The Millau Viaduct (French: le Viaduc de Millau) is a cable-stayed road bridge that spans the valley of the River Tarn near Millau in southern France. Designed by British architect Lord Foster in collaboration with French bridge engineer Michel Virlogeux, it is the tallest vehicular bridge in the world, with one pier's summit at 341 metres (1,118 ft)—slightly higher than the Eiffel Tower and only 40 m (132 ft) shorter than the Empire State Building. It was formally opened on 14 December 2004 and opened to traffic on 16 December 2004.


Location

Before the bridge was constructed, traffic had to descend into the Tarn River valley and pass along the route nationale N9 near the town of Millau, causing heavy congestion at the beginning and end of the July and August vacation season. The bridge now traverses the Tarn valley above its lowest point, linking the causse du Larzac to the causse rouge, and is inside the perimeter of the Grands Causses regional natural park.

The bridge forms the last link of the A75 (la Méridienne) autoroute, providing a continuous high-speed route south from Paris through Clermont-Ferrand to Béziers. The purpose of the A75 is to increase the speed and reduce the cost of vehicle traffic travelling along this route. Many tourists heading to southern France and Spain follow this route because it is direct and without tolls for the 340 km between Clermont-Ferrand to Béziers, except for the bridge itself.

The Eiffage group operates the viaduct as a toll bridge, with the toll currently set at €4.90 for light automobiles (€6.50 during the peak months of July and August). The bridge was constructed by the Eiffage group, which also built the Eiffel Tower, under a government contract which allows the company to collect tolls for up to 75 years.

Description

The Millau Viaduct consists of an eight-span steel roadway supported by seven concrete piers. The roadway weighs 36,000 metric tons and is 2,460 m (8,071 ft) long, measuring 32 m (105 ft) wide by 4.2 m (13.8 ft) deep. The six central spans each measure 342 m (1,122 ft) with the two outer spans measuring 204 m (670 ft). The roadway has a slope of 3% descending from south to north, and curves in plan section on a 20 km (12.4 mile) radius to give drivers better visibility. It carries two lanes of traffic in each direction.

The piers range in height from 77–246 m (253–807 ft), and taper in their longitudinal section from 24.5 m (81 ft) at the base to 11 m (36 ft) at the deck. Each pier is composed of 16 framework sections, each section weighing 2,230 metric tons. These sections were assembled on site from pieces of 60 metric tons, 4 m (13 ft) wide and 17 m (56 ft) long, made in factories in Lauterbourg and Fos-sur-Mer by Eiffage. The piers each support 97 m (319 ft) tall pylons. The piers were assembled first, together with some temporary supports, before the decks were slid out across the piers by satellite-guided hydraulic rams that moved the deck 600 mm (23.6 inches) every 4 minutes.

The viaduct is the tallest vehicular bridge in the world, nearly twice as tall as the previous tallest vehicular bridge in Europe, the Europabrücke in Austria. The proposed Strait of Messina Bridge in Italy, if constructed would be taller still and would also be the world's largest suspension bridge. Current plans call for towers 382.6 m high.

The Millau Viaduct is the second highest vehicular bridge measured from the roadway elevation. Its deck, at "almost 270 m" (886 ft) above the Tarn, is apparently slightly higher than the New River Gorge Bridge in West Virginia in the United States, which is 267 m (876 ft) above the New River. The Royal Gorge Bridge in Colorado, United States has a deck considerably higher than either, at 321 m (1,053 ft) above the Arkansas River.

Construction

The viaduct under construction, seen from the south in early 2004.

Construction began on October 10, 2001 and was intended to take 3 years, but weather conditions put work on the bridge behind schedule. A revised schedule aimed for the bridge to be opened in January 2005. The viaduct was officially inaugurated by President Chirac on December 14, 2004 to open for traffic on December 16, several weeks ahead of the revised schedule.

Preliminary studies

In initial studies, four options were examined:

  1. bypass Millau to the east, requiring two large bridges over the Tarn and the Dourbie;
  2. bypass Millau to the west (12 km longer), requiring four bridges;
  3. follow the path of Route Nationale 9, providing good access to Millau but at the cost of technical difficulties and intrusion on the town; and
  4. traverse the middle of the valley.

The fourth option was selected by the government on June 28, 1989. It consisted of two possibilities: the high solution, and the low solution, requiring the construction of a 200 m bridge to cross the Tarn, then a viaduct of 2300 m extended by a tunnel on the Larzac side. After long construction studies, the low solution was abandoned because it would have intersected the water table, had negative effects on the town, cost more, and the driving distance would have been longer.

