Parts of the Florida Keys, the low-lying islands which bore the brunt of Hurricane Irma when the category four storm struck on Sunday, are to re-open.
Entry is being restricted to residents and business owners as work continues to clear roads and check the state of bridges linking the islands.
Sixty per cent of homes in the state are still without power.
Irma, which has since rapidly weakened, is being linked to 11 deaths in the United States.
Seven people died in Florida, three in Georgia and one in South Carolina.
The storm also left a trail of destruction in the Caribbean, where at least 37 people were killed.
