue north on 95 to Reno, then Hwy 395 towards Susanville. CA. You are in California for a very short period of time and distance and no traffic to speak of. Head north again just prior to Susanville and head towards Oregon on Hwy. 139. North from Klamath Falls, OR to central Washington or cut over to I-5 on Hwy. 58, or alternatives Hwy. 26, Hwy. 84 etc. All good roads and little or not traffic compared to the interstates, I-5 or I-15. These are not a turn by turn directions, but if you look at a map or mapping application you will get the idea.

Hope this helps.

I-10 to Phoenix, then 93/60 to Henderson Nv. then I-15 north to Salt Lake, then 84 north/west to I-5 north to OLY

I just Google Mapped the route, always a good place to start. Google's primary route avoids Kali - Tucson to Phoenix to Vegas then north. Try it. Curious, how are you getting to Tucson?

To Las Vegas, to the I-15. You can tow 80mph in UT.