After the choice of the high viaduct's path, five teams of architects and researchers simultaneously worked on a technical solution. The original concept for the bridge was devised by French designer Michel Virlogeux. The architects of the bridge are the British firm Foster and Partners. He worked together with the Dutch engineering firm ARCADIS, responsible for the technical design of the bridge.

The builders

Four consortia were in competition for the building contract:

  • one led by Dragados (Spanish), with Skanska (Swedish) and Bec (French);
  • Société du viaduc de Millau, made up of ASF, Egis, GTM, Bouygues Travaux Publics, SGE, CDC Projets, Tofinso (all French) and Autostrade (Italian); and
  • one led by Générale Routière, with Via GTI (French), and Cintra, Necso, Acciona, and Ferrovial Agroman (all Spanish).
  • the successful bidders, lead by the Eiffage group, product of the Fougerolles-SEA fusion, the third largest French group in public works, and the sixth largest in Europe.

The work leader is the Compagnie Eiffage du Viaduc de Millau, owner of the government contract. The construction consortium is made up of the Eiffage TP company for the concrete part, the Eiffel company for the steel roadway (Gustave Eiffel built the Garabit viaduct in 1884, a train bridge in the neighboring Cantal département), and the Enerpac company for the roadway's hydraulic supports. The engineering group Setec has authority in the project, with SNCF engineering having partial control.

Costs and resources

The bridge's construction costs amount to €394 million, with a toll plaza 6 km north of the viaduct costing an additional €20 million. The builders, Eiffage, financed the construction in return for a concession to collect the tolls for 75 years, until 2080. However, if the concession is very profitable, the French government can assume control of the bridge in 2044.

The project required about 127,000 m³ of concrete, 19,000 metric tons of steel for the reinforced concrete, and 5,000 metric tons of pre-stressed concrete for the cables and shrouds. The builder claims that the bridge's lifetime will be at least 120 years.

The builder claims that the bridge's lifetime will be at least 120 years. The Vatican (which has its own country code, .va) has an official website, radio station, and satellite TV channels. The project required about 127,000 m³ of concrete, 19,000 metric tons of steel for the reinforced concrete, and 5,000 metric tons of pre-stressed concrete for the cables and shrouds. The reason for this is that this enables mail to be sent directly to the Vatican - otherwise it would go through the postal systems of other countries, which would cause a delay in shipment to the Vatican. However, if the concession is very profitable, the French government can assume control of the bridge in 2044. People sending mail to the Vatican are adivsed to not write anything other than Vatican City State for the destination on the envelope. The builders, Eiffage, financed the construction in return for a concession to collect the tolls for 75 years, until 2080. A bit of conventional wisdom in Rome is that international mail dropped in a mailbox in the Vatican will reach its destination more quickly than one dropped only a few hundred metres away in an Italian mailbox.

The bridge's construction costs amount to €394 million, with a toll plaza 6 km north of the viaduct costing an additional €20 million. The City is served by an independent, modern telephone system and post office. The engineering group Setec has authority in the project, with SNCF engineering having partial control. A newspaper, L'Osservatore Romano, publishes daily in Italian, weekly in English, Spanish, French, German, and Portuguese, and monthly in Polish. The construction consortium is made up of the Eiffage TP company for the concrete part, the Eiffel company for the steel roadway (Gustave Eiffel built the Garabit viaduct in 1884, a train bridge in the neighboring Cantal département), and the Enerpac company for the roadway's hydraulic supports. The railway is used only to transport freight. The work leader is the Compagnie Eiffage du Viaduc de Millau, owner of the government contract. There is one heliport and a 852 m (932 yd) standard gauge (1435 mm) railway that connects to Italy's network at Rome's Saint Peter's station.

Four consortia were in competition for the building contract:. The Vatican City has no airports. He worked together with the Dutch engineering firm ARCADIS, responsible for the technical design of the bridge. Normally, for civil offenses the Italian courts will handle the disposition of these cases. The architects of the bridge are the British firm Foster and Partners. The perpetrators, who are also visitors, are rarely caught, with 90% of crimes remaining unsolved. The original concept for the bridge was devised by French designer Michel Virlogeux. Each year, hundreds of tourists fall victim to pickpockets and purse snatchers.

