World's Longest Pedestrian Bridge Opens in Switzerland

摘要

LONG BRIDGES do not necessarily have to be built across extensive bodies of water or deep chasms. The world's longest pedestrian bridge recently opened in Switzerland, and it covers a staggering 494 m across a tree-filled and rock-strewn mountainside that includes the Grabengufer ravine. In an unusual shape, the midpoint of the bridge is the lowest point of its arc, but that point is also its highest point above ground, 85 m above the floor of the ravine. However, the terrain traversed by the suspension crossing is so steep that although the mountaintop extends high above one side of the bridge, it descends sharply on the other side, offering monumental views of the Swiss Alps to those on the crossing.
