34-616: The Corpus Christi Harbor Bridge is a through arch bridge in Corpus Christi, Texas , that carries six lanes of U.S. Route 181 (US 181) and Texas State Highway 35 (SH 35) from downtown Corpus Christi to Rincon Point, known to locals as North Beach . The bridge crosses the Corpus Christi Ship Channel and handles nearly 26,000 vehicles daily. A new bridge called the New Harbor Bridge

68-538: A 170-year estimated life. Construction was originally slated to finish in 2020. On October 15, 2019, it was announced that the Harbor Bridge would not be completed until 2023. On November 15, 2019, design activities on the new Harbor Bridge were suspended by the Texas Department of Transportation. In a statement, the Texas Department of Transportation says it asked Flatiron Dragados, the firm building

102-675: A father of four and a local scaffolder from South Shields , died in the building of this structure. The Tyne Bridge was designed by Mott, Hay and Anderson , comparable to their Sydney Harbour Bridge version. These bridges derived their design from the Hell Gate Bridge in New York City . The Dorman Long team was also notable for including Dorothy Buchanan, the first female member of the Institution of Civil Engineers , joining in 1927; in addition to her contribution to

136-713: A semi-circular arch, the height is half of the span. Bridges across deep, narrow gorges can have their arch placed entirely beneath a flat roadway, but bridges in flatter country rise above their road approaches. A wide bridge may require an arch so tall as to become a significant obstacle and incline for the roadway. Small bridges can be hump-backed , but larger bridges such as the Old Bridge, Pontypridd may become so steep as to require steps, making their use for wheeled traffic difficult. Railways also find arched bridges difficult as they are even less tolerant of inclines. Where simple arched bridges are used for railways on flat terrain

170-406: Is associated with some of the most distinguished 20th-century civil engineers. One of its engineers being Sir Ralph Freeman, the architect of some of the most impressive bridges in the world. Freeman was a founder of Freeman Fox & Partners, renowned bridge designers worldwide. The bridge and nearby structures are used as a nesting site by a colony of around 700 pairs of black-legged kittiwakes ,

204-518: Is constructed in place or lifted into position. In some cases, this type of arch has been created by constructing cantilevers from each side, with the shoreside ends bolted securely down into heavy piers. The incomplete channel ends are then constructed toward each other and either filled by construction or by lifting a prefabricated center section. This type of construction was used in the Sydney Harbour Bridge illustrated above, with

238-697: Is no longer in use. Although a lift shaft was also included in the South tower no lift was ever installed. The bridge's design uses a parabolic arch . The bridge was originally painted green with special paint made by J. Dampney, Tonbridge, Tingate Co. of Gateshead. The same colours were used to paint the bridge in 2000. In 2012, the largest Olympic rings in the UK were erected on the bridge. The rings were manufactured by commercial signage specialists Signmaster ED Ltd of Kelso. The rings were over 25 by 12 metres (82 by 39 ft) and weighed in excess of four tonnes. This

272-399: Is not practical to support the arch from beneath during construction. In modern construction, temporary towers are erected and supported by cables anchored in the ground. Temporary cables fly from each side to support arch segments as they are constructed. When the arches are almost complete a jacking bridge is placed over or beneath the gap to force the arches apart, whence the final section

306-568: Is under construction. When complete, it will allow larger ships to pass beneath, permit safer pedestrian transit, and reconfigure the highway interchange system in the surrounding community. In 2008, local, state, and federal authorities began the replacement process. The new Harbor Bridge will be a cable-stayed suspension bridge with a 1661-foot span, rising to a height of 538 feet at the peak of each support pylon. The bridge will allow passage of ships up to 205 feet above-waterline height. The concrete construction technique used for bridge segments have

340-975: The Chaotianmen Bridge in China, the world's longest through arch bridge; Tyne Bridge of Newcastle upon Tyne ; the Bayonne Bridge that connects New York City to New Jersey , which is longer than the Sydney Harbour Bridge; the Ahwaz White Bridge ; the Bourne Bridge and Sagamore Bridge , smaller, near-twin bridges over the Cape Cod Canal ; the Pennybacker Bridge in Austin , Texas and as

