 Initially , long @-@ term solutions to the Isabel Inlet such as building a bridge or a ferry system were considered , though they were ultimately cancelled in favor of pumping sand and filling the inlet . Coastal geologists were opposed to the solution , stating the evolution of the Outer Banks is dependent on inlets from hurricanes . Dredging operations began on October 17 , about a month after the hurricane struck . The United States Geological Survey used sand from the ferry channel to the southwest of Hatteras Island , a choice made to minimize impact to submerged aquatic vegetation and due to the channel being filled somewhat during the hurricane . On November 22 , about two months after the hurricane struck , Highway 12 and Hatteras Island were reopened to public access . On the same day , the ferry between Hatteras and Ocracoke was reopened . The breach on the southern end of Hatteras Island was filled in with sand , as well .
