The Waldschlößchenbrücke (also Waldschlösschenbrücke ) is a road bridge over the Elbe below the Waldschlösschen in the Elbe Valley in Dresden . The crossing of the Elbe in Dresden, which was planned at the end of the 20th century, was and is controversial, and in the mid-1990s sparked what has become known as the “ Dresden Bridge Dispute ”. After a referendum in 2005, the bridge in the middle of the UNESCO World Heritage cultural landscape of Dresden Elbe Valley became known throughout Germany. Because of them, the Elbe Valley was put on the Red List of World Heritage in Danger and lost its World Heritage title three years later .
The bridge crosses the Elbe at one of its widest points and belongs to the Waldschlößchenbrücke traffic train with the connection of the bridgeheads to the road network - in the north with several tunnels - and the feeder roads to be expanded; the traffic train should relieve the Dresden Neustadt and the neighboring bridges. The bridge was officially opened on August 24, 2013.
Project description
purpose
The Waldschlößchenbrücke closes a traffic train on which the city center can be bypassed to the east. It creates a connection between the densely populated left Elbe (south) east of Dresden and the right Elbe north of the state capital with the industrial settlements in the vicinity of the airport . It relieves the four bridges in the city center and the Blue Wonder . It connects the main streets Stauffenbergallee and Bautzner Strasse north of the Elbe with Fetscherstrasse and the Käthe-Kollwitz-Ufer on the south side.
location
The crossing of the Elbe was built 2.5 kilometers east of the city center of Dresden between the districts of Johannstadt and Radeberger Vorstadt at river kilometer 52.68.
The northern bridgehead was built on the Elbe slope near the eponymous Waldschlösschen - originally a summer residence on the extensive grounds of the Saxon Minister Camillo Graf Marcolini on the edge of the Dresden Heath . Today this quarter is a residential and gastronomic quarter known as the Waldschlösschen area . The southern Johannstädter Ufer on the broad Elbe meadows is flat, the junction there was created not far from the “Clara Zetkin” nursing home and senior citizens' home, as well as from the buildings of the University of Fine Arts , the Heart Center , the Carl Gustav Carus University Hospital and the Max Planck Institute for molecular cell biology and genetics .
Involvement
The Waldschlößchenbrücke traffic train consists of the following sub-projects:
- four- to five-lane expansion of Stauffenbergallee ( already completed east of Königsbrücker Strasse )
- Tunnel system as a largely crossing-free connection of the northern bridgehead with Stauffenbergallee and Bautzner Straße
- actual Waldschlößchenbrücke
- Expansion of the Fetscherstraße / Käthe-Kollwitz-Ufer junction on the southern bridgehead, partially free of intersections
- multi-lane expansion of the northern Fetscherstrasse .
The intersection of the Stauffenbergallee feeder with Königsbrücker Straße (Olbrichtplatz) is not included in the transport train. A crossing-free expansion is also being discussed for this node. There is no direct integration of the traffic train to the west (accessibility of Großenhainer and Leipziger Straße) and to the south (accessibility of Teplitzer Straße or Zellescher Weg as an extension of the south-west tangent).
draft
The planning emerged from a competition that was won in 1997 by the Berlin office Eisenloffel + Sattler, Ingenieure - Kolb + Ripke, Architekten (ESKR). Among the 27 submitted designs, the one from ESKR (see under web links ) was awarded the 1st prize (75,000 DM). Members of the jury included the then mayor Herbert Wagner and - as chairman - the architect Volkwin Marg , who later distanced himself from the project (see Dresden Bridge Dispute ).
The 636.1 m long structure is a steel composite structure . It consists of three sections, the two approach bridges and the power field. The 274.81 m long foreland bridges on the left and the 213.49 m long foreland bridges are beam structures supported by V-shaped struts. The middle part of the bridge is supported by two steel arches with a span of 148 m, which rise about 26 m above the Elbe. They start on the ground under the roadway and carry the guyed roadway in the main part. The bridge is 28.6 m wide in the arch area and 24.4 m in the foreland areas and has two lanes in each direction, each 3.25 m wide. On the outside of the arches, there is a footpath and cycle path on each side, each 2.35 m wide. The gradient rises on both sides of the current field with a maximum of 4.3%.
The reinforced concrete deck is supported by two main girders, which are designed as trapezoidal steel troughs and are connected to the deck with headed bolt dowels .
Burger variant
In the hope of being able to avert the withdrawal of the World Heritage status, under the leadership of the former Frauenkirchen building director Eberhard Burger, in coordination with the architect, some cosmetic changes were incorporated into the design (compare Dresden Bridge Dispute ), most of which are now (regardless of the World Heritage withdrawal) should come to execution. However, it is controversial, for example, that the four staircases from the Elbufer (cycle) paths, which are only considered as retrofittable options, are no longer available. One of the Burger changes - reducing the bridge width by one meter - was considered to be so costly that its feasibility was not seriously examined, but only asserted against UNESCO and the public for a while. Only a few weeks after the decision to withdraw the World Heritage Site, city spokesman Kai Schulz announced that the non-implementation of this change had already been determined months earlier. Due to the unchanged width, the originally planned whip lights between the bike path and the vehicle lane can be retrofitted if the lighting from the railing handrail is found to be inadequate.
Construction and maintenance costs
The forecast total costs amounted to € 157 million.
By November 2006, € 27.9 million had been spent, including € 13.1 million for planning work and € 8.7 million for the renovation of Stauffenbergallee. The € 129 million still to be spent should go to the Free State (€ 96 million in funding ), the city of Dresden, the Dresden transport company (€ 5.5 million) and third parties ( DREWAG Stadtwerke Dresden , Telekom , etc. € 6.7 million) share. The planned construction costs were exceeded, in February 2010 the additional demands of the construction companies had already totaled € 42 million.