374-659: The Department for Transport and the local government funded the cycled refurbishment of the bridge. The costs increased from £12 million to £32 million during the negotiation period. On 11 September 2023, work began, and estimations calculated the work would take four years. The agreement involved a full repaint of the rusted steelwork. The local governments from Newcastle and Gateshead also contracted work for critical structural repairs, including steel and concrete fixes, bridge joint replacements, drainage improvements, waterproofing and resurfacing, and parapet protection. Work on

408-676: The Hernando de Soto Bridge in Memphis, Tennessee . Wylam Railway Bridge is an early through arch bridge upstream of the Tyne Bridge. The through arch bridge usually consists of two ribs, although there are examples like the Hulme Arch Bridge of through arches with a single rib. When the two arches are built in parallel planes, the structure is a parallel rib arch bridge. When the two arch ribs lean together and shorten

442-542: The Bishops of Durham, York and Caithness. The stone bridge was constructed but then damaged by flood in 1339. Repairs proved costly and took place in sections: it was not fully repaired, as a part stone and part wooden bridge, until the 16th century and was part destroyed by a great flood in November 1771 . Following this, a new stone bridge was begun after the city council petitioned Parliament. The foundation stone on

476-555: The Tyne Bridge, she served as part of the team for the Sydney Harbour Bridge and the Lambeth Bridge in London. The bridge was completed on 25 February 1928, and officially opened on 10 October that year by King George V and Queen Mary , who were the first to use the roadway, travelling in their Ascot Landau. The opening ceremony was attended by 20,000 schoolchildren who had been given the day off. Movietone News recorded

510-413: The bridge, to suspend the design activities until a replacement for FIGG Bridge Engineers Inc. was found, after the pedestrian bridge at Florida International University ; which was designed by that company, collapsed on March 15, 2018, while it was under construction at the time of collapse. In July 2020, Arup and Carlos Fernandez Casado S.L. was hired to review, recertify, and complete the main span of

544-483: The bridge. In August 2022, TxDOT halted construction after deficiencies were found within the superstructure of the new bridge. Construction resumed in December 2022 once these problems were resolved. Through arch bridge For a specific construction method, especially for masonry arches, the proportions of the arch remain similar no matter what the size: wider arches are thus required to be taller arches. For

578-425: The cost of building long approach embankments may be considerable. Further issues are the foundations for the bridge. Arch bridges generate large side thrusts on their footings and so may require a solid bedrock foundation. Flattening the arch shape to avoid the humpback problem, such as for Brunel's Maidenhead bridge , increases this side thrust. It is often impossible to achieve a flat enough arch, simply owing to

612-405: The deck from the arch by tension rods, chains or cables and allow a gap in the arch, so the deck can pass through it. The first of these in particular cannot be achieved with masonry construction and requires wrought iron or steel. The use of a through arch does not change the proportions or size of the arch: a large span will still require a tall arch, although this can now reach any height above

646-495: The deck without obstructing traffic. The arch may also reach downwards at its sides, to either reach strong foundations or to place the roadway at a convenient height for spanning a deep valley from a plateau above. The Tyne Bridge demonstrates both of these advantages. A well-known example of this type is the Sydney Harbour Bridge in Australia, which is based on the Hell Gate Bridge in New York City . Other bridges include

680-491: The deliberate tension member that is the key to a tied-arch. Although visually similar, tied- and untied- through-arch bridges are quite distinct structurally and are unrelated in how they distribute their loads. In particular, cast iron bridges such as the Stanley Ferry Aqueduct may resemble tied-arch bridges, but as cast iron is weak in tension they are not structurally a tied arch. In some locations it

714-408: The distance between the arches near the top, the span is a basket handle arch bridge. Many tied-arch bridges are also through-arch bridges. As well as tying the side-loads of the arch, the tension member is also at a convenient height to form the bridge deck, as for a through-arch. The converse is not true: through-arch bridges do not imply that they are tied-arch bridges, unless they also provide

748-525: The furthest inland in the world. The colony featured in the BBC's Springwatch programme in 2010. Several groups, including the Natural History Society of Northumbria and local Wildlife Trusts, formed a "Tyne Kittiwake Partnership" to safeguard the colony. A proposal for a tower to be built as an alternative nesting site was made in 2011, and in November 2015 a neighbouring hotel submitted

