It’s no secret that the Hilton Head Island Airport is growing. The $10 million grant will fund the terminal expansion, ”specifically targeting increased airline traffic, meeting the needs of a growing number of airline customers while keeping within the historical, geographical and budgetary boundaries of Beaufort County’s development plans,” Rembold said. Hilton Head’s grant is part of a larger program that awarded $779 million to airports, “especially those serving smaller and rural communities,” according to U.S. Secretary of Transportation Elaine Chao.
