The Arkansas Highway Transportation Department provides a very handy Road Conditions Map. Below is the non-interactive version of their map. You can visit the AHTD site for a more elaborate road conditions map or a text only listing of road conditions which may be easier to use for some people.
The AHTD has a phone number people can call for weather related road conditions. It is (501) 569-2374. That sounds like a good number to have in your cell phone for when you do not have Internet access.
