The A 831 towards Singen at the Stuttgart intersection |
The Stuttgart motorway junction (also: Stuttgarter Kreuz ; abbreviation: AK Stuttgart ; short form: Kreuz Stuttgart ) is a motorway junction in Baden-Württemberg in the Stuttgart metropolitan region . The cross connects the motorways 8 ( Saarland - Stuttgart - Munich - Salzburg ; Europastraße 52 ), 81 ( Würzburg - Stuttgart - Singen (Hohentwiel) ; Europastraße 41 ) and the A 831, which is only a few kilometers long . The Stuttgart junction has a very high traffic density.
geography
The cross is located south of Stuttgart on the city limits between Stuttgart and Sindelfingen . It is located about ten kilometers southwest of Stuttgart, about 55 kilometers southeast of Karlsruhe and about five kilometers northeast of Böblingen .
A few kilometers west of the cross is the Leonberg motorway triangle , which also has a high traffic load.
The junction on the A 8 is junction number 51, on the A 81 it is number 20 and on the A 831 it is number 2.
History and state of development
The motorway junction was originally designed as a clover leaf . However, it was changed by a direct connection from the A 81 from the direction of Singen / Hohentwiel to the A 8 in the direction of Karlsruhe in order to be able to cope with the heavy traffic in this relation.
Initially it was planned to run the A 81 directly between Gärtringen and the Leonberger Dreieck and the original Leonberger Dreieck in the shape of a trumpet would have become a motorway junction. However, the B 14 in the Stuttgart-Vaihingen to Böblingen section had already been developed as an expressway. Therefore, the A 81 was "initially" connected to this expressway and the section was rededicated as a motorway. Environmentalists then successfully defended themselves against the construction of the originally planned section, so that this plan was finally rejected. The changed planning then required the above-mentioned expansion of the Stuttgart cross and the Leonberg triangle. The section in between was also expanded to four lanes in each direction plus a hard shoulder, as north-south and east-west traffic overlap with the heavy traffic in the greater Stuttgart area.
The Gärtringen junction still bears witness to the original planning. The already built first section of the continuation serves today as an entry and exit from the direction of Singen. Therefore, coming from the direction of Singen, take the left lane off the autobahn.
The motorway junction was originally called the Stuttgart-Vaihingen motorway junction , while today's Leonberger Dreieck was called the Stuttgart motorway triangle .
Particular importance for Stuttgart
Seen from the A 8, the A 831 offers one of only two ways to reach the Stuttgart core area, as indicated by the Stuttgart-Zentrum signs . Only via junction 52b to the east - signposted as junction Stuttgart-Degerloch - you can also get to the center via the B 27 . This traffic structure, known regionally as the “ Echterdinger Ei ”, is similar to a motorway junction.
Traffic volume
It is used by around 227,000 vehicles every day, making it one of the busiest road junctions in Baden-Württemberg. There are often major traffic jams around the motorway junction.
