The Bundesstraße 248 (abbreviation: B 248) is a German federal highway that runs from Northeim to Dannenberg (Elbe),[1] where it ends in the town at its junction with the B 191.

In Wolfsburg the old B 248, widened to four lanes in the 1960s, has been renamed today as the A 39 motorway (autobahn).

The southern section of the present-day Bundesstraße 248 between Northeim and Brunswick was referred to by the Duchy of Brunswick as Frankfurter Straße and upgraded between 1786 and 1794 into a surfaced road (chaussee).

The centre section between Brunswick and Wolfsburg was upgraded into a chaussee between 1805 and 1816 and called the Berliner Straße.

This federal highway was cut in two places by the division of Germany and could not be driven from end to end again until 1989, when the border crossings between Brome and Mellin (on 18 November) and between Salzwedel and Lübbow were re-established.