782-403: The limitations of the foundations – particularly in flat country. Historically, such bridges often became viaducts of multiple small arches. With the availability of iron or concrete as structural materials, it became possible to construct a through arch bridge : a bridge where the deck does not have to be carried over the top of the arch. This requires a structure that can both support

816-529: The main bridge deck started in April 2024, with completion expected in time for the bridge's centenary in 2028. On 23 August 2018, the bridge was Grade II* listed by Historic England . The rating means the bridge is a particular important structure of more than special interest. The bridge was upgraded by the Department for Digital, Culture, Media and Sport on the advice of Historic England. The bridge

850-455: The north side was laid by Sir Matthew White Ridley on 25 April 1775, with the south side foundation stone laid in 1776. Works were completed by 13 September 1779, at an estimated cost of between £30,000 and £60,000. Work on a modern bridge started in August 1925, with Dorman Long acting as the building contractors. Despite the dangers of the building work, only one worker, Nathaniel Collins,

884-456: The prototype of a method of construction involving progressive cantilevering, using cables, cradles and cranes, which was also developed for Sydney Harbour, but first tested in Newcastle; its neoclassical and Art Deco towers that are well-detailed and defined; a potent symbol of the character and industrial pride of Tyneside; recognised worldwide for its dramatic design. Historic interest: it

918-574: The speech given by the King. The Tyne Bridge's towers were built of Cornish granite and were designed by local architect Robert Burns Dick as warehouses with five storeys. But, the inner floors of the warehouses in the bridge's towers were not completed and, as a result, the storage areas were never used. A lift for passengers and goods was built in the North tower to provide access to the Quayside ; it

952-628: The supporting cables to the higher side of the arches removed after completion. Tyne Bridge The Tyne Bridge is a through arch bridge over the River Tyne in North East England , linking Newcastle upon Tyne and Gateshead . The bridge was designed by the engineering firm Mott, Hay and Anderson , who later designed the Forth Road Bridge , and was built by Dorman Long and Co. of Middlesbrough . The bridge

986-471: Was a host city for the Rugby World Cup. Three matches were played at St James's Park, the home of Newcastle United Football Club. In recognition, a large illuminated sign was erected on Tyne Bridge. Similarly, the bridge was depicted in an official BBC trailer for the 2021 Rugby League World Cup (in reference to Newcastle being one of the host cities ). On 13 November 2017, the Tyne Bridge

1020-535: Was in preparation for Newcastle hosting the Olympic football tournament, and the Olympic torch relay, in which Bear Grylls zipwired from the top of the arch, to Gateshead quayside. On 28 June 2012, a large lightning bolt struck the Tyne Bridge. It lit up the roads as the sky was very dark. The bolt, part of a super-cell thunderstorm, came with heavy rain – a month's worth of rainfall in just two hours – causing flash flooding on Tyneside. In 2015, Newcastle upon Tyne

1054-525: Was involved in one of the key moments for the struggle for civil rights in 1965. 24 roads around the Tyne Bridge were closed for the day long event. The Freedom of the Tyne event featured the many civil right stories from history. The final event, revolved around the Jarrow Crusade which was described as a memorable closing to the finale. The bridge had a major refurbishment in 2001. In June 2022,

1088-510: Was officially opened on 10 October 1928 by King George V and has since become a defining symbol of Tyneside . It is ranked as the tenth tallest structure in Newcastle . The earliest bridge across the Tyne, Pons Aelius , was built by the Romans on the site of the present Swing Bridge around 122. A series of wooden bridges were lost to fire or flood, and plans for a stone bridge were begun in about 1250 with support from local landowners, and

1122-630: Was the venue for the Freedom on the Tyne finale, the finale of the 2017 Freedom City festival. The festival commemorated Newcastle's civil rights history and the 50 years since Dr Martin Luther King's visit to Newcastle, where King received his honorary degree from Newcastle University . Newcastle University and Freedom City 2017 wanted to use the Tyne Bridge to symbolically hark back in history to Edmund Pettus Bridge in Selma, Alabama where King
