Europa - Bridges

 The first stamp features Megyeri Bridge, which is 1,861 metres long and is Hungary’s second-longest bridge and the longest bridge over a river in the country. Horizontally, the bridge is composed of five dilation sections: two end parts, which stand in flood areas, the central section on Szentendre Island, and two other parts which span the main branch of the Danube and the Szentendre branch of the Danube. The 600-metre-long structure with a 300-metre central opening over the main branch of the Danube is the first cable-stayed bridge in Hungary and its 100-metre tall pylons form large letter “A”s. On one leg of the pylon, there are stairs and on the other a lift. The bridge was built as part of the northern sector of the M0 ring motorway around Budapest between 2006 and 2008. The outstanding engineering achievement is a worthy member of the family of bridges over the Danube.

The other stamp presents Kőröshegy Valley Bridge, which is 1,872 metres long. This is currently Hungary’s longest bridge and is located on the section of the M7 motorway running along Lake Balaton near Kőröshegy and Balatonföldvár. The 17-arched, pre-stressed monolithic concrete structure was built between 2004 and 2007. The span between the pillars is 120 metres and the tallest pillar is 80 metres high. There are stairs in every pillar and a lift in two of them to facilitate inspecting the bridge. As a result of a 3% incline, there is a 53-metre difference in height between the two ends of the bridge. Taking account of environmental considerations, all the rainwater from the bridge is collected and treated in several stages before being allowed back into the natural surroundings. It is a unique and remarkably impressive feat of civil engineering.

Grand Opening of Pelješac Bridge

 The Pelješac Bridge is a part of the national road which goes around the Neum Corridor. It is a part of the project called "Road Connection with Southern Dalmatia". The project includes the construction of the bridge, access roads to the bridge as well as the Ston bypass, which has enabled the establishment of a strong road connection between the separated parts of the land territory of the Republic of Croatia. The 32.5 kilometers long two-lane state road connects the far south and is an essential prerequisite for the development of the mainland and islands of the Dubrovnik area. The 2404 meters long Pelješac Bridge is the most challenging part of the project and it crosses a sea strait – the Mali Ston Channel. The project "Road Connection with Southern Dalmatia" is a strategic interest of the Republic of Croatia. It is also located on one of the European transport corridors, therefore it has been largely financed from EU funds.


The width of the sea channel at the bridge site is 2140 meters, and the average sea depth is 27 meters. A waterway passes through the bay, which is protected as a special nature reserve: the designated navigation passage is 200 meters wide and 55 meters tall. The foundation soil, which consists of deep silt and clay deposits above a rock layer, was a challenge to the designers, as were the seismicity of the location and a significant likelihood of strong winds. The task of bridging the sea channel in such complex circumstances was achieved through a unique construction consisting of a suspension bridge with six pylons and five main openings measuring 285 meters each, on deep foundations built on driven piles.

There is a total of 13 openings with start and end support on bridge abutments and a total of 12 in-between support elements. The concept of a bridge without a pronounced central span, symmetrical and with no extremely tall pylon verticals, with a series of identical spans over the central part of the channel and with clearly defined, repetitive elements of pillars, girders, and stay cables was adopted. The construction of the bridge started in mid-2018 and ended in early 2022. The investor of the entire project was Hrvatske ceste, a Croatian company for the management, construction, and maintenance of state roads, while the main contractor was the Chinese company China Road and Bridge Corporation, alongside which numerous Croatian companies and individuals worked on the project.

Europa - Bridges

At the beginning of the 18th century, after the end of the War of the Spanish Succession and the war against the Ottoman Empire, the conditions to revive the economy and trading in the area of Croatia were met creating a need to connect Pannonia with the coastal area by a road through the mountainous area of Gorski kotar. In 1718, the Croatian Parliament approved the proposal to build a road from Karlovac through Novigrad na Dobri, Delnice, and Javornik to the port in Kraljevica. However, the construction started a while later, in 1725, and was fully completed in 1738. The designer and builder of the road named Via Carolina Augusta, today known as Karolinska cesta, was Matija Antun Weiss (1661 – 1738). The road was named after the ruling emperor, Charles IV, who personally traveled the passable section of the route in 1728. The road is around 60 miles or roughly 106 km long and the planned costs were 70,000 forints. In order to cross over certain streams and rivers, several bridges had to be built on the road, typically wooden constructions on stone columns and abutments.

