The Neckar Bridge is a 345 m long railway bridge planned as part of the Stuttgart 21 project between Stuttgart Central Station and Stuttgart-Bad Cannstatt Station .

The bridge replaces the existing four-track Rosenstein Bridge , which stands south of the new structure.

course

The structure is to bridge the Neckar , Schönestraße , Neckartalstraße ( Bundesstraße 10 ) and a stretch of the Stuttgart city railway used by the U14 with eight fields ( continuous beams ).

Are on the construction train and remote web are performed together in parallel with a total of four tracks. The S-Bahn is to run on the northern part of the bridge at a design speed of 80 km / h, the long-distance train on the southern part.

On the Rosenstein Park side , the tracks will lie on two separate, double-track superstructures before they merge into the double-track tubes of the new Rosenstein tunnel and the Bad Cannstatt tunnel .

Due to the restricted space available, a transfer point is to be placed between the long-distance railway tracks at the eastern abutment .

construction

Substructure

In the middle of the river and on the mole on both sides of the Neckar, 3x3 concrete pillars are planned in the bank area, and steel supports in the foreland areas.

The trough of the adjoining tunnel is the landside support of the approach bridge and is connected to the concrete deck of the bridge.

history

planning

The bridge was designed by the Stuttgart engineering office Schlaich Bergermann und Partner . With its model from 1998, the office emerged from an ideas competition to which four Stuttgart engineering offices had been invited. After a pillar was initially planned in the Neckar, this was not used in the further planning process. The bridge is part of the planning approval section 1.5 of the Stuttgart 21 project, for which the planning approval decision was available on May 29, 2008.

The wooden footbridge over the Neckar , which was built for the Federal Garden Show in 1977 , was demolished for the building; during the roughly four-year construction period there was no replacement for the footbridge. The Rosenstein and König-Karls-Brücke are named as alternative options . The new bike and footpath should be suspended below the new railway bridge. In mid-July 2013, a few hundred people demonstrated against the demolition, and demolition work began in June 2016.

After exploratory drilling in January 2013, two pillars are to be moved by up to three meters.

The bridge is planned and implemented using Building Information Modeling .

Tendering and awarding

At the beginning of April 2014, Deutsche Bahn announced the construction of the bridge across Europe. The construction contract to be awarded is to run from February 1, 2015 to December 31, 2018. The estimated costs of the bridge were initially under lock and key (as of February 2015). In November 2015, the railway awarded the construction contract for around 35 million euros to Max Bögl . The construction costs were estimated at 40 million euros in October 2017.

According to the planning status from mid-2013, construction work should start in November 2014. The start of construction planned for September 2015 was postponed according to information from July 2015. According to the Deutsche Bahn, the award is still planned for the second half of 2015, but a significant change in the plans requires approval from the Federal Railway Authority. A row of supports should be dispensed with and a row on the bank should be moved further away from the river. This means that construction under compressed air can be dispensed with and the usual pile foundation can be used. A total of 19 supports are now planned.

The bridge was to be pushed forward in 15 cycles in the direction of Seilerwasen using the incremental launching method. Bridge parts are delivered, welded on site and provided with rust protection. The end pieces on both banks should be lifted directly.

On August 14, 2017, the first bar of now 12 bars was inserted. At the beginning of 2018, the feeding beak had reached the central pier. In March 2018, six of twelve bars were inserted. On May 17, 2018, the ninth feed, with which the feed bill reached the southern bank of the Neckar, took place. With each cycle, the structure was advanced by 15 to 25 m. The twelfth and final advance of 15 m in length took place on August 7, 2018. A total of 213 m was advanced.

Up to 15 workers were busy assembling the bridge, which consists of 30,000 individual parts. The bridge parts were manufactured in Neumarkt in der Oberpfalz , the large bridge parts were delivered to the construction site at night.

The steel assembly for the shell and the construction of the abutments should be completed in 2018 and the construction of the approach bridges should begin. The completion of the shell is planned for the end of 2019. After completion of the railway bridge, a footbridge for pedestrians and cyclists will be hung below the structure. The jetty should be usable from the end of 2019. In mid-2019, it was announced that it would be postponed to the first half of 2020. The assembly of the footbridge is scheduled to begin in summer 2019.

The bridge is to be inspected before it goes into operation for train traffic at the end of 2025.

The concreting of the carriageway slab should be completed by the end of 2019.

Once the construction work has been completed, the neighboring Wilhelma plans to set up a small enclosure for pygmy hippos in front of its main entrance on the Neckar .

technology

A conventional ballast superstructure is planned for the bridge .

The steel sails of the bridge structure should also serve as noise protection. A sound-absorbing concrete trough and sub-ballast mats should also serve to protect against noise. A three-meter high soundproof wall is also to be built next to the bridge. This should reduce noise emissions in the adjacent residential and mixed areas and, if necessary, increase them slightly.