After the choice of the high viaduct's path, five teams of architects and researchers simultaneously worked on a technical solution. In his 2002 report to the pontifical court, Chief Prosecutor Nicola Picardi quoted statistics of 87.2% for civil offences, and 133.6% for penal offences. After long construction studies, the low solution was abandoned because it would have intersected the water table, had negative effects on the town, cost more, and the driving distance would have been longer. As a result of the Vatican having a small resident population, but millions of visitors every year, the state has the highest per capita crime rate of any nation on earth, more than twenty times higher than Italy. It consisted of two possibilities: the high solution, and the low solution, requiring the construction of a 200 m bridge to cross the Tarn, then a viaduct of 2300 m extended by a tunnel on the Larzac side. The Pope leads weekly mass and other services, and appears on religious holidays such as Easter. The fourth option was selected by the government on June 28, 1989. Tourism is an important factor in the daily life of the Vatican.

In initial studies, four options were examined:. Citizenship can be achieved by stable residence and by holding an office or job within the city. The viaduct was officially inaugurated by President Chirac on December 14, 2004 to open for traffic on December 16, several weeks ahead of the revised schedule. Clothes that show the legs above the knees are strictly banned. A revised schedule aimed for the bridge to be opened in January 2005. Men, and especially women, must adhere to strict dress codes. Construction began on October 10, 2001 and was intended to take 3 years, but weather conditions put work on the bridge behind schedule. Many workers in the Vatican City live outside its walls, including the Swiss Guard and embassy personnel.

The Royal Gorge Bridge in Colorado, United States has a deck considerably higher than either, at 321 m (1,053 ft) above the Arkansas River. A minority are senior Catholic clergy; the remainder are members of religious orders. Its deck, at "almost 270 m" (886 ft) above the Tarn, is apparently slightly higher than the New River Gorge Bridge in West Virginia in the United States, which is 267 m (876 ft) above the New River. The permanent population of the Vatican City is predominately male, although two orders of nuns live in the Vatican. The Millau Viaduct is the second highest vehicular bridge measured from the roadway elevation. The Vatican Library and the collections of the Vatican Museums are of the highest historical, scientific and cultural importance. Current plans call for towers 382.6 m high. Peter's Basilica and the Sistine Chapel are home to some of the most beautiful art in the world, which includes works by artists such as Botticelli, Bernini and Michelangelo.

The proposed Strait of Messina Bridge in Italy, if constructed would be taller still and would also be the world's largest suspension bridge. Buildings such as St. The viaduct is the tallest vehicular bridge in the world, nearly twice as tall as the previous tallest vehicular bridge in Europe, the Europabrücke in Austria. The Vatican City is itself of great cultural significance. The piers were assembled first, together with some temporary supports, before the decks were slid out across the piers by satellite-guided hydraulic rams that moved the deck 600 mm (23.6 inches) every 4 minutes. Due to the very limited territory of the Vatican state, foreign embassies to the Holy See are located in the Italian part of Rome; Italy actually hosts its own Embassy of Italy. The piers each support 97 m (319 ft) tall pylons. However, it is the Holy See that is the legal body that conducts diplomatic relations for the Vatican City in addition to the Holy See's usual diplomacy, entering into international agreements and both receives and sends diplomatic representatives.

These sections were assembled on site from pieces of 60 metric tons, 4 m (13 ft) wide and 17 m (56 ft) long, made in factories in Lauterbourg and Fos-sur-Mer by Eiffage. Providing a territorial identity for the Holy See, the State of the Vatican City is a recognized national territory under international law. Each pier is composed of 16 framework sections, each section weighing 2,230 metric tons. Most Italians employed in the Vatican do not have Vatican citizenship. The piers range in height from 77–246 m (253–807 ft), and taper in their longitudinal section from 24.5 m (81 ft) at the base to 11 m (36 ft) at the deck. Nearly all these people were dual citizens, retaining citizenship of their own countries while working at the Vatican. It carries two lanes of traffic in each direction. At the end of 2003, 552 persons held Vatican citizenship, of whom 61 were cardinals, 346 were other clergy, 101 members of the Pontifical Swiss Guard and 44 were other lay persons.

The roadway has a slope of 3% descending from south to north, and curves in plan section on a 20 km (12.4 mile) radius to give drivers better visibility. A separate Vatican City citizenship exists, enabling Vatican officials to travel on Vatican passports, and giving them diplomatic status in countries to which they are accredited. The six central spans each measure 342 m (1,122 ft) with the two outer spans measuring 204 m (670 ft). German is the official language of the Swiss Guard. The roadway weighs 36,000 metric tons and is 2,460 m (8,071 ft) long, measuring 32 m (105 ft) wide by 4.2 m (13.8 ft) deep. Italian and, to a lesser extent, other languages are generally used for most conversations, publications, and broadcasts. The Millau Viaduct consists of an eight-span steel roadway supported by seven concrete piers. The official language is Latin, the lingua franca of the Roman Empire, which has remained in use in the Roman Catholic Church.

