Blois (Loir et Cher). France. 1724. This stone bridge is built on the Loire river, for the “Route Nationale 10”, the only one bridge for long time in the City of Blois. It is 283 m long, comprising 11 spans, whose length varies from 16,55m to 26,30 m. This bridge is the first one of a series of bridges on the Loire River, using a new vault scaffolding technology (also applied for Cessart Bridge in Saumur). In Gabriel bridge, 2 intermediate columns are larger than the others, playing the role of local abutments. Several vaults were destroyed during wars, then reconstructed. Engineers: Jacques V Gabriel (First Engineer of the « Corps des Ponts et Chaussées », 1716), Jean Baptiste de Régemortes Picture : Georges Pilot Concorde Bridge. Paris. France. 1790. This road bridge on the Seine river is 137 m long, 16m large, enlarged until 35 m later on (1931). It comprises 5 circular arches, 20 to 23 m large. It represents the advanced concepts developed by Jean-Rodolphe Perronet in matter of stone bridges construction. Instead to consider that each pile must work as an arch abutment and must be stable by itself, all arches are built at the same time, using scaffoldings for all arches. This practice allowed to introduce a better lowering. It is to be noted that this bridge was built using stones from “La Bastille” jail. Engineer: Jean-Rodolphe Perronet (First Director of “Ecole Nationale des Ponts et Chaussées”, 1747) www.lcpc.fr Picture : Georges Pilot Trizolos Bridge. 19th Century. Greece. It is an one span masonry arch bridge. Its span is about 30m long 15m high. The width of the deck is about 2.00 m and 0.80m thick. The bridge is founded on solid rock. It is a representative masonry arch bridge. Its structural form was very popular that period. We also know from the history, that this type of masonry arch bridges were constructed by a group of technicians that were specialized and had a lot of advantages in the local societies.

(Hérault), France. 1810. www.planete-tp.com This elegant road bridge is built on the Hérault River. It is representative of the “Languedoc School of stone bridges” leaded by B. Garipuy. It is 174,76 m long, comprising 3 stone arches respectively 25,97 , 50,72 and 25,97 m long. One of the main problems was the construction of the foundations, protected by clay cofferdams. This bridge location was used long time ago for road traffic, at the Roman period, then, later on as part of the Royal Montpellier-Paris Road. Engineers: Bertrand Garipuy and Bertrand Garipuy Junior, www.struturae.de ° http://perso.wanadoo.fr/laure.gigou Picture : Nicolas Janberg ° Pont de Pierre. Bordeaux (Gironde). France. 1822. This bridge supports the important National Road 10, from Paris to Bordeaux, on the way to Spain: then it was considered for a long time as one of the most important bridges in France. It is 487m long, built with 17 spans with an circular arc profile. The structure is in stone and the facing in bricks. As a point of recent industrial event, it is to be noted that this bridge should have been an obstacle for transfer, by boat, of fuselage elements of the Airbus A 380 aircraft. Special boats are used for that…at low level tide!

This railroad arch bridge is a stone bridge, 89 m long, included the main span, 47m long. It is a typical work designed following Paul Séjourné concepts: the weight of stone bridges is reduced when using minor arches constructed each side of the main arch. Sejourné concepts for stone bridges mark the peak for this style of construction in France. Engineer: Paul Séjourné www.planete.com° Photo : Marcel Prade ° Fontpédrouse Bridge. (Pyrénées Orientales). France. 1908. This spectacular bridge is one of the most remarkable works on the railways line “Le train jaune” (always under function) running between Villeneuve-de-Conflent and La Tour de Carol.

Georges Pilot. October 2007 Synthesis of bridges Steel bridges in Europe (1/9) The Forth Railway Bridge.United Kingdom. 1890 The need for the bridge was a result of a quest by the railways for a shorter route to the north. At the location of the bridge at Queensferry the Forth narrows to a channel little more than a mile wide, which is divided into two by the island of Inchgarvie. The superstructure of the bridge is basically three towers with cantilever arms on each side. The towers are 330ft high above the granite pier foundations, and the cantilever arms are each 680ft long, projecting outwards from the towers. The ends of the cantilevers over the river are linked by suspended spans of 350ft. Clearance for shipping is 150ft above high water. The overall length of the bridge is 8,296ft, including main spans1,710ft, using 54,160 tons of steel. Engineers: Sir John Fowler and Benjamin Baker Contractor: Tancred, Arrol & Co ( William Arrol) „Blaues Wunder“ bridge, Dresden. Germany. 1893 It is a cantilever truss bridge, with three hinges, in wrough iron/steel (?). The 270.2 m long bridge with a main span of 146.7 m crosses the Elbe without supports between the Loschwitz and Blasewitz districts. It was built 1891 –93 to designs by bridge builder Claus Köpcke as a “rigid suspension bridge”. It was dubbed the “blue wonder” because of its striking design and the blue colour it adopted after the “chrome yellow” pigment in the bridge`s green paint gradually. Architect: Claus Köpcke www.dresden-blaues-wunder-de Photograph: Michael Fehlauer, Köln, 2005 Cernavodă Bridge. Romania. 1895. Was the longest bridge in continental Europe at that time. 5200 tons of soft steel were used for the superstructure and 113 tons of hard steel for the supports, and for the foundations – 1136 tons of steel for the caissons and 42000 m3 of brickwork. The total length of the bridge is of 4088 m between the left bank and the right one of the Danube valley. Applying of Saligny’s inventions were the novelties in this field: the new system of console girders for the bridge superstructure and the use of the soft steel instead of the puddled iron as building material for bridge floors. Between 1970 and 1980, a second bridge was built, in parallel with the existing one, for a dual railway and a motorway.

