last I heard Ellsworth Airforce Base to Chaimberlain is closed. Then a chunk to Sturgis is open and then closed again to Wyoming... that was at the 6 pm news.
Last I heard to 94 from Bismarck west to Dickinson at least is closed from snow and a chunk of 94 near Fargo is closed due to flooding but it sounded like there was a detour. All the roads here in south central ND are glare ice now. Should be good riding if you can get out there though.
It's closed from the SD/WY line west to Gillette as of right now too.
Sounds like it is probably plowed out but they are waiting for SD to open before they lift the gates.
