Bundesautobahn19 (translates from German as Federal Motorway19, short form Autobahn19, abbreviated as BAB19 or A19) is an autobahn in eastern Germany that connects the Baltic port of Rostock to the A24, which continues to the A10 ring road around Berlin. The Warnowtunnel is the only stretch of autobahn so far that requires the payment of a general road toll for all vehicles.
