The investors planned for a road to come through from Virginia Beach, Virginia, to allow access to the lots; however, these plans were abandoned in 1973 when the Back Bay National Wildlife Refuge south of Sandbridge was closed to all vehicular traffic, except by permit. Development pushed south through the 1970s, creating well over 1,000 additional lots in several subdivisions. In 1984 the residents of Corolla succeeded in their attempts to gain a public access road from the south. The state began paving the extension of NC-12 toward the north.
