This bridge is probably only famous among railway fans (at least fans of German railways). It was on the 'WCd-Linie', the first narrow-gauge railway built in Saxony. The line was closed by the communist government (against local opposition) decades ago, this bridge - in bad shape by then - was turned to scrap metal. Now a section rebuilt for tourists by a civilian initiative ends some distance from the bridgehead.
This US-style simple iron construction is rather rare in Europe (but, a bridge almost exactly like this survives on an Austrian narrow gauge museum railway). *Lunatic*, n. One whose delusions are out of fashion.
