This list of bridges in the United States is organized by state and includes notable bridges (both existing and destroyed) in the United States. There are more than 600,000 bridges in the U.S.
The Intracoastal Waterway (ICW) is a 3,000-mile (4,800 km) inland waterway along the Atlantic and Gulf of Mexico coasts of the United States, running from Massachusetts southward along the Atlantic Seaboard and around the southern tip of Florida, then following the Gulf Coast to Brownsville, Texas. Some sections of the waterway consist of natural inlets, saltwater rivers, bays, and sounds, while others are artificial canals. It provides a navigable route along its length without many of the hazards of travel on the open sea.
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 swing 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.
The Stone Arch Bridge is a former railroad bridge crossing the Mississippi River at Saint Anthony Falls in downtown Minneapolis, Minnesota. It is the only arched bridge made of stone on the entire Mississippi River. It is the second oldest bridge on the river next to Eads Bridge. The bridge was built to connect the railway system to the new Union Depot, which at that time was planned to be built between Hennepin Avenue and Nicollet Avenue. The bridge was completed in 1883, costing $650,000 at the time. 117 Portland Avenue is the general address of the historic complex.
State Road A1A (SR A1A) is a major north–south Florida State Road consisting of seven separate sections running a total of 338.752 miles (545.168 km) along the Atlantic Ocean, from Key West at the southern tip of Florida, to Fernandina Beach, just south of Georgia on Amelia Island. It is the main road through most oceanfront towns. Part of SR A1A is designated the A1A Scenic and Historic Coastal Byway, a National Scenic Byway. A portion of SR A1A that passes through Volusia County is designated the Ormond Scenic Loop and Trail, a Florida Scenic Highway. It is also called the Indian River Lagoon Scenic Highway from State Road 510 at Wabasso Beach to U.S. Route 1 in Cocoa. SR A1A is famous worldwide as a center of beach culture in the United States, a scenic coastal route through most Atlantic coastal cities and beach towns, including the unique tropical coral islands of the Florida Keys. SR A1A also serves as a major thoroughfare through Miami Beach and other south Florida coastal cities.
Dr. John Alexander Low Waddell was a Canadian-American civil engineer and prolific bridge designer, with more than a thousand structures to his credit in the United States, Canada, as well as Mexico, Russia, China, Japan, and New Zealand. Waddell’s work set standards for elevated railroad systems and helped develop materials suitable for large span bridges. His most important contribution was the development of the steam-powered high-lift bridge. Waddell was a widely respected writer on bridge design and engineering theory, as well as an advocate for quality in higher education engineering programs. The company he founded in 1887, 'J.A.L. Waddell, Consulting Engineer,' would eventually become the modern day Hardesty & Hanover, a leading moveable bridge engineering firm. Many of Waddell's surviving bridges are now considered historic landmarks.
State Road 60 is an east–west route transversing Florida from the Gulf of Mexico to the Atlantic Ocean. The western terminus of SR 60 is at the Sunsets at Pier 60 site in Clearwater Beach. The eastern terminus is in Vero Beach near the Atlantic Coast just past State Road A1A.
The National Register of Historic Places in the United States is a register including buildings, sites, structures, districts, and objects. The Register automatically includes all National Historic Landmarks as well as all historic areas administered by the U.S. National Park Service. Since its introduction in 1966, more than 90,000 separate listings have been added to the register.
The Industrial Canal is a 5.5 mile (9 km) waterway in New Orleans, Louisiana, United States. The waterway's proper name, as used by the U.S. Army Corps of Engineers and on NOAA nautical charts, is Inner Harbor Navigation Canal (IHNC). The more common "Industrial Canal" name is used locally, both by commercial mariners and by landside residents.
Transportation in the Commonwealth of Virginia is by land, sea and air. Virginia's extensive network of highways and railroads were developed and built over a period almost 400 years, beginning almost immediately after the founding of Jamestown in 1607, and often incorporating old established trails of the Native Americans.
Buildings, sites, districts, and objects in New York listed on the National Register of Historic Places:
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).
The Haulover Canal is a waterway north of Merritt Island, Florida, near the former site of Allenhurst, that connects Mosquito Lagoon with the Indian River, and is part of the Intracoastal Waterway.
The George and Cynthia Mitchell Memorial Causeway is a set of causeways in Galveston, Texas, United States. Two of the routes carry the southbound and northbound traffic of Interstate 45, while the original causeway is restricted to rail traffic. It is the main roadway access point to Galveston Island. The second access point is Bolivar Ferry.
The King Iron Bridge & Manufacturing Company was a late-19th-century bridge building company located in Cleveland, Ohio. It was founded by Zenas King (1818–1892) in 1858 and subsequently managed by his sons, James A. King and Harry W. King and then his grandson, Norman C. King, until the mid-1920s. Many of the bridges built by the company were used during America's expansion west in the late 19th century and early 20th century, and some of these bridges are still standing today.
The Hill to Hill Bridge is a road crossing of the Lehigh River and linking the south and north sides of Bethlehem, Pennsylvania in the Lehigh Valley region of eastern Pennsylvania.
