Whenever the President (any President) makes a visit the Secret Service although in charge of his security coordinates with state and local law enforcement. But could a governor or mayor just say “We can’t stop POTUS from visiting, but we’re not going to make it easy.” and not allow state/local police to cooperate with the SS or close roads?

Really. And what’s more, it wouldn’t matter in the slightest whether the president was a Democrat or a Republican, or whether Congress was controlled by his party. A state or local government challenging the Feds like that would not be well-received.
