The Metsovitikos Bridge - designing a suspension bridge for the consequences of hazards

摘要

In 1998 Arup, supported by Wilkinson Eyre Architects, won an international competition for the design of a bridge to carry the proposed Egnatia Odos motorway across the valley of the Metsovitikos River, high in the Pindos Mountains of north-west Greece. The winning design was for a suspension bridge with a 550m long deck passing over the 145m deep vee-shaped river valley, shown in Pig 1. The structural form of the bridge was innovative in a number of ways most notably in that there were no towers, the main suspension cables being anchored directly into the sides of the valley. Also, the main cables and hangers were set in an inclined plane to enhance the architectural qualities of the bridge. The general arrangement of the bridge and the deck cross section is shown in Pig 2, 3 & 4.
