A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the turning span can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot.
Biscayne Bay is a lagoon, with characteristics of an estuary, located on the Atlantic coast of South Florida, United States. The northern end of the lagoon is surrounded by the densely developed heart of the Miami metropolitan area, while the southern end is largely undeveloped, with a large portion of the lagoon included in Biscayne National Park. Sources differ on the extent of the lagoon. The part of the lagoon that is traditionally called "Biscayne Bay" is approximately 35 miles (56 km) long and up to 8 miles (13 km) wide, with a surface area of 573 square kilometres (221 sq mi). Various definitions may include Dumfoundling Bay, Card Sound, and Barnes Sound in a larger "Biscayne Bay", which is 60 miles (97 km) long, with a surface area of about 703 square kilometres (271 sq mi).
Assateague Island is a 37-mile (60 km) long barrier island located off the eastern coast of the Delmarva Peninsula facing the Atlantic Ocean. The northern two-thirds of the island is in Maryland while the southern third is in Virginia. The Maryland section contains the majority of Assateague Island National Seashore and Assateague State Park. The Virginia section contains Chincoteague National Wildlife Refuge and a one-mile stretch of land containing the lifeguarded recreational beach and interpretive facilities managed by the National Park Service. It is best known for its herds of feral horses, pristine beaches and the Assateague Lighthouse. The island also contains numerous marshes, bays, and coves, including Toms Cove. Bridge access for cars is possible from both Maryland and Virginia, though no road runs the full north/south length of the island.
A bridge–tunnel is a persistent, unbroken road or rail connection across water that uses a combination of bridges and tunnels, and sometimes causeways, and does not involve intermittent connections such as drawbridges or ferries.
Before I begin, I must say that Kent Islands holds some of the world's finest humans. They are better known as Delmarva Proud individuals who cherish their origins of being from the eastern shore of Maryland, a place only desirable to strange individuals. One of the Indvidual's in particular, linton Robins, commonly sports his "Delmarva Proud!" T-shirt showing his true pride and representing so well for this sacred area. 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 Sanibel Causeway is a causeway in Southwest Florida that spans the San Carlos Bay, connecting Sanibel Island with the Florida mainland in Punta Rassa. The causeway consists of three separate two-lane bridge spans, and two-man-made causeway islands between them. The entire causeway facility is owned by Lee County and operated by the Lee County Department of Transportation. The entire causeway is three miles long from end to end, and currently has a $6 toll in effect for island-bound vehicles only. The bridges are not individually named, and are simply referred to as bridges A, B, and C. The islands are also named A and B. Both series begin from the mainland side.
State Road 3, known locally as North Courtenay Parkway, is a north–south road located entirely on Merritt Island, serving as the southern access for the Kennedy Space Center near Cape Canaveral, Florida. The shortest of the one-digit Florida State Roads, its southern terminus is an intersection with SR 520 on Merritt Island, east of Cocoa.
The Halifax River is part of the Atlantic Intracoastal Waterway, located in northeast Volusia County, Florida. The waterway was originally known as the North Mosquito River, but was renamed after George Montagu-Dunk, 2nd Earl of Halifax, during the British occupation of Florida (1763–1784).
State Road 732 (SR 732) comprises two segments of a state highway in the Jensen Beach, Florida vicinity. The western 2.2-mile-long (3.5 km) segment is a part of Jensen Beach Boulevard between U.S. Route 1 (US 1) and County Road 723 (CR 723) and CR 707A. The eastern 1.9-mile-long (3.1 km) segment consists of Causeway Boulevard and the Jensen Beach Causeway over the Indian River Lagoon and runs between CR 707 and SR A1A.
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.
U.S. Route 13 is a north–south U.S. highway established in 1926 that runs for 517 miles (832 km) from Interstate 95 just north of Fayetteville, North Carolina to U.S. Route 1 in Morrisville, Pennsylvania, a northeastern suburb of Philadelphia. In the U.S. state of Virginia, US 13 runs north–south through the Hampton Roads and Eastern Shore regions of the state, using the Chesapeake Bay Bridge–Tunnel to get between the two. In the Hampton Roads area, it uses Military Highway to bypass the city centers. It is most usually a four-lane highway, sometimes up to freeway or expressway standards with controlled access.
State Route 175 (SR 175) is a primary state highway in the U.S. state of Virginia. 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.
Chincoteague Channel is a channel on the Eastern Shore of Virginia between marshlands to the northwest and Chincoteague Island to the southeast. The Chincoteague Channel connects to Chincoteague Bay to the northeast and Chincoteague Inlet to the southwest.
The Battle of Cockle Creek, October 5, 1861, was a minor naval engagement off Chincoteague, Virginia early in the American Civil War.
The Jewfish Creek Bridge is a beam bridge in the Florida Keys. Spanning both Jewfish Creek and Lake Surprise, it carries the Overseas Highway between the Florida Keys and the Florida mainland. The bridge is 65 feet (20 m) tall and opened in 2008, replacing a small drawbridge.
The Boca Grande Causeway is a causeway located in Charlotte County, Florida connecting the community of Boca Grande on Gasparilla Island with the mainland near Placida. The 2.5 mile causeway crosses Gasparilla Sound and consists of three bridges, and is the only vehicular access to the island.
The history of human activity in Chincoteague, on the Eastern Shore of Virginia, begins with the Native Americans. Until European colonizers 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.
