EU Capital Cities


This year the Polish Post has prepared a fourth edition of the "EU Capital Cities" series issued since 2005. The stamps are accompanied by five first day envelopes FDC and one anniversary date stamp, used in Warsaw 1 Postal Office. By now we have seen representative buildings of Budapest, Berlin, Dublin, Lisbon, London, Ljubljana, Luxembourg, Madrid, Paris, Riga, Rome, Stockholm, Tallinn, Valetta and Vilnius.


Prague - the Charles Bridge
Famous for the beautiful architecture Czech capital was established upon the joining of two cities of the early Middle Ages: Hradčany and Vyšehrad. The representative for ages seat of the Czech rulers was handed over in the 16th century to the house of Habsburg, and at the same time to be dominated by Vienna. Only the so called Czech National Revival in the 19th century restored the city's previous character. Prague was again the capital city in 1918 upon the creation of Czechoslovakia. In 1993 after the split of Czechoslovakia, the city became the capital city of the Czech Republic.

The Charles Bridge (by 2nd half of the 19 century called the Stone Bridge or the Prague Bridge) connects two districts: Malá Strana and Staré Mesto. It is 515 meters long and approximately 9.5 meters wide. It was built in the 14th century (replaced the 12th century Judith Bridge destroyed by flood), by 1741 was the only bridge on the Vltava river. Its Gothic character has been emphasised by the towers protecting the bridge. The famous 30 statues of saints were added only in the times of baroque.

Gustave Alexandre Eiffel


Alexandre-Gustave Eiffel
(1832-1923), French engineer and builder, most famous for the construction of the tower in Paris that bears his name. Born in Paris, his family included artisans and timber and coal merchants. Eiffel was educated at the Lycée Royal in Dijon and the College Sainte-Barbe in Paris, and he graduated from the École Centrale des Arts et Manufactures in 1855, joining a company that produced steam engines. 

In 1858 the company was granted a contract to erect a railway bridge in Bordeaux. Eiffel oversaw the construction with such success that in 1866 he founded his own company and soon became known for his wrought-iron structures. Starting in 1872 he attracted foreign contracts, and in 1877 he erected over the Douro River in Porto (Oporto), Portugal, a steel arch bridge 160 m (525 ft) in height.


Eiffel's work combined expert craftsmanship and graceful design, qualities that are evident in the Garabit viaduct in France. Completed in 1884, it was for a time the highest bridge in the world, winning Eiffel's factory a worldwide reputation for excellence. Eiffel cast Frédéric-Auguste Bartholdi's colossal statue Liberty Enlightening the World, which was dedicated in New York in 1886. Soon after, he began work on his greatest project, the building of the Eiffel Tower. It was completed in 1889 for the celebration of the centennial of the French Revolution (1789-1799). The imposing tower—constructed of 7,000 tons of iron in 18,000 parts held together by 2,500,000 rivets—rises to a height of 300m (984 ft), and continues to dominate the Paris skyline. In the early 1890s Eiffel gave up the daily management of his business and became absorbed in the new science of aerodynamics.

Landmark Bridge of India


Mahatma Gandhi Setu
Located at Patna, Bihar, is popularly known simply as Ganga Bridge. It stands at the place where Mahatma Gandhi crossed the river long back to go to Champaran, where he laid foundations ofstruggle that was to dislodge British, and hence the name. Opened to traffic on 02.03.1982 by the then Prime Minister, late Smt. Indira Gandhi, this is the longest single river bridge in the world. The bridge consists of 45 intermediate spans of 121.065 meters each, and two end spans of 63.53 meters each, having a total length of 5,565 meters. The superstructure of the bridge is a pre-stressed cantilever construction. The completion of the Mahatma Gandhi Setu marks a milestone in the history ofthe economic development of Bihar.

Vidyasagar Setu
The modern cable bridge known as Vidyasagar Setu lies across the river Hoogly. Affording a panoramic view of the skyline of Kolkata, it itself contributes to the grandeur of the city’s new skyline. Better known locally as the second Hoogly Bridge, built to provide an additional connector between the twin cities of Kolkata and Howrah. Apart from Howrah Bridge, Vidyasagar Setu is 823 meters long, and 35 meters wide. Supported on four foundations, the height of the steel pylons over pillars is 120 meters. With a 4% longitudinal gradient, the bridge provides navigational clearance of 33.87 meter to 34.38 meter over the highest level to ensure safe passage underneath, of the international cargo ships, which cater to Kolkata Port. The bridge has also been connected with flyovers and ramps on either side to provide uninterrupted flow of traffic from both, the Kolkata and Howrah ends. This unique and longest cable stayed bridge, constructed at a cost of Rs. 380 crores, was thrown open to the nation by the hon’ble Prime Minister of India on 10th October 1992.

