Golden Gate Bridge

The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean. The structure links the American city of San Francisco, California – the northern tip of the San Francisco Peninsula – to Marin County, carrying both U.S. Route 101 and California State Route 1 across the strait. The bridge is one of the most internationally recognized symbols of San Francisco, California, and the United States. It has been declared one of the Wonders of the Modern World by the American Society of Civil Engineers.

Brooklyn Bridge

The Brooklyn Bridge is a hybrid cable-stayed/suspension bridge in New York City and is one of the oldest roadway bridges in the United States. Started in 1869 and completed fourteen years later in 1883, it connects the boroughs of Manhattan and Brooklyn, spanning the East River. It has a main span of 1,595.5 feet (486.3 m) and was the first steel-wire suspension bridge constructed. It was originally called the New York and Brooklyn Bridge and the East River Bridge, but it was later dubbed the Brooklyn Bridge, a name coming from an earlier January 25, 1867 letter to the editor of the Brooklyn Daily Eagle and formally so named by the city government in 1915. Since opening, it has become an icon of New York City and was designated a National Historic Landmark in 1964 and a National Historic Civil Engineering Landmark in 1972.

Tower Bridge

Tower Bridge is a combined bascule and suspension bridge in London built between 1886 and 1894. The bridge crosses the River Thames close to the Tower of London and has become an iconic symbol of London. Because of this, Tower Bridge is sometimes confused with London Bridge, situated some 0.5 mi (0.80 km) upstream. Tower Bridge is one of five London bridges now owned and maintained by the Bridge House Estates, a charitable trust overseen by the City of London Corporation. It is the only one of the Trust's bridges not to connect the City of London directly to the Southwark bank, as its northern landfall is in Tower Hamlets.

Tacoma Narrows Bridge (1940)

The 1940 Tacoma Narrows Bridge, the first Tacoma Narrows Bridge, was a suspension bridge in the U.S. state of Washington that spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7 of the same year. At the time of its construction, the bridge was the third-longest suspension bridge in the world in terms of main span length, behind the Golden Gate Bridge and the George Washington Bridge.

London Bridge

Several bridges named London Bridge have spanned the River Thames between the City of London and Southwark, in central London. The current crossing, which opened to traffic in 1973, is a box girder bridge built from concrete and steel. It replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old stone-built medieval structure. This was preceded by a succession of timber bridges, the first of which was built by the Roman founders of London.

Millau Viaduct

The Millau Viaduct is a cable-stayed bridge that spans the gorge valley of the Tarn near Millau in southern France. In a Franco-British partnership, it was designed by the English architect Lord Norman Foster and French structural engineer Michel Virlogeux, and as of May 2017 it is the twenty-fourth highest bridge deck in the world, being 270 metres (890 ft) between the road deck and the ground below.

Sydney Harbour Bridge

The Sydney Harbour Bridge is a steel through arch bridge across Sydney Harbour that carries rail, vehicular, bicycle, and pedestrian traffic between the Sydney central business district (CBD) and the North Shore. The dramatic view of the bridge, the harbour, and the nearby Sydney Opera House is an iconic image of Sydney, and Australia itself. The bridge is nicknamed "The Coathanger" because of its arch-based design.

Sunshine Skyway Bridge

The Bob Graham Sunshine Skyway Bridge, known to locals as the Sunshine Skyway Bridge or more casually the Skyway, is a bridge spanning Tampa Bay, Florida, with a cable-stayed main span, and a total length of 21,877 feet. It is part of Interstate 275 (I-275) and U.S. Route 19 (US 19), connecting St. Petersburg in Pinellas County and Terra Ceia in Manatee County, Florida, passing through the waters of Pinellas County, Hillsborough County and Manatee County, Florida. Construction of the current bridge began in 1982, and the completed bridge was dedicated on February 7, 1987. The new bridge cost $244 million to build, and was opened to traffic on April 20, 1987. It replaced an older bridge constructed in 1954, which was partly destroyed in a collision in 1980.

George Washington Bridge

The George Washington Bridge is a double-decked suspension bridge spanning the Hudson River between the Washington Heights neighborhood of Manhattan in New York City, and the borough of Fort Lee in New Jersey. As of 2016, the George Washington Bridge carried over 103 million vehicles per year, making it the world's busiest motor vehicle bridge. It is owned by the Port Authority of New York and New Jersey, a bi-state government agency that operates infrastructure in the Port of New York area. The George Washington Bridge is also informally known as the GW Bridge, the GWB, the GW, or the George and formerly as the Fort Lee Bridge or Hudson River Bridge.

San Francisco–Oakland Bay Bridge

The San Francisco–Oakland Bay Bridge, known locally as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 and the direct road between San Francisco and Oakland, it carries about 260,000 vehicles a day on its two decks. It has one of the longest spans in the United States.

Øresund Bridge

The Øresund or Öresund Bridge is a combined railway and motorway bridge across the Øresund strait between Sweden and Denmark. The bridge runs nearly 8 kilometres from the Swedish coast to the artificial island Peberholm in the middle of the strait. The crossing is completed by the 4-kilometre (2.5 mi) Drogden Tunnel from Peberholm to the Danish island of Amager.

Severn Bridge

The Severn Bridge, sometimes also called the Severn–Wye Bridge, is a motorway suspension bridge operated by Highways England that spans the River Severn and River Wye between Aust, South Gloucestershire in England, and Chepstow, Monmouthshire in South East Wales, via Beachley, Gloucestershire, which is a peninsula between the two rivers. It is the original Severn road crossing between England and Wales, and took three-and-a-half years to construct at a cost of £8 million. It replaced the Aust ferry.

Verrazzano-Narrows Bridge

The Verrazano-Narrows Bridge is a double-decked suspension bridge that connects the New York City boroughs of Staten Island and Brooklyn and is named for Giovanni da Verrazzano. It spans the Narrows, a body of water linking the relatively enclosed Upper New York Bay with Lower New York Bay and the Atlantic Ocean. The bridge carries thirteen lanes of Interstate 278, with seven lanes on the upper level and six on the lower level. In 1524, da Verrazzano became the first documented European explorer to enter New York Harbor and the Hudson River. Because of a naming error, the bridge's name is spelled with only one "z", despite the explorer's name having two "z"s.

Pamban Bridge

Pamban Bridge is a railway bridge which connects the town of Rameswaram on Pamban Island to mainland India. Opened on 24 February 1914, it was India's first sea bridge, and was the longest sea bridge in India until the opening of the Bandra-Worli Sea Link in 2010. The rail bridge is, for the most part, a conventional bridge resting on concrete piers, but has a double-leaf bascule section midway, which can be raised to let ships and barges pass through. Until 1988, the Pamban bridge was the only surface transport that connected Tamil Nadu's island of Rameswaram to the mainland.

Truss bridge

A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements usually forming triangular units. The connected elements may be stressed from tension, compression, or sometimes both in response to dynamic loads. Truss bridges are one of the oldest types of modern bridges. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently.
