Bundesautobahn 9 (translates from German as Federal Motorway 9, short form Autobahn 9, abbreviated as BAB 9 or A 9) is an autobahn in Germany, connecting Berlin and Munich via Leipzig and Nuremberg.


Potsdam interchange

The northern terminus of the A 9 is at the Potsdam interchange, where it merges into the A 10, also known the "Berliner Ring", about 30 kilometres (19 mi) away from the Berlin city limits. The shortest route from there into Berlin would be the A 10 (east) and the A 115 (AVUS). The southern end is in the Munich borough of Schwabing.

On its way, the A 9 passes through the German states of Brandenburg, Saxony-Anhalt, Thuringia, and Bavaria. West of Leipzig, the border between Saxony-Anhalt and Saxony crisscrosses along the autobahn. In Bavaria, long sections of the Nuremberg–Munich high-speed railway run parallel to the autobahn.


Plans for a European motorway connection from Berlin to Rome were already developed from 1927 by a private MüLeiBerl (Munich-Leipzig-Berlin) company. However, construction of the A 9 was not begun until the 1930s as part of the Reichsautobahn project set up by Nazi Germany.

It was inaugurated in sections, beginning in 1936 with the Strecke 16 between what is today's Schkeuditz interchange (present-day A 9 and A 14) near Leipzig and Bad Berneck im Fichtelgebirge, 164 kilometres (102 mi) in length. With the opening of the second lane near Schnaittach in 1941, the last gap was closed. This makes the A 9 Germany's first completed autobahns.

After World War II, the section from the inner German border to Berlin served as one of four transit access roads through East Germany (GDR) toward West Berlin during the Cold War era. Yellow signs with "TRANSIT" in black letters marked the allowed route. Distances were usually given towards Berlin - Hauptstadt der DDR ("Berlin - Capital of the GDR"), i.e. East Berlin. Despite funding from West Germany, road conditions were generally poor. The surface was made up of 1930s concrete slabs rather than blacktop or continuously cast concrete. A section in Thuringia between Schleiz and the Rodaborn rest area even was a cobblestone road, later paved over by the East German authorities until being replaced by concrete in the 1980s. Until the introduction of a new numbering system in 1974, the southern part was known as the West German A 3.

Railbus crossing the A 9 near Bayreuth, 1986

After German reunification, the A 9 was to be extensively rebuilt and upgraded, being "German Unity Transport Project" No. 12. The old two-lane profile without emergency lane was in no way suited to modern levels of traffic, speed, and expected safety. In 1990, 50,000 vehicles per day were counted near Bayreuth, about as much as the motorway could handle. After the work was finished near Bayreuth in 2006, the only part of the old profile is in Thuringia between the Schleiz and Triptis junctions. Planning for the upgrade is in progress, as it is the last bottleneck on the A 9.[1] Once this construction is finished, there will be at least three lanes plus emergency lane in each direction for the whole route.

Current condition and future plans

A 9 near Münchberg, Bavaria

With two exceptions, the A 9 has a profile of at least three lanes and one emergency lane per direction. Exceptions are the Hermsdorf interchange and the 19 km (12 mi) two-lane stretch south of Triptis. The section between Neufahrn and the München-Nord interchange north of Munich has been upgraded to four lanes each way. This part was surveyed in 2008 with an average number of 143,000 vehicles per day with a maximum of 184,000.

Since 2006 talks have started about turning the three-way interchange Holledau into a four-way, and extending the A 93 into the Pfaffenhofen area. Further plans and visions include widening to six lanes between Triptis and Schleiz in Thuringia until 2014, and to eight lanes between interchanges Nuremberg and Nuremberg-East, and Holledau and Neufahrn, respectively.

Along the route

Vockerode Elbe Bridge tower, c. 1984

East of Dessau, the autobahn crosses the Elbe River via the 654 m (2,146 ft) long Vockerode Bridge. Built in 1938 according to plans designed by Paul Bonatz, it was replaced by a new construction in the course of the A 9 extension from 1996 to 2000. The prominent tower at the northern end is preserved, it was widely known to transit travellers for its Plaste und Elaste aus Schkopau ("plastic and elastomer from Schkopau") neon sign, now on display at the German Historical Museum in Berlin.

