Bundesstraße 23 (abbreviated to B 23) is a German federal highway (German: Bundesstraße) in Bavaria that runs from Peiting to the Austrian border near Garmisch-Partenkirchen. The road is partially a part of the “German Alpine Road” (German: Deutsche Alpenstraße). The B 23 which together with the Bundesstraße 17 and Bundesstraße 472 the quickest way from Augsburg to Garmisch-Partenkirchen, continue along the Bundesstraße 2 to Mittenwald, Innsbruck and the Brenner Pass.


The B 23 starts at the B 472 (bypass Schongau - Peiting) exit Peiting-south in the Weilheim-Schongau district and initially leads to Rottenbuch. This stretch was a few years ago in a poor state of development which have occurred some more serious accidents. In recent years, this segment has been expanded.

After the main through-road of Rottenbuch reaches the line the “Echelsbacher Brücke”. The 183 m long and 76 m high arch bridge spanning the Ammer. On the bridge there is also the border of the district of Garmisch-Partenkirchen.

The road pass Bad Bayersoien and reach Saulgrub. Currently being built a local diversion around Saulgrub to ease traffic congestion through traffic. In Saulgrub the B 23 meet the Ammergau Railway (Murnau / Oberammergau) for the first time.

It follows village Unterammergau. The road pass the local diversion of Oberammergau and reach Ettal. After the road cross the village, it achieve the “Ettaler Sattel” (869 NHN) the highest point on the route. The way winding along twisting road into Loisachtal. Here reaches the route Oberau and the Bundesstraße 2. The two roads run parallel to six kilometers (3.7 miles) towards the south. After the bypass Farchant separates the B 23 from the B 2 and runs in a southwesterly direction to Garmisch-Partenkirchen.

After B 23 has crossed Griesen the route end at the border with Austria (Tyrol), where it merges into the Austrian B 187 (towards Lermoos, Fernpassstraße, Inn valley).



Probably in the Roman period, but no later than at the time Louis IV, there was a connection between the Via Claudia in the Lech Valley to the Brenner road in the Loisach Valley.

The most difficult part of this route led from Rottenbuch to Bad Bayersoien by Echelsbach gorge. Therefore between 8 November 1928 and 27 April 1930 Echelsbacher Brücke was built for ℛℳ 900 000 .

Former routes and designations[edit]

The Bundesstraße 23 arise from Reichsstraße 23 at 1949. At that time, the R 23 began in Peiting at the intersection "Schongauer Straße" / "Oberere Straße" / "Guggenbergerstraße" at the then R 17 and ended in Oberau at the junction with the R 2. With the introduction of the Bundesstraßen the B 23 was extended on Farchant to Garmisch-Partenkirchen. There they led to the B 24.[1]


The Local diversion Oberammergau opened to traffic in 1989.[2]

The extension of the route from Garmisch-Partenkirchen to the Austrian border at Griesen in 1991. The B 24 was integrate in the new B 23. The remainder in Garmisch-Partenkirchen municipality was downgraded.

In 1991, following the release a segment of the bypass Schongau - Peiting the beginning of the B 23 changed to B 17 exit Peiting-West. The main through-road of Peiting was downgraded to a state road (German: Staatsstraße). The relocation to the present location was made after completion of bypass Schongau - Peiting in 1997

In May 2000 the Farchanter Tunnel was opened.[3]
