I retired from MN/DOT. In a number of states if you search their web-sites you can probably find live camera feeds, which I bookmark before I travel. Also some have current weather and road conditions at interstate rest areas.
9-10 years ago I got a call at home in MN,from my oldest daughter asking for road conditions on, Snoquami Pass, in Washington State. I found a live video feed and gave her a traffic report via cell phone. She was traveling from Seattle to Spokane to visit her sister.
