Ganter Bridge rises an astonishing 152.4 meters above the ground. The 160 meter long bridge designed by Menn. Built 1976-1980 over the Simplon Pass near Eisten, Switzerland, is a concrete cable-stayed road bridge.
The Ganter Bridge is hybrid cross of construction combining cantilever and cabling support system. Cantilever spands support the bridge's midsections which in turn are supported by cable stays embedded in prestressed concrete. The concrete walls protect the cables from stress and corrosion. Menn cleverly embedded the cable stays in prestressed concrete resulting in a bridge that appears to be a sculptured bird taking flight.
