Bundesautobahn 27
branches off the A 7 at Autobahndreieck Walsrode to the northwest, crossing A 1 at the Bremer Kreuz and continuing eastwards of Bremen, toward Cuxhaven.
Due to the large ports alongside the Autobahn, there is heavy truck traffic.
Its northernmost part, between Bremen and Cuxhaven, largely replaced the Bundesstraße 6, although some maps still show the B 6 within the city limits of Bremerhaven.