France. 1900 This steel bridge was constructed on the Seine river for the “Exposition Universelle” (World Fair) organised in Paris in 1900. It is 140 m long and 40 m large, including an arch 109 m long, comprising 15 parallel arcs with 3 hinges. Its lowering, 1/17, was remarkable at this period. At the time of construction, a very innovative construction process was used: the steel segments were smelted and moulded in a factory (located in Le Creusot), then elements were bolted in situ. This bridge shows very rich decorations which makes it one of the most famous in Paris. It is listed as an historical monument Engineers: Jean Résal and M. d’Alby www.lcpc.fr Picture : Georges Pilot Le Viaur viaduct, Carmaux (Tarn). France. 1902 This bridge was built on the Viaur river, as a part of the railway line Carmaux-Rodez, constructed for the regional development: the Carmaux basin was an important region for coal production. It is 410 m long, with a very remarkable 220 m long central span (Garabit bridge central span is “only” 165 m long). Side spans are 95 m long. It is a cantilever bridge comprising an articulation in the middle of the main span. This bridge is register at the survey of the French Ministry of Culture.

It is located at the end, on Lyon side, of this precursor line which belongs to the “Saint-Etienne” network. Engineer: Maurice Koechlin www.structurae.de ° Document : Jacques Mossot ° Lowicz bridge. Poland. 1929 It is the first welded steel road bridge in the world. The superstructure consists of two truss girders of 27 m span with steel deck. Welded truss joints shape was adopted from riveting technology. Bridge deck was also welded. The steel is a Iow-carbon steel of 370-420 MPa in strength with allowable stresses of 98,1 MPa for girders and 81,5 MPa for deck. The structural elements were manufactured in workshop and assembled at site by „K. Rudzki i S-ka" Company in collaboration with „Soudure Electrique Autogène" from Brussels. In 1977 it was replaced by a new one. The old superstructure was moved 25 m upstream the Sludia river for preservation as a monument of bridge technique. Engineer: Pr Stefan Bryla.

Croatia. 1939 This bridge in Zagreb in Zagreb is technically one of the most important structures ever to be built in Croatia. The 9 m wide superstructure is supported on stone piers of the older bridge dating back to 1892. The bridge has four continuous spans, approximately 55 m long. The structure consists in 2 plate girders with very thick flanches made of poor quality steels, and reinforced concrete deck. The fact that the welding of thick flanches was carried out superbly received a lot of attention worldwide. On-site testing upon bridge completion showed that the composite action o of the concrete deck and steel structure was achieved. It is an important contribution to the development of civil engineering structures in general. Engineers: M. Frkovic, J. Erega The Green bridge with sculptures. Lithuania. 1894/1952 It is known that the first wooden bridge was built around 1536. In 1739 the Great Duchy’s of Lithuania treasurer Solohub built wooden bridge that was painted in green therefore people began to call it The Green Bridge. In 1894 local authority decided to build metal bridge. In 1944 the metal bridge was destroyed. The contemporary bridge was finished around 1952. In 1975-1978 The Green Bridge was repaired. Length of the bridge – 102,9 m. Width – 24 m.

Main build of the bridge – 4 steel cross-sectioned riveted beams which span 17,40 m long cut. Width – 8,4 m. As it was Bernardinu church and Bernardine abbeys for men and women by the bridge, bridge was named Bernardinu bridge. The contemporary bridge was finished around 1880. Around 1956 the bridge was reconstructed. Engineer of the contemporary bridge: Levikis (1880) Sloboda bridge. Croatia. 1959 The Sloboda (freedom) bridge is the central bridge in Zagreb, which helped spreading of the city to the Sava river right bank. Special attention was given to aesthetically pleasing structure, also to devise solutions that would prove adequate to accommodate traffic in the decades to come The overall length of the bridge is 806 m, consisting in two 135 m approach viaducts, two large abutments, of 71 m and 62 m in length, and the main 373 m long bridge structure. The central span bridging the Sava river is a two-rib steel arch structure, It spans 100 m with a rise of only 7,36 m, and has a maximum depth at springings of 1,30 m (1/87 of arch span). To support the arch thrust large bocks os concrete were constructed and founded on caissons. Designer: K. Tonkovic Caronte Bridge. Martigues (Bouches du Rhône). France. 1972. Caronte Bridge is a highway bridge which crosses the Caronte canal, close to Martigues city, in the vicinity of Marseille. It is a steel portal bridge, 875 m long, including a 300 m long main span.

