A swing bridge is a movable bridge that can be rotated horizontally around a vertical axis.

Kent Island is the largest island in the Chesapeake Bay and a historic place in Maryland. 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 km2) of land area.

The causeway is 3 miles (5 km) long with a $6 toll for island-bound vehicles only.

The Kent Narrows, also known as Kent Island Narrows and to local residents simply as the Narrows, is a waterway that connects the Chester River with the Eastern Bay and also separates Kent Island from the Delmarva Peninsula. It runs through the community of Kent Narrows, Maryland. The Kent Narrows was originally shallow and surrounded by marsh. A causeway was built across it in 1826, but was removed in 1876 when the channel was dredged. Today the Kent Narrows continues to be dredged regularly. The area has traditionally been a location for seafood packing and restaurants.

Known as Chincoteague Road, the state highway runs 10.49 miles (16.88 km) from U.S. Route 13 (US 13) at Nash Corner east to Main Street in Chincoteague. SR 175 passes through the northeastern corner of Accomack County, providing the primary access to NASA's Wallops Flight Facility and both Chincoteague Island and the Virginia portion of Assateague Island. The route travels between the mainland and Chincoteague Island along the John B. Whealton Memorial Causeway.
The Matanzas Pass Bridge is a bridge located in Fort Myers Beach, Florida. It carries State Road 865 between the Florida mainland and Estero Island, which is a major tourist destination. The bridge is one of the island's two connections to the mainland. The other is the Bonita Beach Causeway on the south end of the island.

Chincoteague Bay is a lagoon between the Atlantic barrier islands of Assateague and Chincoteague and the mainland of Worcester County, Maryland and northern Accomack County, Virginia. At the bay's northern end, where it narrows between Assateague and Sinepuxent Neck, it becomes Sinepuxent Bay; Chincoteague Bay's southern end drains into the Atlantic Ocean via Queen Sound and Chincoteague Inlet. No major river flows into Chincoteague Bay—its largest tributaries are Newport Creek in Worcester County and Swans Gut Creek in Accomack County.

The history of human activity in Chincoteague, on the Eastern Shore of Virginia, begins with the Native Americans. Until European explorers possessed the island in the late 17th century, the Chincoteague Indians used it as a place to gather shellfish, but are not known to have lived there; Chincoteague Island lacked suitable soil for their agriculture. The island's name derives from those early visitors: by one popular tale, chincoteague meant "Beautiful land across the water" in their language.
