Bundesautobahn 270 (translates from German as Federal Motorway 270, short form Autobahn 270, abbreviated as BAB 270 or A 270) is an autobahn in Germany. The A 270 was created in 2001 as a redesignation of the freeway into the northern part of Bremen. Previously, the freeway was known as the B 74n Lesumerschnellweg. The freeway replaced the route of the through the populated areas of northern Bremen. As is expected for urban freeways, some of the junctions are only accessible from one direction; one junction (3b, Lobbendorf) does not permit autobahn traffic to exit at all.
