In Lichterfeld Germany you can visit this conveyor bridge that was formerly used in the opencast lignite mine Klettwitz-nord. This gigantic steel bridge was build between 1989 and 1991. It only operated from March 1991 till June 1992, a very short period. Klettwitz-nord was closed for economical reasons. It was planned to demolish the bridge, but then came the idea to make it open to the public.
In 2000 the bridge was ready to receive the first visitors. Since then, it has been a great Success.
