Chesapeake Bay Bridge in the context of "U.S. Route 50 in Maryland"

The Chesapeake Bay (/ˈtʃɛsəpiːk/ CHESS-ə-peek) is the largest estuary in the United States. The bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula, including parts of the Eastern Shore of Maryland, the Eastern Shore of Virginia, and the state of Delaware. The mouth of the bay at its southern point is located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the bay's 64,299-square-mile (166,534 km) drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia, and West Virginia) and all of Washington, D.C.

The bay is approximately 200 miles (320 km) long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocean. It is 2.8 miles (4.5 km) wide at its narrowest (between Kent County's Plum Point near Newtown in the east and the Harford County western shore near Romney Creek) and 30 miles (48 km) at its widest (just south of the mouth of the Potomac River, which divides Maryland from Virginia). Total shoreline including tributaries is 11,684 miles (18,804 km), circumnavigating a surface area of 4,479 square miles (11,601 km). Average depth is 21 feet (6.4 m), reaching a maximum of 174 feet (53 m). The bay is spanned twice, in Maryland by the Chesapeake Bay Bridge from Sandy Point (near Annapolis) to Kent Island and in Virginia by the Chesapeake Bay Bridge–Tunnel connecting Virginia Beach to Cape Charles.

Sandy Point State Park is a public recreation area on Chesapeake Bay, located at the western end of the Chesapeake Bay Bridge in Anne Arundel County, Maryland. The state park is known for the popularity of its swimming beach, with annual attendance exceeding one million visitors. The park grounds include the Sandy Point Farmhouse, which is listed on the National Register of Historic Places. The historic Sandy Point Shoal Lighthouse stands in about five feet of water some 1,000 yards (910 m) east of the park's beach.

Kent Island is the largest island in the Chesapeake Bay and a historic place in Maryland, United States. To the east, a narrow channel known as the Kent Narrows barely separates the island from the Delmarva Peninsula, and on the other side, the island is separated from Sandy Point, an area near Annapolis, by roughly four miles (6.4 km) of water. At only four miles wide, the main waterway of the bay is at its narrowest at this point and is spanned here by the Chesapeake Bay Bridge. The Chester River runs to the north of the island and empties into the Chesapeake Bay at Kent Island's Love Point. To the south of the island lies Eastern Bay. The United States Census Bureau reports that the island has 31.62 square miles (81.90 km) of land area.

Kent Island is part of Queen Anne's County, Maryland, and Maryland's Eastern Shore region. The first English establishment on the island, Kent Fort, was founded in 1631, making Kent Island the oldest English settlement within the present day state of Maryland and the third oldest permanent English settlement in what became the United States—after Jamestown, Virginia (1607), and Plymouth, Massachusetts (1620). The census-designated places of Stevensville and Chester are located on the island, along with several other communities, including the fishing community of Kent Narrows, which is located partially on the island. Although all of Kent Island's communities are unincorporated, the census designated places of Stevensville and Chester on the island are both more populous than any of Queen Anne's County's incorporated towns.

Stevensville is a census-designated place (CDP) in Queen Anne's County, Maryland, United States, and is the county's most populous place among both CDPs and municipalities. The community is the eastern terminus of the Chesapeake Bay Bridge. The Stevensville Historic District is one of two registered historic districts in the county, the other being the Centreville Historic District.

Sandy Point Shoal Light is a brick three story lighthouse on a caisson foundation that was erected in 1883. It lies about 0.6 mi (0.97 km) off Sandy Point, north of the Chesapeake Bay Bridge, from whose westbound span it is readily visible.

The current light replaced a brick tower on the point itself, integral to the keeper's house, which was erected in 1857. By 1874 the Lighthouse Board complained that the extent of the shoal and the poor equipment of the lighthouse made a new light necessary; appropriations were not forthcoming, however, until 1882. The whole gamut of light sources has been run, from oil wicks to incandescent oil vapor (1913) to electricity (1929). The characteristic changed from flashing to fixed and back to flashing along with the change in light source. The present light is powered by a pair of solar panels attached to the roof on the south side.
