Perhaps it allows them to begin to open borders between each other, but keep borders to other states closed? If those three states' economies are very interlinked it might let them get closer to normality.

Legally, is this possible in the US?

In Australia for example each state has closed or is controlling their borders with each other, and this seems to largely be a decision for each state (I don't think there's a federal law either way). I could imagine some states choosing to open up while others remain closed. Or if two states made big sacrifices but got the issue under control, while the others lagged behind, those two could open borders between themselves while remaining closed outside.

Great question.

The Constitution is very clear that ultimate authority about Interstate Commerce belongs to Congress. States cannot bar travel from other states.

HOWEVER there is legislation enabling states to impose quarantines on people coming from other states. https://www.nytimes.com/2020/04/10/travel/coronavirus-us-tra... has information about such quarantine rules currently in place.

So stop travel, no. Make it difficult, we're going to see a lot of that.

What in the US is legal has changed radically in the last three years.

Any particular areas? The churn of law in the US is vast, ex: taxes.