Close to exit 10, Dessau-East, a gravel pit had provided material for the construction of the autobahn. After 1939 the pit was renaturated and became the "Reichsautobahnbad Mildensee", with cabins to change, and eateries. It is still in use today as a beach, but not under the old name.

Dessau Racetrack with modern jersey barrier median

South of exit 11, Dessau-South, nearly ten kilometers of the roadbed — roughly from Thurland southwards to just north of the B 183 interchange (exit 12 for Bitterfeld/Wolfen of the modern A9 roadbed) — were upgraded with a paved-over median to become the "Dessauer Rennstrecke" (Dessau Racetrack), a 25 meter (82 ft) wide high-speed track intended for races and record attempts, such as by Rudolf Caracciola in 1938/39 or those by Hans Stuck with the Mercedes-Benz T80 land speed record car, starting in January 1940. With its pillarless bridges, but especially with the straight alignment and the broad concrete surface without a distinct median, it was also intended to function as an auxiliary airfield in World War II. After the war, annual races were resumed from 1949 to 1956. The East German driver Paul Greifzu was killed in a training accident on 10 May 1952.

The four-way interchange at Schkeuditz was the first cloverleaf interchange in Germany, as well as the first autobahn interchange in Europe. It was opened in 1936, two years before construction was finished.

On June 30, 2004, Germany's oldest autobahn inn, Rodaborn near Mitropa. The rest area was open only for transit travellers, not for East German citizens. In 2009, in a loop of history, it was rented by a local couple to re-open it as an inn for local daytrippers. Though the connection to the adjacent autobahn parking lot is cut off by a fence, Rodaborn still is a popular stop for motorway travellers.

Old and new Saale Bridge

The Rudolphstein Saale Bridge south of Bad Lobenstein, an arch bridge designed by Paul Bonatz, was opened on 27 September 1936 and soon became an icon of the Reichsautobahn development program. Between 1945 and 1966 the A 9 was interrupted at the inner German border between Bavaria and Thuringia since an arch of the bridge had been blown up by retiring Wehrmacht forces near the end of the war. Traffic to and from West Berlin was diverted via A 72 until 1951 and from then until 1966 via B 2. Not until then the bridge could be rebuilt in a complicated joint venture of West and East German authorities. In the course of the autobahn extension, a second bridge was erected prallel to the original construction.

The Frankenwald rest area near exit Rudolphstein is one of two rest areas in Germany with a restaurant bridging the road.

In Lanzendorf near Bad Berneck, the autobahn passed right through the village on a bridge. The route was realigned during the construction after 1990. Right next to the old route, the autobahn church Lanzendorf was built. Sanctification took place October 6, 1996.

Exit 40b, Bindlacher Berg, was until after reunification no public exit, but used exclusively by the US Forces stationed on the Bindlacher Berg.

Until the upgrade to six lanes, from Bayreuth-Nord to Bindlach existed the last autobahn alley of trees in Germany. It has been replanted since.

Near Trockau, the former steep and curvy section also was realigned after 1990.

Exit 45, Weidensees, was called "Veldensteiner Forst" until the 1970s and was probably built on behalf of Hermann Göring, who had a hunt nearby. Weidensees itself did not merit its own exit.

Interchange 51, Nuremberg, was originally a cloverleaf. It had been improved by adding a long, sweeping bridge from the northern lane of the A9 coming from Munich towards the A3 in the direction of Würzburg and Frankfurt, since the traffic in that direction was much heavier than the traffic heading north. The old, small curve in the former south-east quadrant still shows what is probably the original 1930's cobblestone.

Despite the upgrade to six lanes total, some original bridges have been retained, but carry just one direction, like the bridge crossing the Saale at the old border crossing between Bavaria and Thuringia.

From 2000 until construction began to upgrade to four lanes for each direction, the section between Neufahrn and Munich-Nord was among the first in Germany where it was allowed in appropriately heavy (and correspondingly slow) traffic to legally use the emergency lane as an additional traffic lane. Since further adding of two more lanes north of Neufahrn towards Holledau is not in sight, a similar regulation is considered for this section.

Near exit 73, München-Fröttmaning, there's a Berlin Bear statue placed on the median (). Its equivalent is placed on the median of the A 115 (as the extension of the A 9 into Berlin) near former rest area Dreilinden, north of the former checkpoint Bravo .

At the entrance to the rest area "Köschinger Forst", direction Berlin, there's a milestone with the inscription Berlin - 500 km.
