Bundesautobahn27 (translates from German as Federal Motorway27, short form Autobahn27, abbreviated as BAB27 or A27) branches off the A7 at AutobahndreieckWalsrode to the northwest, crossing A1 at the Bremer Kreuz and continuing eastwards of Bremen, toward Cuxhaven.
Due to the large ports (especially in Bremerhaven) alongside the Autobahn, there is a lot of heavy truck traffic present.
Its northernmost part, between Bremen and Cuxhaven, largely replaced the Bundesstraße 6, although some maps still show the B6 within the city limits of Bremerhaven.
