Facts and History of Millau Bridge. Here are a few vital stats of the bridge: Length: 2500 m Width: 32.05 m Clearance below: 270 m Max height above ground: 342 m … After starting on the northern side, they crossed the viaduct, then retraced their steps. Depending on their length, the cable stays were made of 55 to 91 high tensile steel cables, or strands, themselves formed of seven strands of steel (a central strand with six intertwined strands). [citation needed], The steel road deck, and the hydraulic action of the road deck were designed by the Walloon engineering firm Greisch from Liège, Belgium,[16] also an information and communication technologies (ICT) company of the Walloon Region. I wasn't entirely sure what to expect from the World's Tallest Bridge, but it blew my tiny mind anyway. Management was handled by Eiffage Concessions. This Viaduct of (1,125 feet [343 meters]) opened in 2004, at the time it was the tallest cable-stayed road bridge in the world. In January 1995, the government issued a declaration of public interest to solicit design approaches for a competition. The construction of Millau Viaduct began in late 2001. His debut self help book "Happiness Decoded" was released in early 2014. We should consider floodlighting the limestone ridge at night, creating a son et lumiere when the bridge is lit up. Designed by the French structural engineer Michel Virlogeux and British architect Norman Foster, it is the tallest bridge in the world with one mast's summit at 343.0 metres (1,125 ft) above the base of the structure. The total cost was €20 million. Millau Viaduct has a deck height of 270 m (886 ft) and ranks 15 in the list of highest bridges in the world. where there any fatal incident during the construction stage of the project or not? Displacements of the deck on the abutment level are measured to the nearest millimetre. The Baluarte Bridge is much shorter than the Viaduc de Millau, only spanning 1,124 m (3,688 ft) in total, with the cable-stayed section being 520 m (1,710 ft) long. [citation needed], The rest area of Brocuéjouls, named Aire du Viaduc de Millau,[24] is situated just north of the viaduct, and is centred on an old farm building named 'Ferme de Brocuéjouls'. 14 December 2001: laying of the first stone, March 2002: start of work on the pier support C8, June 2002: support C8 completed, start of work on piers, July 2002: start of work on the foundations of temporary, height adjustable roadway supports, August 2002: start of work on pier support C0, September 2002: assembly of roadway begins, 25–26 February 2003: laying of first pieces of roadway, November 2003: completion of the last piers (piers P2 at 245 metres (804 ft) and P3 at 221 metres (725 ft) are the highest piers in the world), 28 May 2004: the pieces of roadway are several centimetres apart, their juncture to be accomplished within two weeks, 2nd half of 2004: installation of the pylons and shrouds, removal of the temporary roadway supports, 16 December 2004: opening of the viaduct, ahead of schedule, 10 January 2005: initial planned opening date, The highest pylons in the world: pylons P2 and P3, 244.96 metres (803 ft 8 in) and 221.05 metres (725 ft 3 in) in height respectively, broke the French record previously held by the. The farm and its surroundings can accommodate entertainment and tourism promotion activities.[26]. 343 m (1,125 ft): height of Pier 2, the tallest (245 m or 804 ft at the roadway’s level) 270 m (886 ft): average height of the roadway. The objective of the viaduct would not be achieved; because of the toll, the viaduct would be little used, and the project would not solve Millau's congestion problems. Bridges are often considered to belong to the realm of the engineer rather than that of the architect. The pillars had to be exactly in place for the bridge to be a success and signals from multiple satellites were used to pin point the position. The decision to construct the bridge was made in October 1991. The wedges were hydraulically operated, and moved repeatedly in the following sequence: (1) the lower wedge slides under the upper wedge, raising it to the roadway above, and then forcing the upper wedge still higher to lift the roadway; (2) Both wedges move forward together, advancing the roadway a short distance; (3) The lower wedge retracts from under the upper wedge, lowering the roadway and allowing the upper wedge to drop away from the roadway; the lower wedge then moves back all the way to its starting position. [citation needed], Detailed studies were carried out by the successful consortium, steered by the highways authority until mid-1998. if yes how many? It is situated in south France near the Millau town. When the details were eventually finalised, the whole design was approved in late 1998. [22], Each of the seven pylons[4] is supported by four deep shafts, 15 metres (49 ft) deep and 5 metres (16 ft) in diameter. The concept and design for the bridge was devised by French designer and structural engineer Dr Michel Virlogeux. [18], The sliding shutter technology for the bridge piers came from PERI. You could also do it yourself at any point in time. It cost us 12.90€ to cross in a motorhome (I believe it's more expensive in July & … Additionally, two piezoelectric sensors gather traffic data: weight of vehicles, average speed, density of the flow of traffic, etc. The launching advanced the road deck at 600 millimetres (24 in) per cycle which was roughly four minutes long. No other high bridge in history caught the eye of the media more than the opening of the Millau Viaduct in 2004. It cost up to €394 million. The upper and lower wedge of each pair pointed in opposite directions. Length: 2,460 m (8,071 ft) Width: 32 m (105 ft) Maximum height: 343 m (1,125 ft), or 19 m higher than the Eiffel Tower Slope: 3.025 %, going up from north to south in the direction Clermont-Ferrand – Béziers Curve: 20 km (12.4 miles) Height of the tallest pier (P2): 245 m (804 ft) Height of the pylons: 87 m (285 ft) Number of piers: 7 Length of the spans: Two end spans of 204 m (669 ft) each and six central spans of 342 m (1,122 ft) each. [citation needed], The only other business that had a notable role on the building site was Freyssinet, a subsidiary of the Vinci Group specialising in prestressing. The 2,000 cubic metres (2,600 cu yd) of concrete necessary for the treads was poured at the same time. It comprises eight spans. Société du Viaduc de Millau, including the French companies ASF, Egis Projects, GTM Construction, a consortium led by Générale Routière, with Via GTI (France) and. Millau viaduct holds the world record for the tallest bridge, culminating at 343 metres (higher than the Eiffel tower), 2460 metres long and touching the bottom of the Tarn valley in only 9 places. The two popular types of cable-stayed bridge designs are harp and fan. In a cable stayed bridge, multiple cables from each pillar are transmitted to support a section of the bridge deck around the pillar. Millau Viaduct. Opponents advanced several arguments:[citation needed], Two weeks after the laying of the first stone on December 14, 2001, the workers started digging the deep shafts.