For the annual maintenance costs of the entire traffic train, 1,019,000 euros are calculated, with costs for the bridge alone amounting to 429,000 euros. The city's draft budget for 2013 and 2014 shows follow-up costs of EUR 3.768 million per year for the Waldschlößchenbrücke.
The emerging excess of the construction costs has been checked by an expert since April 2010 .
In June 2012, the Dresden Regional Court dismissed an action brought by the City of Dresden against the construction companies as inadmissible. The point in time is still too early to be able to assess the construction cost overruns. The subject of the lawsuit was additional claims by construction companies in the amount of two million euros due to higher steel prices.
In June 2018, the settlement of the construction costs was completed. The entire train cost 179 million euros, the construction of the bridge alone 74 million euros. In addition to the bridge, this also includes the Prießnitzbrücke , the Stauffenbergallee , which has been expanded to Königsbrücker Strasse, and the tunnel.
At the end of 2018, the construction costs were put at 180.7 million euros, plus open items (land acquisition and subsequent environmental protection) totaling 11.5 million euros.
chronology
prehistory
A bridge at the Waldschlösschen had been considered several times for a long time without actually being implemented. First considerations go back to the 19th century.
- → Section "Prehistory" in the article "Dresden Bridge Dispute"
planning
The first version of the planning documents that could be approved was submitted to the Dresden Regional Council on March 20, 2003, which issued the planning approval on February 25, 2004 .
- → Section "Planning" in the article "Dresden Bridge Dispute"
Construction work
In August 2008 the paddle steamer Stadt Wehlen of the White Fleet passed the construction site of the Waldschlößchenbrücke
Paddle steamer Kurort Rathen at the same location in April 2010
As a first preparation, all four garden areas ( Am Waldschlößchen , Elbblick , Jugendgarten and Nord ) on the Waldschlösschenwiese were cleared from January 6, 2000.
As part of the election campaign for the office of Lord Mayor , incumbent Herbert Wagner broke the first sod for the Waldschlößchenbrücke on November 29, 2000 - regardless of the failure of the planning approval at that time due to missing documents and exceeding noise limits and regardless of the feared conflicts with the requested World Heritage reserve . Subsequently, individual construction work was carried out in the peripheral areas of the traffic train, which was possible without the approval of the overall project or is only indirectly related to it:
- Soundproof fence for a garden division on Käthe-Kollwitz-Ufer (2001)
- New festival area at Marienbrücke (2003)
- Expansion of the Stauffenbergallee
- Demolition of the buildings Waldschlößchenstrasse 9 to 13 (2005)
- Demolition of buildings on the former Stasi site at Bautzner Strasse 110 and 112 (2006)
It was not until the end of May 2007 that the formal prerequisites for the start of construction were in place (six and a half years after Wagner's “groundbreaking”): the regional council had ultimately asked the city of Dresden to award the construction contracts for the right-hand Elbe bridge connection , and the constitutional complaint lodged against it had failed . On June 8, 2007, the regional council itself made the award decision by substituting . In the following week, the regional council also decided on the awarding of all further construction phases. When asked whether the city was writing off the receipt of the World Heritage title, Dresden's building mayor Herbert Feßenmayr (CDU) replied according to dpa : "That is probably the case."
The start of construction, initially planned for August 13, 2007, was delayed until November 19, 2007 due to a construction freeze imposed by the Dresden Administrative Court for nature conservation reasons , which, however, was lifted by the Higher Administrative Court . During the winter months, with protests from Dresden citizens and celebrities (including Günter Grass ), trees were felled on Waldschlößchenstraße, Bautzner Straße, Stauffenbergallee and Käthe-Kollwitz-Ufer, as well as earthworks and foundation work on the Elbe meadows on both sides of the river.
On January 15, 2008, a 280-year-old European beech tree was felled on the corner of Bautzner Strasse and Angelikastrasse , with great media interest , which still came from the English Park that Marcolini had created there. The tree had been occupied by activists from the environmental protection organization Robin Wood since December 12, 2007 and became a symbol of the peaceful protest of many Dresdeners against what they believed to be the oversized planning of the Elbe crossing. The planned felling on January 10th was initially prevented by the tree occupation and the presence of Dresden citizens. A rescheduling like the one in the Stockholm Elm War could not be achieved in the end, and even demonstrators are said to have been mistreated by the police during the evacuation before the felling work .
On April 17, 2008, five Robin Wood members occupied a crane on the construction site of the bridge abutment on the Neustadt side, thereby obstructing the construction work for a few hours. In addition, two acts of sabotage were carried out by strangers on the bridge under construction: on February 7, 2008, formworks were poured over with caustic liquids and on April 28, 2008 sand was placed in a hydraulic gearbox.
According to the Sächsische Zeitung, cracks in the houses appeared in 2009 in some houses near the tunnel construction.
Building bridges
The middle section ( arch of the bridge ), built 60 meters downstream from the bridge location on the bank, was inserted using the floating method and placed on two auxiliary supports in the Elbe on December 19, 2010.
designation
After a long discussion between summer 2011 and January 20, 2012, the Dresden city council decided to use the previously unofficial name Waldschlößchenbrücke as the official name of the bridge.
Traffic load
For the Waldschlößchenbrücke a traffic load of 45,000 vehicles / day has been forecast for the year 2025. In 2015 it was 34,000 vehicles per day. On the Carolabrücke, the load decreased by 5,000 vehicles / day after the bridge was opened, and on the Blue Wonder by 3,000 vehicles / day. The bridge is used by cyclists with a load of 3,500 cyclists / day in 2014.
