BlauesWunder) is a cantilever truss bridge over the Elbe river in the German city of Dresden.
In fact, a number of news articles and other sources show that the original colour was really blue; when the bridge was opened for the first time, it was already hailed as the "Blue Wonder".
In addition, the name is a pun, since the meaning of the phrase "ein blauesWunder erleben" is "to experience a nasty surprise".
