The Sydney Harbour Bridge is a steel through arch bridge in Sydney, New South Wales, Australia, spanning Sydney Harbour from the central business district (CBD) to the North Shore. The view of the bridge, the harbour, and the nearby Sydney Opera House is widely regarded as an iconic image of Sydney, and of Australia itself. Nicknamed "The Coathanger" because of its arch-based design, the bridge carries rail, vehicular, bicycle and pedestrian traffic.
A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
A cable-stayed bridge has one or more towers, from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.
The William Jolly Bridge is a heritage-listed road bridge over the Brisbane River between North Quay in the Brisbane central business district and Grey Street in South Brisbane, within City of Brisbane, Queensland, Australia. It was designed by Harding Frew and built from 1928 to 1932 by MR Hornibrook.
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct may be made from a series of arches, although other more economical structures are typically used today.
Gladesville Bridge is a heritage-listed concrete arch road bridge that carries Victoria Road over the Parramatta River, linking the Sydney suburbs of Huntleys Point and Drummoyne, in the local government areas of Canada Bay and Hunter's Hill, in New South Wales, Australia. Despite its name, the bridge is not in Gladesville.
The eastern span replacement of the San Francisco–Oakland Bay Bridge was a construction project to replace a seismically unsound portion of the Bay Bridge with a new self-anchored suspension bridge (SAS) and a pair of viaducts. The bridge is in the U.S. state of California and crosses the San Francisco Bay between Yerba Buena Island and Oakland. The span replacement took place between 2002 and 2013, and is the most expensive public works project in California history, with a final price tag of $6.5 billion, a 2,500% increase from the original estimate of $250 million, which was an initial estimate for a seismic retrofit of the span, not the full span replacement ultimately completed. Originally scheduled to open in 2007, several problems delayed the opening until September 2, 2013. With a width of 258.33 ft (78.74 m), comprising 10 general-purpose lanes, it is the world's widest bridge according to Guinness World Records.
Falsework consists of temporary structures used in construction to support a permanent structure until its construction is sufficiently advanced to support itself. For arches, this is specifically called centering. Falsework includes temporary support structures for formwork used to mold concrete in the construction of buildings, bridges, and elevated roadways.
The Mike O'Callaghan–Pat Tillman Memorial Bridge is an arch bridge in the United States that spans the Colorado River between the states of Arizona and Nevada. The bridge is located within the Lake Mead National Recreation Area approximately 30 miles (48 km) southeast of Las Vegas, and carries Interstate 11 and U.S. Route 93 over the Colorado River. Opened in 2010, it was the key component of the Hoover Dam Bypass project, which rerouted US 93 from its previous routing along the top of Hoover Dam and removed several hairpin turns and blind curves from the route. It is jointly named for Mike O'Callaghan, Governor of Nevada from 1971 to 1979, and Pat Tillman, an American football player who left his career with the Arizona Cardinals to enlist in the United States Army and was killed in Afghanistan in 2004 by friendly fire.
The Lupu Bridge, named after Luwan District, is a through arch bridge over the Huangpu River in Shanghai, China, connecting the city's Huangpu and Pudong districts. It is the world's third longest steel arch bridge, after the Ping'nan Third Bridge in Guangxi and the Chaotianmen Bridge in Chongqing. The bridge has a total length including approach spans of 3,900 m (12,795 ft) and opened on June 28, 2003. The main bridge structure is 750m long including the two side spans of 100m each, and the main span of 550 metres (1,804 ft) over the Huangpu River is 32 metres (105 ft) longer than the previous record holder for the longest arch bridge, the New River Gorge Bridge in Fayetteville, West Virginia. It cost 2.5 billion yuan, including US$78.04 for the main steel structure alone. It is located adjacent to the former Expo 2010 site and served as the centrepiece of the world exposition in Shanghai.
Hampden Bridge is a heritage-listed single-span suspension bridge that carries Moss Vale Road (B73) across the Kangaroo River, in Kangaroo Valley, in the City of Shoalhaven local government area of New South Wales, Australia. The bridge was designed by Ernest de Burgh and built by Loveridge and Hudson. The property is owned by Transport for NSW. It was added to the New South Wales State Heritage Register on 2 August 2019.
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.
The M5 is an expressway in the City of Cape Town Metropolitan Municipality, South Africa. It connects Milnerton on the Western Seaboard in the north to Muizenberg in the south, and crosses both the N1 and the N2. For part of its length, from the N1 interchange to Plumstead, it is a limited-access freeway (motorway). From Mowbray to Muizenberg, it is parallel to the M4 Main Road.
A tied-arch bridge is an arch bridge in which the outward horizontal forces of the arch(es) caused by tension at the arch ends to a foundation are countered by equal tension of its own gravity plus any element of the total deck structure such great arch(es) support. The arch(es) have strengthened chord(s) that run to a strong part of the deck structure or to independent tie-rods below the arch ends.
Wylam Railway Bridge is a footbridge and former railway bridge crossing the River Tyne at Hagg Bank, approximately 1⁄2 mile (0.8 km) west of Wylam in Northumberland, England.
The Incheon Bridge is a reinforced concrete cable-stayed bridge in South Korea. At its opening in October 2009, it became the second bridge connection between Yeongjong Island and the mainland of Incheon. The Incheon Bridge is South Korea's longest spanning cable-stayed bridge. In comparison, it is the world's tenth longest cable-stayed bridge as of January 2019.
The Hampden County Memorial Bridge is a reinforced-concrete arch bridge that spans the Connecticut River between Springfield, Massachusetts and West Springfield, Massachusetts, constructed in 1922.

The East River Bridge is a multi-span bridge in Sheet Harbour, Nova Scotia that carries Trunk 7 and the Marine Drive scenic route over the Northeast Arm of Sheet Harbour. The bridge is 183 m (600 ft) in length and was constructed from September 2014 to December 2015. It was opened on December 17, 2015 to pedestrians, with a bridge walk commemorating the closing of the old bridge and the opening of the new bridge. The bridge was opened to vehicles the day after. It replaced a green steel arch bridge of the same name that was built in 1956 immediately north of the current bridge. The previous bridge had a span of 213 m (699 ft) and shared engineering ties with the Angus L. MacDonald Bridge in Halifax. Nova Scotia was considering repairs to the old bridge, but they ultimately elected to construct a new bridge instead. The current bridge was designed without overhead arches, unlike its predecessor, as the construction cost would have been doubled.
