Until the year-end 2006, the route led to Duisburg. The formerly part between Duisburg-Wanheimerort via Duisburg-Dümpten and Oberhausen-Alstaden to the current starting point has been downgraded to a road and now it has been renamed to Landstraße 1 . The part between Frintrop and the Westviertel has a tram connection within.