Howrah Bridge
The famous Howrah Bridge is one of the best known landmarks of Kolkata, a virtual ‘Gateway of Kolkata’, and an inseparable icon of the city, sharing a totemic relationship with its growth and evolution. The construction of a new ‘Suspension type balanced Cantilever Bridge’, without any intermediate pier, was conceived after the First World War, by a Committee chaired by the famous Bengali engineer and industrialist Sir R.N. Mukherjee after taking into account the hydraulic factors and the flow pattern of the river. A technological marvel, its construction was supervised by a newly formed specialized body viz., ‘The Howrah Bridge Commissioners’. Out of the 26,500 tonnes of steel used, around 3000 tonnes were imported and the rest was indigenously sourced through TISCO. The Bridge was opened to traffic in February, 1943, dismantling the earlier floating bridge. It was renamed as ‘Rabindra Setu’ on 14th June 1965, but continues to be referred to as Howrah Bridge in the popular lexicon. A suspension type balanced cantilever bridge, this is the fourth cantilever bridge in the world, with a central span of 1500 ft. between the centres of its main towers. Its anchor arms are 325 ft. long and the cantilever arms 468 ft. long at both ends, while the middle suspended span is 564 ft. The main towers soar 280 ft, high above the monoliths and are 76 ft. apart at the top. The bridge deck width is 71 ft., with two footpaths of 15 ft. on either side.

Pam ban Setu
Opened to traffic in 1914, the Pamban Bridge, also known as the Pamban Viaduct, forms part of the Rameswaram meter gauge section in Madurai Division of the Southern Railways. Constructed over 100 to 300 feet wide reef lying submerged between the mainland of India and the Island of Rameswaram, this bridge was built over the Palk Straits to reduce the gap in the rail systems between India and Sri Lanka (then Ceylon). The distance of 36 kms between Dhanushkodi, off Rameswaram Island, and Talaimannar, the railway terminus of Sri Lanka, was linked by ferry service, and direct rail cum ferry journey tickets were issued at both ends. ~ 2.06 kms long, the Pamban Bridge has 146 span of 40 feet clear, including one Scherzer lift span, which measure 213 feet, and remains a marvel of technology and a visual treat.

Bridges and Viaducts of Luxembourg


Centenary of the Adolphe Bridge
The Adolphe Bridge in Luxembourg, also called the New Bridge, opened to traffic on 24 July 1903. Built during the reign of Grand Duke Adolphe, whose name it bears, this year it celebrates its one hundred years of existence. When it was opened, this engineering project, built as an extension of Boulevard Royal to connect the western half of the upper city to the Bourbon Plateau and the central train station district, was the largest stone arch bridge ever constructed and was admired by engineers around the world. A heterogeneous combination of classical concepts and reinforced concrete, the bridge, 153 m long, features a large double arch with a span of 85 m overhanging the Pétrusse valley 42 m below. It has become a symbol of the capital and is also at the heart of the celebrations for Luxembourg National Day when it is the venue for a traditional fireworks show.


Stierchen Bridge
By following the Corniche path from the Bock rock down to the "Grund Gate", a narrow zig-zagging path leads you to the bottom of the valley and to a small footbridge, the "Stierchen". This small stone bridge in the lower town of Luxembourg called "Grund", is part of the Wenceslas wall (Wenzelsmauer), fortifications which have been added to the World Heritage List by UNESCO. The medieval Stierchen bridge dates back to the end of the 14th century whereas the wall of which it forms a part was reinforced in the 16th century to meet the needs of the artillery.


The Victor Bodson Bridge (Hesperange Viaduct)
The Victor Bodson Bridge, also known as the Hesperange Viaduct, is located on the southeast freeway bypass of Luxembourg City and spans the Alzette valley at a height of 40 m in order to connect the plateaus of Howald and Itzig. The work is a symmetric cable-stayed structure with a single central concrete pylon 61 m in height and a sheet of radial cables, each half-sheet composed of 16 cables with lengths varying from 42 to 140 m. Viewed from far away the structure resembles a majestic sailing ship. The most unusual characteristic of the bridge, however, is the curve (R = 1,750 m) of the path it follows, a very rare feature for a cable-stayed bridge.