Among the bridges on the River Dobra, the bridge near Novigrad na Dobri especially stands out. It was built using cut stone. The bridge is located in a tame valley of the river not too far from a castle built on a hill at the beginning of the 16th century. It was owned by the Frankopan, Zrinski, and Patačić families. According to some accounts regarding bridge tolls, there was a wooden bridge prior to this one in the same location.

The bridge is 114.5 m long, and 5.8 m wide and it crosses the river with 10 semi-circular arches with a span of 4.9 m. The columns are massive and harmoniously shaped with pronounced extents. The fences are made of stone, 0.5 m wide and 0.6 to 0.75 m high. The bridge grade level is convex with the highest point in the middle of the bridge. In terms of the layout, the bridge is perpendicular to the river flow. It is an interesting fact that, according to some accounts, the owners of the castle and the surrounding properties had to finance the bridge construction even though the road was financed by the Viennese court.

The bridge is a valuable monument to the bridge building skill and it is in relatively good condition considering that it is more than 250 years old and a protected cultural monument.

The bridge on the River Dobra can be reached from an exit on the Zagreb – Rijeka Highway 1 at the Novigrad junction and then by a local road leading to Novigrad na Dobri. 


The Franjo Tuđman Bridge (Croatian: Most dr. Franje Tuđmana) is a cable-stayed bridge carrying the D8 state road at the western approach to Dubrovnik, Croatia across Rijeka Dubrovačka near Port of Gruž. The original bridge design was developed in 1989; however, construction was stopped at the onset of the Croatian War of Independence. Named after the 1st President of Croatia Franjo Tuđman, the bridge has been redesigned by the Structures Department of the University of Zagreb.

The bridge is 518-meter (1,699 ft) long, measured between the abutments. The substructure of the bridge consists of abutments, a pier on the western shore supporting a pretensioned girder, and an anchoring pier on the eastern shore.

The supported structure on the cable-stayed portion of the bridge consists of a composite girder, an A-shaped pylon, and the cable-stays. The overall span of the girder is 324.7 m (1,065 ft). Concrete roadway slab is of the generally constant depth of 25 cm (10 in). A total of 38 cable stays have been executed, comprising 27 to 61 steel wire cables placed in protective polyethylene pipes.

The pylon is 141.5 m (464 ft) tall, measured from the top surface of the foundations. It comprises a box cross-section of varying sizes. An additional box girder is executed just below the suspended structure providing it additional support as well as bracing the pylon legs. The cable stays are anchored to the top of the pylon. A special opening has been executed in one of the pylon legs, next to the sidewalk, providing access to the inside of its cross-section, where there are rungs facilitating climbing to the top of the pylon, where another opening on its top allows replacements of the anchors, should that become necessary.

The western part of the bridge comprises a pretensioned girder of variable depth 3.25 m (10.7 ft) at the abutment, 8.22 m (27.0 ft) at the pier, and 3.2 m (10 ft) at the end of the cantilever.

Construction of the bridge started in October 1998. The construction works were carried out by Walter Bau AG and Konstruktor, Split. Construction was completed in April 2002, and the bridge was officially opened on May 21, 2002. The bridge construction costs were reportedly 252 million Croatian kuna (c. US$31 million) making Franjo Tuđman Bridge the most expensive bridge in Croatia.

