The A6 motorway, an Autobahn in Switzerland, connects Biel / Bienne over Bern with Mülenen.

The A6 is located entirely within the Canton of Bern and, in particular, has a great regional significance, as only the section of Bern in the direction Berner Oberland is part of the Swiss national road system.

The A6 leads up the Aare valley to Thun, and from there to the junction of Lattigen near Spiez.

At this junction, the A6 turns south to Mülenen while the motorway going southeast changes into the A8.

Earlier, there had been plans to continue the national road through the Simmental and then connect it with the Canton of Valais through the Rawil-Tunnel, but this project was abandoned in 1984.