Philippine Colonial Bridges II

Bridge building in the country is integral to the development of communities. It helps in the opening up of communities to various forms of land transport allowing thus the development of trade and relations between once distant and detached areas. The early history of bridge building was attributed to both the Spanish missionaries and conquistadors. During the early period of American rule, the Bureau of Public Works was created to initiate further the task of linking the Philippines together with spans that for some still serve the commuting public. The bridges highlight an architectural and engineering form that has served nobly the interest of the country.


Gasan Bridge, Gasan, Marinduque
Though no date was gathered pertaining to the building of the Gasan Bridge, it is known to be from the mid-to late American period. Built of concrete, the bridge spans the Matandang Gasan River. The bridge stands on plain concrete piers and is decked by concrete lattice work parapet walls. Recently, the bridge has been converted into a promenade with decorative lampposts installed and recent repainting.

Hinigaran Bridge, Hinigaran, Negros Occidental
Situated along kilometer 53 south of Bacolod in the town of Hinigaran is a 100.00 meters long Hinigaran Bridge. Spanning the river with the same name, Hinigaran Bridge was built in 1935 following a standard bridge design popularized during the time. Composed of 14 graceful piers supporting beams, the bridge, which is 6.00 meters wide, is designed with a protective parapet wall with balusters lining its side. This design which became standard for most bridges in the country still abounds throughout the archipelago. Like most American period bridges whose roadway is deemed narrow today, Hinigaran Bridge was decommissioned when the new alternative concrete bridge was constructed alongside it. Today, Hinigaran Bridge serves as a convenient platform and recreational space for "Talaba" breeders and local promenaders.

Wahig Bridge, Dagohoy, Bohol
Built in 1929, the Wahig Bridge in Dagohoy, Bohol links the inner towns of Dagohoy with Carmen, Bilar and Loboc to the south. Crossing the Wahig River, the bridge is of a single trussed span with a concrete abutment on both sides of the bridge's approach. Unlike other American era bridges which have been replaced in the past due to increasing traffic load, the Wahig bridge, being located in the interior road bisecting the island province experiences relatively light to moderate traffic load resulting in its still constant use and eventual survival.

Pan-ay Bridge, Pan-ay, Capiz
Spanning the Pan-ay River, Pan-ay Bridge is a single spanned segmented arched concrete bridge. Like most bridges built sometime in the 1930's, the Bureau of Public Works followed standard designs for most spans built around the country. Characteristic about these bridges is the use of closely spaced balusters to adorn and protect the edges of the bridge. Segmented arches were also popular in the design of the Bureau for it allowed a wider gap to be spanned compared to the rounded arch popularized by the Spanish builders which would require the building of added support piers. The Pan-ay Bridge is still much in use and connects the town proper of Pan-ay with Western towns of Capiz and Iloilo.


Quezon Bridge, Quiapo, Manila
Inaugurated in 1938, the Quezon Bridge, also referred to as the Quiapo Bridge, replaced a much earlier narrow suspension bridge, the Puente Colgante built in 1852. The bridge designed to mimic the famous Sydney Harbor Bridge is in the Art Deco style with elegant approach towers supporting the single metal trussed arched span. Unlike other bridges that span the Pasig River, Quezon Bridge has a relatively high clearance and a long northern approach which allows below its numerous supporting arches shops and stalls to be located. This has become famous for the cacophony of locally made products and handicrafts sold underneath the bridge as well as a convenient turn-around for vehicles plying the bridges access road, Quezon Boulevard. Quezon Bridge was damaged during the Second World War, and unlike other bridges that spanned the Pasig was reconstructed in 1946 following its original design.

Governor Reynold's Bridge, Guinobatan, Albay
Bridge was inaugurated in 1911 and is composed of two reinforced arched spans. Traversing the Banao River, it links the town of Guinobatan with that of Lig-ao and Camarines Sur further north. When built it cost the American colonial government P40,000 pesos. Governor Reynold's Bridge replaced an earlier span built during the Spanish colonial period in 1860 which itself was subsequently destroyed by a powerful earthquake in 1864. The bridge was designed with two reinforced concrete arch spans supporting concrete piers holding the road deck. This design was utilized by the American engineers for many similar spans found throughout the country. Governor Reynold's Bridge, which amongs the locals is more familiar as the Banao Bridge still facilitates all forms of road traffic almost a hundred years since it was inaugurated.

