Jahnstrasse (Stuttgart)
.jpg)
The Jahn street in Stuttgart is a multi-lane road that the district Degerloch with the Municipality Stuttgart East combines. It gained importance in particular through the construction of Mittlerer Filderstraße , an important bypass road opened in 1953 in the south of Stuttgart, which flows into Jahnstraße on the Bopser . This was therefore greatly expanded in 1954, whereby it was designed as a pure concrete road . The oldest concrete street in the city was previously located in Jahnstraße, and when it was renovated in 1954 it was the second pure concrete street that was laid out in Stuttgart after the Second World War.
Location and development
The Jahnstraße begins north of the center of Degerloch at the fork in theöffelstraße , which divides there into the Obere and Neue Weinsteige to Stuttgart-Mitte and the Jahnstraße further east. The Jahnstraße leads to the northeast, initially through a modern residential area that is rather loosely built due to the hillside location and then forms the northern boundary of Degerloch. After the road has passed the sports facilities, including the Gazi Stadium on the Waldau , on the northeastern edge of Degerloch, it leads in several generous swings through the forest over the Bopser , where Mittlere Filderstrasse joins it from the south, and on to the northwest Direction Stuttgart-Ost . When you leave the forest, it turns into Pischekstraße at the level of the Merz school in Stuttgart-Ost .
There is essentially only development along Jahnstraße in the short section from the fork inakenöffelstraße to the outskirts of Degerloch. The district medical association of North Württemberg is housed in a new building at Jahnstrasse 5, which also owns the neighboring Villa Taubenheim , a listed building . On the site of the new building erected in 1987 was the summer residence of Antonie von Siemens , wife of the company's founder Werner von Siemens , from 1870 until it was demolished in 1957 . The building served as Emil Reinert's sanatorium from 1913 to 1939 . The publisher Euchar Nehmann ( Franckh-Kosmos ), who had set up an observatory in the rooftop of the villa, lived in the nearby villa at Jahnstrasse 40 . Generous villa development continues south of Jahnstrasse.
The address Jahnstraße 120 is the Stuttgart TV tower , another tower on Jahnstraße is the Degerloch water tower .
history
The Jahnstraße in Degerloch was originally called "Bahnhofstraße" and was given its current name in 1928. Both the Stuttgart cogwheel railway and the Filderbahn stopped at the first Degerloch cog railway station on Jahnstrasse, which was demolished in 1931 . In the further course over the Bopser, the Jahnstraße goes back to the local network of old farm roads. B. the Dobel blade follow the geographical conditions.
The Jahnstraße connects the Bopser with the Geroksruhe viewpoint over a length of 1.6 kilometers . In 1929, a 480 meter long section of the road had already been constructed as a concrete road. The street was six meters wide, the ceiling thickness was 13 centimeters. The old pavement has made an 8-centimeter-thick undercoat of Moränekiessand , chalky gravel and 220 kg of cement per cubic meter and a 5-centimeter-thick top layer of Moränekiessand with Diabassplit composed 15/25 and 355 kilograms of cement per cubic meter. The old concrete road section was designed without longitudinal joints, reinforcement and dowelling, so that after the Second World War, with the increase in motor vehicle traffic, longitudinal cracks soon appeared. The remaining sections of Jahnstrasse were no longer able to cope with the increased traffic.
After the opening of Mittlere Filderstraße in 1953, which bypasses Degerloch, Hoffeld and Schönberg in the east and joins Jahnstraße on the Bopser from the south, the surrounding streets were adapted to the new traffic conditions from summer 1954. For Jahnstrasse, which in future primarily had to take up all the traffic flowing north over Mittlere Filderstrasse to the center of Stuttgart, it was decided to design it as a concrete road over the full length of 1,600 meters. Construction work on Jahnstrasse began on July 13, 1954.
The width of the carriageway was increased to 10.10 meters, of which the carriageway took up 7.50 meters and the hard shoulder 1.30 meters each. The new concrete pavement was applied to the old street, with a wider strip next to the narrower old street being compacted. Between the old roadway and the new concrete pavement, a 15-centimeter-thick, graded layer of sand and gravel made of washed Rhine material with a grain size of up to 30 mm was placed, which was also compacted with rammed piles and vibrating plates . The concrete used for the pavement was mixed with 350 kg of road cement 225 per cubic meter of concrete. Because of the low proportion of fine sand in the Rhine sand used, a plasticizing agent was added to the concrete as an air-entraining agent. On the uphill sections (max. 7.6%) of Jahnstraße, the road surface was made rough by means of pressure- reinforced Piassava brooms , while flat sections of the road were given the usual broom mark. The road surface was reinforced with steel mats on around 65% of the total area. The total area of the road construction is approx. 14,000 m².