The bridge was constructed by the Eiffage group, which also built the Eiffel Tower, under a government contract which allows the company to collect tolls for up to 75 years. There are also about 3,000 lay workers who comprise the majority of the Vatican work force, but who reside outside the Vatican. The Eiffage group operates the viaduct as a toll bridge, with the toll currently set at €4.90 for light automobiles (€6.50 during the peak months of July and August). The Vatican citizenry consists mainly of clergy, including high dignitaries, priests, nuns, as well as the famous Swiss Guard, a volunteer military force. Many tourists heading to southern France and Spain follow this route because it is direct and without tolls for the 340 km between Clermont-Ferrand to Béziers, except for the bridge itself. Almost all of Vatican City's 921 citizens live inside the Vatican's walls. The purpose of the A75 is to increase the speed and reduce the cost of vehicle traffic travelling along this route. It has its own bank, Vatican Bank.

The bridge forms the last link of the A75 (la Méridienne) autoroute, providing a continuous high-speed route south from Paris through Clermont-Ferrand to Béziers. Vatican City has used the Euro as its currency since January 1, 2002. The bridge now traverses the Tarn valley above its lowest point, linking the causse du Larzac to the causse rouge, and is inside the perimeter of the Grands Causses regional natural park. The incomes and living standards of lay workers are comparable to, or somewhat better than, those of counterparts who work in the city of Rome. Before the bridge was constructed, traffic had to descend into the Tarn River valley and pass along the route nationale N9 near the town of Millau, causing heavy congestion at the beginning and end of the July and August vacation season. This unique, non-commercial economy is also supported financially by contributions (known as Peter's Pence) from Catholics throughout the world, the sale of postage stamps and tourist mementos, fees for admission to museums, and the sale of publications. . Industries: printing and production of few mosaics and staff uniforms; worldwide banking and financial activities.


. Budget: Revenues (2003) $252 million; expenditures (2003) $264 million. It was formally opened on 14 December 2004 and opened to traffic on 16 December 2004. There are some local features, principally mists and dews, caused by the anomalous bulk of St Peter's Basilica, the elevation, the fountains and the size of the large paved square. Designed by British architect Lord Foster in collaboration with French bridge engineer Michel Virlogeux, it is the tallest vehicular bridge in the world, with one pier's summit at 341 metres (1,118 ft)—slightly higher than the Eiffel Tower and only 40 m (132 ft) shorter than the Empire State Building. Its climate is clearly mostly the same as Rome's; a temperate, Mediterranean climate with mild, rainy winters from September to mid-May and hot, dry summers from May to August. The Millau Viaduct (French: le Viaduc de Millau) is a cable-stayed road bridge that spans the valley of the River Tarn near Millau in southern France. It is the smallest sovereign state in the world at 0.44 km² (108.7 acres).

January 10, 2005: initial planned opening date. The Vatican City, one of the European microstates, is situated on the Vatican Hill in the north-western part of Rome, several hundred metres west of the Tiber river, on the latter's right bank. December 16, 2004: opening of the viaduct, ahead of schedule. It is published by Catholic laymen but carries official information. December 14, 2004: official inauguration. L'Osservatore Romano is the semi-official newspaper, published daily in Italian, and weekly in English, Spanish, Portuguese, German, and French (plus a monthly edition in Polish). 2nd half of 2004: installation of the pylons and shrouds, removal of the temporary roadway supports. Radio Vatican, the official radio station, is one of the most influential in Europe.

May 28, 2004: the pieces of roadway are several centimeters apart, their juncture to be accomplished within two weeks. The Vatican also issues its own coins and stamps and controls its own Internet domain (.va). November 2003: completion of the last piers (Piers P2 at 221 m and P3 at 245 m are the highest piers in the world.). Vatican City has its own post office, commissary (supermarket), bank (the automatic teller machines are the only ones in the world to use Latin), railway station, electricity generating plant, and publishing house. February 25–February 26, 2003: laying of first pieces of roadway. The legal system is based on canon, or ecclesiastical, law; if canon law is not applicable, special laws of the territory apply, often modelled on Italian provisions. November 2002: first piers complete. The judicial functions are handled by three tribunals — the Apostolic Signatura, the Sacra Rota Romana, and the Apostolic Penitentiary, which are also the judicial arm of the Holy See (see below).

