Just got one of these maps
bgl-ev.de/daten/news/2009/BG … LSEITE.PDF
Shows all the roads with a saturday holiday ban plus alternative routes, roads where lorries are banned completely and info about the eco-zones in many German cities, a good little map in fact.
Its published in may each year by the BGL (German transport association), I got mine from the firm where I’m working at the moment but you can order it here:
bgl-ev.de/web/service/angebo … .htm#karte
at the bottom of the page, costs about Euro 5 as far as I can make out.
