The Queen's Highway, a two lane paved and illuminated road without traffic lights or stop signs, runs approximately 40 miles from the northernmost edge of South Andros which is the port of Drigg's Hill, to the dockside settlement of Mars Bay. At Mars Bay the road ends in a cul de sac but the island extends approximately 20 further miles south without roads or services, inaccessible except by boat. In its course from Drigg's Hill to Mars Bay, the highway crosses two bridges, one at Deep Creek and one further south at Little Creek, both built within the past 30 years.
Almost the entire population of South Andros lives in housing abutting the Queen's Highway and a few short, unpaved "sand roads" trailing off it. The only other significant road is that leading west, inland, along the edge of Deep Creek, to Black Point, where there are a handful of additional homes. South Andros' widest point is about 20 miles east to west, but only the eastern fringe is inhabited, as most of the island consists of salty marsh and tidal estuaries.
All housing on South Andros consists of small, single family homes, sometimes clustered in small groups on a single tract of land, and almost all buildings are made of cement block and/or local limestone, as wood is expensive to import and does not withstand hurricanes well. Government provided electric, telephone and rubbish disposal services are available to all homes on the island, with a major power generation plant located mid-island in the settlement called The Bluff or Blufftown. Municipal water is supplied to much of the island inhabitants but for residents in the southern part of the island, water is obtained by catchment or private well: many parts of Andros enjoy an abundance of underground fresh water lenses. Natural gas is purchased by the tank, brought in weekly by mail boat from Nassau.
South Andros is known for the production of certain seasonal delicacies, fresh conch, land crab, and spiny lobster, in relative abundance, which are sold commercially in Nassau or to the representatives of Nassau food distributors, providing an important source of cash to many inhabitants. The only other current industry of note is tourism. Albeit limited, there is a small lucury lodge, a traditional hotel and as well the management of "bonefish lodges," small hotels which offer all-inclusive packages for tourists wishing to fish the world famous "bonefish flats" of the southeastern fringe of the island. As of summer 2018, there were 4-6 such lodges in operation, each maintaining 4-12 guest rooms. The very low level of tourist traffic supports few restaurants and almost no shops aside from the necessary basic hardware and grocery stores.
South Andros is also the origins of many notable Bahamians like Lady Pindling (the wife of Sir Lynden Pindling), Picewell Forbes (longtime radio personality and current Member of Parliament for South Andros), Dr Leon Higgs (former President of the College of the Bahamas) and well known Businessman Tiger Finlaysson. The majority of South Andros residents are members of either Baptist or Seventh-day Adventist Church congregations, with a few Catholic and other denominations represented by a church or two. There are no movie theatres, video rental stores, chain restaurants, major hotels, or major car rental agencies on South Andros; however, Bank of the Bahamas are open on Mangrove Cay Monday and Thursday. In Kemp`s Bay South Andros Tuesday and Friday.
