The highways are closed but honestly the roads are not that bad. I was able to drive around a fair amount yesterday with no issues. There's some ice on bridges, as long as it's flat just go slow and roll across. Try to time it up so that you're not close to other cars on the worst spots.
The access road intersection of 281 and 1604 is the worst spot I've come across. They've put down sand/gravel on some of the busier slopes which helps a lot.
