The Herbert C. Bonner Bridge, being replaced by a new bridge that's set for completion in 2019, arches for 3 miles over Oregon Inlet and carries traffic to Hatteras Island, a 42-mile-long curved ribbon of sand and starkly beautiful dunes dividing the Atlantic Ocean and Pamlico Sound. At its most distant point (Cape Hatteras), the island is 25 miles from the mainland. About 88% of the island belongs to Cape Hatteras National Seashore and the state of North Carolina; the remainder is privately owned in seven quaint villages strung along the two-lane NC Route 12, the only main road on the island.
Hatteras Island is known as the blue marlin (or billfish) capital of the world. The Continental Shelf, 40 miles offshore, and its current, combined with the nearby Gulf Stream and Deep West Boundary Current, create an unparalleled fish habitat. The total population of the seven villages—from north to south, Rodanthe, Waves, Salvo, Avon, Buxton, Frisco, and Hatteras Village—is around 4,500, but in summer when the hundreds of vacation rental houses fill up, the island's population swells by several-fold. There are not many motels on Hatteras as most visitors stay in vacation houses. Avon is the village with the largest number of vacation rentals. Large waterfront houses with 6 to 10 bedrooms, private swimming pool, an elevator, and even a movie theater can go for $15,000 or more a week in summer, although many more-modest rentals are available.