Mauca Railway Bridge, Ragay, Camarines Sur
Built in 1937 in time for the inauguration of the South line to Bicol in 1938, the Mauca Railway Bridge is unique not for its length but more for its uniqueness due to its construction, with box girders along its approaches and an inverted truss designed like an arch situated in the bottom of the deck crossing the river. The bridge which spans the Mauca River still carries rolling stock, from trains to the more frequent makeshift trolleys that serve most of the railway communities along the track.

Balucuan Bridge, Dao, Capiz
In the town of Dao spanning the Balucuan River in the Province of Capiz stands a single spanned bridge known as Balucuan Bridge. Though no year was gathered as to its building, its design and construction is inimical to other American period concrete arched spans such as the Governor Reynold's Bridge in Albay. The bridge is composed of only one concrete arch span that supports above its arch with small arches holding the road deck. The deck itself is only 4.40 meters wide while the bridge is roughly 20.00 meters long. Today built almost beside it, a new wider span carries the growing traffic along the main national road that links Capiz with Iloilo, Balucuan Bridge today has been sidelined and has become for the town of Dao a sort of linear garden and greeting station for those entering town.

Bridge of Taiwan (I)

Human civilizations have usually started around rivers, and bridges have continuously helped civilizations move to new realms. Today, bridges not only serve a transportation function but also spur economic and cultural development. There are different types of bridges for different geographic environments, and often bridges become fixtures in the local landscape and symbols of a locale. To introduce the beauty of Taiwan bridges, Taiwan Post is issuing a set of four stamps featuring bridges of northernTaiwan. The designs of the stamps follow:


1) The Kanjin Bridge, Taoyuan (NT$5.00):
Spanning the Dahan River, around a kilometer upstream of  the Wuling Bridge, this silver gray steel arch bridge has become a new landmark in Dasi, Taoyuan  County. The Kanjin Bridge was completed in August, 2002. It has a total length of over 800 meters and a width of over 20 meters. 


2) The Fusing Bridge, Luofu (NT$5.00):
There are two bridges that connect Luofu village with Siayunping. The lavender Fusing Bridge, completed in 1966, is an old suspension bridge with a total length of some 150 meters and a width of some 4 meters.

Bridge of New Zealand


Shotover bridge - 35c
The road bridge across the Shotover River in Central Otago was described at its opening in 1975 as "mathematical precision combined with beautiful form".  The two-lane carriageway is 320 metres long and is made up of 169 pre-cast, pre-tensioned concrete box girder sections.

Alexandra Bridge - 40c
Steel was the chosen material for the bridge built over the Clutha River at Alexandra in 1958 to replace a bridge built in 1882.  Spanning some 158 metres the new tied-steel arch bridge incorporated special design features.  It is anchored to one abutment by means of a hinge and there are bearings, or rollers on the other abutment and all the piers, that allow the bridge to freely expand and contract.

South Rangitikei Rail Bridge - 45c
The South Rangitikei rail bridge forms part of the main trunk railway line north of Mangaweka in the central North Island.  Because of the danger of flash floods and earthquakes the bridge is able to move and in the event of an earthquake the legs of the high slender piers are designed to alternatively lift off their foundations.

Twin Bridges - 70c
An unusual bridge located at the confluence of the Mangkahia and Awarua rivers in Whangarei county, Northland, is the subject of the fourth stamp.  Twin Bridges takes its name from two bridges built there in the 1920s.  These were replaced in 1970 by a single reinforced concrete structure but the name remains.  A feature of the new bridge is a 19 metre landing which branches off to give access to farm land which would otherwise be isolated by the convolutions of the two rivers.

Bridges and Engineering Structures

A bridge is a form of cultural expression, a form of sculpture with a utilitarian function; sculpture for its lines, utilitarian for its practical purpose - connect two shores or two disconnected points.
Arrabida Bridge Oporto
The Arrabida Bridge was one most innovative projects of the last century, not only in Portugal but throughout the world, however its history and building tell a tale of controversy and courage. During construction, its 270-metre span (which for same time held the world record for comparable reinforced concrete structures) and single arch attracted the attention of engineering experts from around the world, who flocked to Portugal from all corners of the earth to witness the collapse of this engineering feat designed by Edgar Cardoso. In the event, to the sheer astonishment of the era's best reputed civil engineers, the bridge did not collapse and still standing today. This is the story of the Arrabida Bridge, completed in 1963 at the peak of Edgar Cardoso's international prestige.

