The northern part, to the Starnberg 3-way interchange is adapted to the needs of a large city (in this case, the road has been expanded to six lanes).

In the area of the Starnberg 3-way interchange a 120 km/h (ca 75 mph) limit was imposed until November 2007, ending a four-year trial period.

Now the route was planned on the German side from Basel to Salzburg (Bundesautobahn 98) with a branch connecting Munich.

[3] The planning for the A 98 was stopped in 1980, due to the enormous cost, insufficient demand and lack of demonstrable acceptance.

[8] The further construction to Garmisch-Partenkirchen was planned for 1960, however since May 2000 there is only an approximately four Kilometer (ca 2.5 Miles) long bypass of Farchant, though it is signed as B 2.

The plan is to continue to bypass Oberau with a West-tunnel, the Auerberg tunnel and a connection to the B 23n towards Reutte and Schongau.

[9] Between the Schäftlarn and Wolfratshausen junctions is a rest area with a consistently managed service station on both sides of the motorway.
