When roads like I-80 are closed, they are closed. I’ve spent the night (or more) waiting for them to open.
No combination of chains and tires gets you past the Sheriff or State Trooper when the road is closed.
Most National Parks are still open, but often there are parts of the park that are closed from September to May. This picture was taken in Rocky Mountain National park in late June. Behind us is the road. When they say closed, they mean it.
