Wilkinson Eyre: Viaduc de la Savoureuse, France.As part of the planned Rhine-Rhone (Dijon-Mulhouse) high-speed rail High-speed rail is a type of passenger rail transport that operates significantly faster than the normal speed of rail traffic. Specific definitions include 200-320 km/h (125-200 mph) - depending on whether the track is upgraded or new - by the European Union and above 90 mph link, Wilkinson Eyre were the winners of a design competition for this 850m long viaduct viaduct (vī`ədŭkt') [Lat.,=road conveyor], type of bridge for carrying a highway or railroad over a valley, over low ground, or over a road. between Montbeliard and Belfort. Their proposals extend over a 1300m long site, including the consideration of significant earthworks earthworks: see land art. , cuttings and associated landscaping. The structure spans between distinctive tetrapod tetrapod a four-limbed, vertebrate animal, i.e. all vertebrates except fish. Compare with quadruped. piles that were designed--in collaboration with engineer Jean Muller International--to cope with the significant structural implications of the passing trains that will travel at speeds of up to 220mph. These double V-shaped elements bear onto tapered concrete pads that account for changes in the natural ground level across the valley. R. G.
