Residents of Longport, Margate, and Brigantine are now being allowed back home after Gov. Christie lifted evacuation orders for those towns.
Police are allowing people with proof of home ownership or residency in the towns to return to their homes.
But Ventnor and Atlantic City remain restricted: Residents who stayed behind can leave, but those who left the island cannot return.
At the Margate Bridge Thursday afternoon, streams of cars were both entering and leaving Margate.
But Ventnor Mayor James Bagnell said the city was still attempting to fix an overwhelmed sewer system that has been filled with bay water.
