Following flood damage, the bridge was reopened as Friedrichsbrücke in 1902.  To make the inner city ring road more car friendly, the structure was replaced by an oval shaped twin bridge, which was opened as Kronenbrücke in 1969.  Since the structure is not for a newly planned tram line, the bridge was demolished to make way for a new replacement bridge, which is to be completed by the end of 2018 .