September 2002: assembly of roadway begins. Members are cardinals appointed by the pope for terms of five years. August 2002: start of work on pier support C0. Legislative power is vested in the Pontifical Commission for Vatican City State, led by a President. July 2002: start of work on the foundations of temporary, height adjustable roadway supports. They are not really an army of the Vatican City State so much as a police force and the personal bodyguard of the Pope. June 2002: support C8 completed, start of work on piers. The Vatican City maintains a modern security corps, the famous Swiss Guards, a voluntary military force drawn from male Swiss citizens.

March 2002: start of work on the pier support C8. The Governor of Vatican City, sometime known as the President of Vatican City, has duties similar to those of a mayor or city executive, concentrating on material questions concerning the state's territory, including local security, but excluding external relations. January 2002: laying pier foundations. All decisions of these commissions must be approved by the College of Cardinals. December 14, 2001: laying of the first stone. During a sede vacante (papal vacancy), the Chamberlain of the Holy Roman Church, former Secretary of State, and former President of the Pontifical Commission form a commission that performs some of the functions of the head of state; while another made up of the Chamberlain and three cardinals (one being chosen by lot every three days from each order of cardinals), performs other functions of the head of state. October 16, 2001: work begins. These, like all other officials, are appointed by the Pope and can be dismissed by him at any time.

1998: decision to contract out both construction costs and future tolls to a private enterprise. As noted, the principal figures are the Secretary of State, the President of the Pontifical Commission for the Vatican City State, and the Governor of Vatican City. July 9, 1996: choice of the cable-stayed bridge type. For historical reasons, the government of Vatican City has a unique structure. term). In 1984, a new concordat between the Holy See and Italy modified certain provisions of the earlier treaty, including the position of Catholicism as the Italian state religion. January 10, 1995: declaration of utilité publique (public usefulness), as needed to apply eminent domain(U.S. The Lateran is on one of the seven hills of Rome, the Caelian.

October 19, 1991: selection of the high solution, with the viaduct at 2500 m. The cathedra (official seat) of the Bishop of Rome, the Pope, is in the Lateran basilica, Rome's cathedral. June 28, 1989: governmental approval of the middle route. This situation was resolved on February 11, 1929 under the premiership of Mussolini by the three Lateran treaties, which established the independent State of the Vatican City and granted Catholicism special status in Italy. €4.90–6.50: typical automobile toll, as of 2005. During this period it became fashionable to speak of the Pope as a "prisoner". 10,000–25,000 vehicles: estimated daily traffic. Other states maintained international recognition of the Holy See as a sovereign entity, and in practice Italy made no attempt to interfere with the Holy See.

290,000 metric tons: total weight of the bridge. The popes were left between 1870 and 1929 in a situation somewhat like that of the last emperor of China, undisturbed in their palace, but with no official status recognized by the Italian State. 85,000 m³: total volume of concrete used. In 1870, the Pope's holdings were left in an uncertain situation when Rome itself was annexed by the Piedmontese after a nominal resistance of the papal forces. 32.05 m: width of the roadway. For much of this time the Vatican was not the habitual residence of the Popes, but rather the Lateran Palace, and in recent centuries, the Quirinal Palace, while the residence from 1309-1377 was at Avignon in France. 4.20 m: thickness of the roadway. Popes in their secular role gradually came to govern neighbouring regions and, through the Papal States, ruled a large portion of the Italian peninsula for more than a thousand years until the mid 19th century, when most of the territory of the Papal States was seized by the newly created Kingdom of Italy.

270 m: average height of the roadway. In 326 the first church, Constantine's basilica, was built over the site of the tomb of Saint Peter, who was buried in a common cemetery on the spot, and from then on the area started to become more populated, but mostly only by dwelling houses connected with the activity of St Peter's. 154: number of shrouds. It is supposed that this originally uninhabited part of Rome (the ager vaticanus) had always been considered sacred, or at least not available for habitation, even before the arrival of Christianity. 87 m: height of a pylon. Sodano and Szoka served in their respective roles under Pope John Paul II and were then reappointed to those same roles by his successor. 336 m: height of Pier 2, the tallest (245 m at the roadway's level). Edmund Cardinal Szoka serves as both the President of the Pontifical Commission and Governor, born an American of Polish descent.

77 m: height of Pier 7, the shortest. Angelo Cardinal Sodano of Italy is the Secretary of State. 7: number of piers. The current pope is Benedict XVI, born Joseph Ratzinger in Germany. 2,460 metre: total length of the roadway. His principal subordinate government officials are the Secretary of State, the President of the Pontifical Commission for Vatican City State, and the Governor of Vatican City. the successful bidders, lead by the Eiffage group, product of the Fougerolles-SEA fusion, the third largest French group in public works, and the sixth largest in Europe.
