The first railway bridge with this name was built as part of the Zentralbahn and put into operation in 1846. They rested on eight central pillars, with the blasting works were executed in wood. In 1858 this was replaced by a cast iron bridge.

construction

The construction of the new bridge and the new tunnel was put out to tender in 1911 by the General Directorate of the Royal Württemberg State Railways in order to be able to lay a third and fourth track for suburban traffic in Stuttgart on the Cannstatter route . 2.5 million mark , according to a present-day equivalent of about 14 million euros , which was awarded the Karlsruhe branch of Dyckerhoff & Widmann AG the contract. The architect was Martin Mayer , who also designed the reception building of the Stuttgart-Bad Cannstatt train station. Its length is 244.03 m.

The bridge was made entirely of concrete, in particular on the pillars it was partially clad with natural stone, the remaining areas are designed as exposed concrete . It spans the Neckar in seven irregular arcs between 16 and 61.6 meters wide and describes a curve with a radius of 500 meters. In the direction of Bad Cannstatt there is a regular gradient of 5.6 per thousand.

The two pairs of tracks on the bridge were given a track spacing of 3.50 meters, which widens to 7.50 meters in the direction of Bad Cannstatt station. At the exit from the Rosenstein tunnel, the two inner tracks are 5.80 meters apart, which initially narrows to 4.00 meters and then widens again to 4.80 meters in the direction of Bad Cannstatt. Pillars 2 and 5 were widened to accommodate the entry and exit signals for Bad Cannstatt station and the Rosenstein tunnel. The length of the bridge is 322.3 meters, the width is initially 17.90 meters, then narrows to 15.0 meters in order to reach a width of 24.0 meters in front of the station.

Construction work began in the summer of 1911, initially on the Cannstatter side, and work on the left abutment began in April 1912. In the autumn of 1913, the work was interrupted due to unfavorable weather and was completed in the spring of 1914. A total of 40,5000 m³ of concrete was poured, the construction costs amounted to 1.6 million marks.

On November 25, 1915, the bridge was put into operation together with the Rosenstein tunnel.

Second World War

The Rosenstein Bridge was also hit in 1944 during Allied air raids during World War II . On the morning of April 21, 1945, the two middle arches were blown up before Allied troops could move in. From May 9, 1945, an American pioneer bridge connected the two banks of the Neckar at the Bad Cannstatt train station. Between November 23, 1945 and July 13, 1946, a shuttle service was offered between Stuttgart main station and the provisional entry point Rosenstein tunnel (route kilometers 2.2). On June 13, 1946, a single-track temporary bridge was put into operation. From 1949 the bridge was again available with four tracks.

Stuttgart 21

As part of the Stuttgart 21 project, the bridge is to be replaced by a new Neckar bridge and will be demolished after the new railway facilities have gone into operation. Their dismantling is not part of the planning approval procedure. Originally (variant S5 of the Stuttgart 21 preliminary project from 1995) it was planned to keep the Rosenstein Bridge and to renovate it while it was still in operation. Preservation of the bridge, combined with a transfer to the city of Stuttgart, was considered in 2015. Consideration is given to converting the railway bridge into a connecting route for pedestrians and cyclists. The city of Stuttgart is examining such a conversion, a decision has not yet been made (status: February 2016).
