I found a very cool link for anyone traveling on Western USA highways today.
Web cams from major highways all over the western USA.
So, this service provides web cam links, accident reports and required chain-up locations for New Mexico, Colorado, Wyoming and Montana and all other states to the west of that area.
Here is the area of this service:

This is pretty incredible.
Not all of the cameras are active -- but enough are to really get a sense of the local weather in key areas of the West.
