Bundesautobahn 19 (translates from German as Federal Motorway 19, short form Autobahn 19, abbreviated as BAB 19 or A 19) is an autobahn in eastern Germany that connects the Baltic port of Rostock to the A 24, which continues to the A 10 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.