Oresund Bridge

The Øresund or Öresund Bridge is a combined two-track rail and four-lane road bridge-tunnel across the Öresund strait. It is the longest combined road and rail bridge in Europe and connects the two metropolitan areas of the Öresund Region: the Danish capital of Copenhagen and the Swedish city of Malmö. The international European route E20 runs across the bridge and through the tunnel via the two lane motorway, as does the Öresund Railway Line. The construction of the Great Belt Fixed Link and the Øresund have connected mainland Europe to Sweden and the rest of Scandinavia. The bridge was designed by the Danish architectural practice Dissing+Weitling.




The reason for incurring the additional cost and complexity of building a tunnel instead of another section of bridge is to avoid obstructing aircraft from nearby Copenhagen Airport and to provide a clear path for shipping. The bridge crosses the border between Denmark and Sweden, but due to the Schengen Agreement and the Nordic Passport Union there are no passport controls. There are frequent customs checks at the toll booths for those entering Sweden but not for those entering Denmark.

Sunshine Skyway Bridge

The U.S. Postal Service recognized the 25th anniversary of Florida's Sunshine Skyway Bridge by issuing the $5.15 Sunshine Skyway Bridge Priority Mail stamp. In the stamp artwork, the bridge rises from Tampa Bay's vivid blue water and is silhouetted against an orange sky. Tiny vehicles on the roadbed reveal the massive scale of this engineering marvel.


The new Sunshine Skyway bridge started with a disaster and concluded with the world's most beautiful bridge. The collision and loss of life which occurred on May 9, 1980, created an opportunity to build a new bridge which memorialized the 35 people who lost their lives that day; engaged state of the art design, engineering and construction and unified the Tampa Bay communities to create what is now the signature of Tampa Bay.

Construction began on the new bridge began two years after the tragedy. The new bridge featured on the stamp is one of the first major concrete-and-steel, cable-stayed bridges in the United States. Completed in 1987, the main bridge and approach spans stretch more than four miles across Tampa Bay and link the Gulf Coast communities surrounding St. Petersburg and Bradenton.

To many people the 42 brilliant yellow cables look like sails and their two supporting pylons like masts rising from the water. Engineers designed the cable-stayed section of the new bridge to soar 190 feet above the water to allow unhindered navigation to and from the busy port of Tampa.

Setting new standards for technical innovation and esthetics, the structural design is considered by many to be a modern masterpiece. Renamed in 2005 after the former governor who envisioned its construction, the Bob Graham/Sunshine Skyway Bridge has been the recipient of dozens of engineering and design awards.

The stamp, designed by Carl T. Hermann of North Las Vegas, NV, showcases a digital illustration created by artist Dan Cosgrove of Chicago, IL.

Technical Monuments - Cable-stayed bridge in Ústí nad Labem


Cable-stayed bridge - Mariánský Bridge in Ústí nad Labem, designed by the renowned architecture studio Roman Koucký, is one of the most distinctive and disputed projects built in the post-November 1989 Czech Republic. Following years of lengthy discussions about the location of the bridge, the city councilors decided to place it under the Mariánská Rock, a site best suited for the bridge's main role, i.e. combining the city's three quarters - the city center, Krásné Březno on the left bank and Střekov on the right bank of the Labe river. The 70m high bridge was built from 1993 to 1998 and became the city's new dominant. The height is not the only feature attracting the attention of people: the impossible-to-overlook system of steel cables suspending the 170m long bridge is similarly provoking. The architect designed the number of cables, and the height and shape of the pylon not only with respect to static but also to his artistic visions. For instance, the height of the pylon was to counterbalance the Mariánská Rock on the other side of the river. It also matches the height of the tower of the gothic church of the Assumption of the Virgin Mary nearby.


According to the Structural Engineering International (SEI), Quarterly Journal of the International Association for Bridge and Structural Engineering (IABSE), it is one of the ten most beautiful 1990s world buildings. It has also become the most expensive local project in the area of transport infrastructure since 1948, financed by a city. The city had to postpone the project of reconstruction of Mírové Square and other projects. Last year the bridge changed its owners: it has become the property of the Road and Motorway Directorate of the Czech Republic since June 26th, 2008.
