SpaceX uses road closures to allow them to complete testing of their Starship prototypes. These can either involve closing the beach & HW4 or just closing off HW4 depending on the circumstance. Road-only closures are usually put in place for a rollout to the launch site.

There are different rules SpaceX must try their best to stick to with their closures, though. For instance, they aren't permitted to closure the beach/road in the summer month's, and they must aim to reopen the road by noon on Friday's. There are of course exceptions to these rules, but these are generally what SpaceX adhere to.

SpaceX is required to file Temporary Flight Restrictions (TFRs) in order to conduct flight tests of their Starship vehicles. These TFRs limit the airspace around the SpaceX launch facility to vehicles authorised by SpaceX only. All other aircraft are disallowed. This is to ensure that any air traffic near the launch facility stays a safe distance away during flight tests of Starship.

SpaceX has started issuing long-term, low altitude TFRs that limit aircraft from flying low above the facility. These allow SpaceX to conduct non-flight testing whenever they want without having to file for a TFR.
