The walkway is one meter (3 feet and 3 inches) in width, and rises over
100 meters (350 feet) above the river below. It is currently in a highly
deteriorated state and there are numerous sections where part of or the
entire concrete top has collapsed away. The result is large open air
gaps that are bridged only by narrow steel beams or other support
fixtures. Very few of the original handrails exist but a Via ferrata
safety-wire runs the length of the path. Several people have lost their
lives on the walkway in recent years and after two fatal accidents in
1999 and 2000,[2] the local government closed both entrances.