The viaduct Sfalassa connects the two sides of the Sfalassa cliff along the motorway A3 Salerno-Reggio Calabria. It is the longest metal frame bridge ever built. Completed in 1973, it is 893 meters long, 253 high from the valley floor, and has a 360 meters span between its hinges. The frame is divided into three spans (110 + 156 + 110 meters) Designer/Engineer: Silvano Zorzi Bridge over the river Piave in Caralte. Belluno (Veneto). Italy. 1981. The bridge across the Piave River is part of what is today generally called the Cadore Viaduct, which is composed by three viaducts and an orthotropic beamed arch type bridge with a 272 meters long span and deck divided into three spans 72, 128 and 72 meters long respectively. The height from the valley floor is 200 meters. Beyond the structural concept, the uniqueness of this project design was its assembling. Only four big manoeuvres were carried out, reducing the bridge active joints to only three, one on the two legs and one in the middle of the span.

Turkey. 1998 Atatürk Viaduct crosses over Olucak Valley on TAG (Tarsus-Adana-Gaziantep) Highway, an important section of TEM (Trans European Motor Ways). One of the most important innovations developed in the TAG Highway is steel viaducts with long spans. A special type of structural steel named as ventilated steel was used which provides protection against corrosion by preserving a protective rust layer without any need of painting. The total length is 801.50 m. with maximum span length of 110 m. and the height is 149.50m. It comprises two edge pedestals, seven mid pedestals, and eight apertures and constructed as Korten steel box sections with composite slab due to inconvenient topographic conditions. Atatürk Viaduct was the second biggest viaduct of Europe and the first of Turkey at time of construction. Manavgat bridge. Turkey. 1999. Manavgat Bridge is located on Manavgat Creek at the new section of Antalya-Alanya highway. Settlements due to weight of soil fill at the approach zones of the bridge on both edges were found to be within tolerable limits upon soil investigations. However necessary precautions were taken during the construction period. Manavgat Bridge is the first application in Turkey of long orthotropic slab. Total length of three spans is 170 m, mid span being 80 m and each one of the two side spans is 45 m. The system is designed and constructed as twin-slab each of which is 13.60 m wide, and its total width is 27.20 m. Bridge cross section is composed of a 6 meter width box section and 3.80 m cantilevers on both sides, in the transverse direction of bridge axes. Solférino Footbridge. Paris. France. 1999.

The headline: "The shores of the Bosphorus linked by wire." Then in April the technical staff crossed the service bridge built on the guide wires. Another striking headline was “The first to go from a continent to another one, from Europe to Asia, at foot”. The Bosphorus Bridge was officially opened by President Fahri Korutürk during the 50th anniversary celebrations of the foundation of the Republic, in 1973. 28 thousand 126 vehicles crossed it within the first 24 hours.

United Kingdom. 1981 This superb modern suspension bridge was, at the time, the longest span of any bridge in the world. The main span of 1,410 m and the asymmetric north and south side spans of 280m and 530 m respectively are suspended from hollow reinforced concrete towers that reach 155.5m above the tops of their piers, the first major suspension bridge to use concrete in this way. Each 700m diameter, 5,500 tonne suspension cables consists of 37 strands, each strand having 404 individual 5mm high tensile steel wires. The welded steel deck structure is 28.5m wide overall and 4.5m deep and is suspended from the main cables by inclined hangers.

This bridge is part of the railways line (always active) built until 1910 from Villefranche-de-Conflent to La-Tour-de Carol, named “Le train jaune”. It involves a new concept for the cables, making them able to support heaviest loads than normal suspension brides. This concept was developed by Major Albert Gisclard, from the French Corp of Engineers: it is a step towards cable-stayed bridges.. The licence of this new concept was delivered to F. Arnodin, then used for reinforcement of several suspension bridges. Engineer: Albert Gisclard. www.tramwaytetg.free.fr/page16.htm ° Picture : L. Maraval ° Lézardrieux bridge. (Cotes d’Armor).

The Rion-Antirion bridge span over the Corinth Gulf and is a part of the western transportation axis of Greece. It was for more than 120 years the vision of many governments. Its construction was very difficult due to the strong seismic activity of this area (there is an active seismic fault in the Corinth Gulf) as well as the absence of a stiff seabed subsoil. The project started at 1998 and finished at 2004. The bridge consists of 2252 m long 4 pylon cable-stayed and the three inner spans are 560m long. There are two approach viaducts of 392 and 239 m at both sides. The three pylon foundations have about 90 m diameter.The bridge is the longest cable stayed bridge in the world at this time.
