# Bundesautobahn 23

Bundesautobahn 23 (translates from German as Federal Motorway 23, short form Autobahn 23, abbreviated as BAB 23 or A 23) is an autobahn in Germany. It runs largely parallel to the Bundesstraße 5; its main purpose is to connect the hinterland of Hamburg. North of Heide, the A 23 becomes B 5 and connects Eiderstedt, Husum and the ferries to the islands of Nordfriesland to the autobahn network.
