State parks here are all closed, too.
Although there’s one where there are 2 parallel state highways running N-S 5 to 10 miles apart and no E-W connector for maybe 25 miles EXCEPT for the park access road. The access road thru the park itself belongs to the state dept of natural resources, about 3 miles, with county roads connecting it to the highways. So if the park was locked down, the county residents would be highly inconvenienced. So the road is always open but one isn’t supposed to stop in the park, which is nominally closed and constantly patrolled by park rangers.
There’s also a national forest, rather large, with state & county roads running thru it. They just close the park facilities and roads, pretty much.
