Abstract
Over Arup (1895-1988) once said in a BBC interview that the two structures that had given him most satisfaction were the Highpoint flats in North London (1935) and the Kingsgate footbridge, Durham, Yorkshire (1963), as “both are rather perfect examples of the complete integration of architecture, structure and method of construction”.

Abstract
The Jylland (Jutland) peninsula and the approximately 278 islands that form Denmark have had bridge connections since the Middle Ages. The most notable bridges of the 20th century are the high level bridges such as the Lillebælt Bridge from 1935 and the Storstrøm Bridge from 1937. Cable supported bridges and cable-stayed bridges have been making up the most significant infrastructural aspects which cross the seaways of the Baltic Sea.

Abstract
In Japan where many earthquakes occur there is a certain standpoint about long–life architecture and bridges The relation between material and form is important for this standpoint. The reason is not only that materials have their own character, for example, physical and chemical properties, but also that form has its own individual character as load–bearing system. Without the relation between material and form, long–life architecture and bridges can’t be realized.

Abstract
After the earthquake of 1923 which devastated Tokyo, Japanese engineers worked on reconstruction to generate a new Modern landscape in the capital, taking into account various arguments ranging from science to culture. The construction process of the Eïtai and Kiyosu bridges over the Sumida River are indicative of this development. This paper will describe this process to better understand Japanese bridge design in 1920s in terms of technology and aesthetics.

Abstract
The heart of the famous Düsseldorf Bridge Family are the three cable-stayed bridges built between the late 50s and early 70s of the last century. They mark the beginning of the development of Modern cable-stayed bridges, but not only from a technological point of view. Instead they develop the aesthetical potential once the new structural type has become favorable all over the world.

Abstract
Sergio Musmeci occupies a very important position in the history of late 20th century Italian engineering. Born in Rome in 1926, he initially graduated in civil engineering and later in aeronautical engineering. Following an apprenticeship with Pier Luigi Nervi, in whose office he worked from 1949 to 1951, and with Riccardo Morandi, he later opened his own engineering and architecture office together with his wife, the architect Zenaide Zanini. He taught at the University of Rome, initially as an assistant to the course in Rational Mechanics and Graphic Statics, and later as professor of Bridges and Large Structures.

Abstract
Eduardo Torroja Miret graduated as an engineer in 1923. That same year, after a bloodless coup d’état, General Primo de Rivera assumed the control of government in Spain and launched a modernizing economic program clearly based on infrastructure: development of the telephone network, modernization of ports, tramway system expansion, creation of 800 km of railroads, extension and paving of over 15,000 km of roads...

Abstract
From 1904, when his career began, until 1962, when he died, Eugène Freyssinet did not stop building or advising on all aspects related with his work. To give an idea of his interest in the field of bridges, we selected the following: the Veurdre and Plougastel bridges as reinforced concrete examples and the Luzancy, the Marne and the Caracas La Guaira highway bridges as prestressed concrete works. In these brief descriptions, rather than the technical nature of the design, we have focused on intuition and innovation which made these works models and which inspired many engineers to continue working respecting quality.

Abstract
The General Rafael Urdaneta Bridge spanning over Lake Maracaibo in Venezuela (1958–1962), designed by Ing. Professor Riccardo Morandi, a masterpiece of Modern engineering, is now a Modern Landmark at Risk. The remarkable and little known story of the construction of this structure “could not be accomplished by a handful of men. From planning to financing, from design to construction, a great number of Venezuelan and European engineers worked jointly in Wiesbaden, Caracas, Rome, Maracaibo, Zürich, Paris, and Lisbon. In this way, one of the most outstanding structures of our time was erected within the stipulated - and brief construction time.”

Abstract
Robert Maillart’s innovative views concerning the use of concrete come within the scope of the history of structures, structural materials and concrete as a material of structure. It will even lead us far beyond these issues. At the end, the point of view expressed in this article will be the view of a structural designer. When preparing this reflection, I realise that there is no straightforward answer to the question: “What is in fact Maillart’s real innovation considering all the contributions he made to the art of engineering?” Putting forward the different aspects mentioned above as an introduction seems to be a more relevant way to find a contemporary answer taking time and context into account. Consequently the first part of this text is a general presentation of Maillart’s works. Following we will make a detour to make what I, and many others, consider to be the most revolutionary aspects of Maillart’s practice fully comprehensible. So starting from the historical development of reinforced concrete as a structural material, we will move to the contemporary context to figure out how the intrinsic structural complexity of concrete is managed today. We will see that some difficulties emerge from the behaviour of concrete in relation to the classic theories of mechanics. If some Modern theories find an answer to the problem, it will become obvious that Maillart had already found a convincing way of dealing with these difficulties. We will then return to Maillart’s works to answer the question through the status he was to give concrete when it came to structural design and the methods he used to achieve his objectives. I hope this will lead us to consider Maillart’s approach as one of the most visionary ever devised.
