The Southern Bavaria Highway Authority is planning a four-lane extension of the B2 between the end of the A95 at Eschenlohe and Garmisch-Partenkirchen. The main component of the extension is the 1,900 m long "Auerberg" tunnel, which is designed as a twin-bore tunnel. Both of the tunnel bores cross over the "Vestbühl" dringking water gallery with little spacing.