25 de Abril Bridge, Lisbon
Inaugurated on 6th August 1966 and a landmark of Lisbon ever since, the 25 de Abril Bridge is a road and rail suspension bridge connecting the city of Lisbon to the city of Almada and a vital element in the country's transport system. Its original name, Salazar Bridge, was changed to 25 de Abril shortly after the revolution of 25th April 1974. At the time of its construction, the total cost of the bridge came to 11 million Euros. On the date of this inauguration, this impressive bridge was the fifth biggest suspension bridge in the world and the largest outside the USA. Forty years on, it is still the 66th largest in the world.


Santa Clara Bridge, Coimbra
Over the centuries, several bridge have been built at similar locations across the river Mondego in Coimbra. The first was built at the order of King Afonso Henriques in 1132; four centuries later, King Manuel ordered another, and it is this latter bridge that can be seen in engravings and photograph. Demolished in 1873, plans for the present day construction, a metal bridge with lower deck, began in 1946. The new Santa Clara Bridge over Coimbra's river Mondego, an undisputed emblem of the city Coimbra, was inaugurated on 30th October, 1954.

Amiza de Bridge, Minho/Galicia
The new bridge over the river Minho, connecting Vila Nova de Cerveira and Goian in the Galician municipality of Tomino, was inaugurated in June 2004. Named the 'Ponte da Amizade' or Bridge of Frendship, it stands as a symbol of relations between the Poruguese and Spanish. Built of pre-stressed reinforced concrete and 430 metres long, it was the fulfilment of a dream long cherished by the local populations, complementing the road link between Minho and Galicia.

Moisteiro Bridge over the River Douro, Oporto
Anyone traveling along the banks of the river Douro in the Albufeira do Carrapatelo region of cruising along the Douro on a tourist boat cannot fail to be struck by the rare beauty of the Mosteiro Bridge. The elegance and lightness of its remarkable concrete structure made almost diaphanous by a fine concrete truss structure are accentuated by the curved deck that extends over the river supported at either end by the pillars of the old bridge. Built by Empresa Industrial do Norte, it was dynamited by the monarchists in 1919, restored in 1927 and rehabilitated by Estradas de Portugal (Portuguese Road Administration) in 2008.

Bridge over the River Arade, Portimao
Inaugurated on 12th September, 1991, the bridge over the river Arade is remarkable feat of engineering. A cable-stayed bridge with one central span and two side spans, it extends 842 metres, supported only at its two ends and suspended entirely from its towers. It is built totally of prestressed reinforced concrete and stays of steel strand. It plays a pivotal role in the economic development of the Arade estuary zone, revitalizing a geographic area of huge strategic and economic interest and a zone of unique beauty.

Iberian Bridges

Joint issue Portugal with Spain.

Of the 1215 kilometres of frontier separating Portugal and Spain, almost 400 - around one third - are marked out by extensive stretches of the rivers Minho, Douro. Tagus and Guadiana, all of which originate in Spain. Since immemorial time, these rivers have been the setting for both conflict and peace between the peoples on the two sides. Occupying a well-defined geographic macro-area - the Iberian Peninsula - the Portuguese and Spanish have a common history dating back many thousands of years. In the past, they lived united under one power for over one thousand years: first the Roman Empire (3rd century BC to 5th century AD), followed by the Suevi and Visigoths (6th and 7th centuries) and finally the Arab Empire (8th to 11th centuries).

  
The Alcantara Bridge (from the Arab Al-qantara, meaning "bridge"), designed by Gaius Julius Lacer, was built during the romanisation of Iberia in around 106 AD. Today, the history of this Iberian monument standing 61 metres high, 194 long and 8 wide, where the Alagon and Tagus rivers meet and as the latter enters its international section, is an eloquent testimony to centuries of Portuguese-Spanish relations.

  
Some nineteen hundred years later, the International Bridge over the river Guadiana connecting Vila Real de Santo Antonio in Portugal and Ayamonte in Spain was built. Inaugurated in 1991, this pre-stressed concrete cable-stayed bridge, with a 324 metres span, is a symbol of modern-day relations between the two countries, which since 1986 have been developing under the auspices of a larger and more powerful institution - the European Union.
