Millau Viaduct description and facts:

The viaduct is located above the Tarn River valley in southern France, near the city of Millau.

Millau Viaduct is the highest bridge in the world, the bridge measuring 343 meters to the highest construction point exceeds by 19 meters the famous Eiffel Tower .

The bridge consists of 7 pillars with heights from 78 to 245 meters, while the height of the pylons is 87 meters. The pillars are connected by spans of 342 meters length (6 internal spans) and 204 meters (2 external spans).

Construction of the bridge lasted only 3 years, most of the construction elements were built on land, and then they were put on prepared places, for this purpose 64 hydraulic cylinders were used, which many days moved the spans at a rate of 9 meters per hour.

The prepared places are 4 holes for each of the pylons, 5-meter holes and 15 meters deep, with a special 3-5 meter-long tread at the base, ensure stability of the pylons.

At the moment when huge pillars stood in their places and the roadways were laid, construction and application of pylons began, which are separate structures in the shape of an inverted letter Y and do not constitute an extension pillars.

For the construction of the bridge, 85,000 were used. m3 of cement (about 206 thousand tons), and the weight of steel used at the construction site is 36 thousand. tonnes, which is five times the amount used for construction The Eiffel Tower . The total weight of the building is 290 thousand. ton.

At the peak moment, almost 600 employees took part in the construction, using the latest laser technologies, GPS, special asphalt and high-quality concrete and other innovative materials for their work. , all to control the construction of the centimeter.

The bridge is 32.05 meters wide and 4.2 meters thick, and has 2 lanes in each direction.

It is estimated that up to 50,000 vehicles pass through the viaduct per day (around 4,500 in winter), many local commuters due to costs chooses a different, free road.

The viaduct is located within the A75 motorway connecting Paris with the Mediterranean coast in the south of France. The cost of traveling the viaduct from January 2011 is respectively for a passenger car: 8.20 € in July and August and 6.40 € in low season, and for a truck 29.90 € throughout the year. The remaining 340 km of the A75 motorway is free.

At the time of completion, the bridge officially obtained three world records: 1) the highest pylon in the world (P2 with a height of 244.96 meters). 2) the highest tower of the bridge (the top of P2 lies at an altitude of 343 meters). 3) the highest bridge road in Europe (the road is located 270 meters above the Tarn River level).

The wiring of the viaduct consists of, among others, 30 kilometers of high voltage cables, 20 kilometers of fiber optics and 10 kilometers of low voltage cables. Employees have 357 telephone sockets at their disposal, which allow them to communicate with each other and between command posts located on masts.

The bridge is equipped with state-of-the-art sensors, such as anemometers, accelerometers, inclinometers and temperature sensors for measuring and detecting even the smallest movements of pillars, as well as measuring resistance for abrasion and tearing.

The toll point belonging to the viaduct is 4 km away from it, it has 8 lanes in each direction. The cost of building the facility with technical rooms, parking, control station and toilets was 20 million euros.

MILLAU wymawia sie jako 'MIJO', czyli Viaduc de Millau (wiadik demijo), jest na autostradzie A75 laczacej Clermont-Ferrand z Béziers 340km. Autostrada ta przebija sie przez francuski Masyw Centralny i w najwyzszym punkcie przechodzi przez przelecz Col des Issartets, 1121 m npm. Oprocz tego wiaduktu znajduje sie na niej jeszcze 6 innych wiaduktow, jeden most i 3 tunele.

Pracuję w transporcie międzynarodowym i przejeżdżałem tym wiaduktem w ciągu ostatniego roku kilka razy. W nocy, nad ranem, w dzień. Wrażenia niesamowite. W pobliżu wiaduktu znajduje się parking z punktem widokowym, gdzie można podziwiać wiadukt. Warto też ominąć wiadukt i krętą górską drogą zjechać do miejscowości Millau i podziwiać wiadukt z dołu. Zapraszam na www.planetg.pl, tam powinno być kilka moich zdjęć z wiaduktu.

Most to przeprawa nad wodą, a wiadukt nad drogą, doliną, wąwozem. Jeżeli przez dolinę lub wąwóz przepływa woda to jest wiaduktem. Wiadukt Millau przechodzi nad rzeką Tran. Czy Wiadukt Millau to most czy wiadukt? A może jest obojgiem, ale czy mamy dowolność w nazewnictwie? Czy konstrukcje takie to wiadukto-mosty? Chodzi mi o ścisłe określenie, bez zwyczajowego, tylko konstrukcyjne.
