The Schiersteiner Brücke is a 1280 meter long, previously four-lane motorway bridge on the A 643 over the Rhine .
At river kilometer 504.4, it spans the lower end of the Rettbergsaue between Wiesbaden-Schierstein and Mainz-Mombach, which the Rhine flows around on both sides . In addition to the bridges Theodor-Heuss-Brücke and Weisenauer Brücke ( A 60 ), which are located further upstream, it is the third road crossing of the Rhine near Mainz and Wiesbaden .
The entire structure will be built as two bridges, each with three lanes for one direction of travel. The western bridge is temporarily under traffic with two lanes in each direction. The eastern bridge is under construction.
The old Schiersteiner Bridge was completed in 1962 and dismantled from 2017.
Jurisdiction
Since the largest part of the bridge is in Hesse and the smaller part in Rhineland-Palatinate, the Hessian state administration alone takes care of the maintenance of the Schiersteiner Bridge due to an agreement made years ago between the two countries. The task falls under the responsibility of Hessen Mobil - Road and Traffic Management in Wiesbaden. The Rhineland-Palatinate state administration, on the other hand, is solely responsible for the Weisenauer Bridge . This is also clear from the names of the bridges. Schierstein belongs to Wiesbaden (Hesse), Weisenau to Mainz (Rhineland-Palatinate).

Bridge from 1962
The 1282 meter long bridge consisted of six partial bridges (100 meters of which were made of prestressed concrete ), was built from 1959 to 1962 and had a combined cycle and footpath on both sides. Approximately in the middle there was a staircase up the Rhine that gave pedestrians access to the Rettbergsaue island, but this path had already been closed since autumn 2013 due to the construction of the Schiersteiner Bridge.
history
The first requirement plan for the federal trunk roads in 1956 included, among other things, the Mainz – Wiesbaden ring road with the construction of the Rhine bridges Wiesbaden-Schierstein, Mainz-Weisenau and the Main bridge Hochheim . The planning for the Wiesbaden-Schierstein Rhine bridge began in 1955. It was forecast 7100 vehicles per day; 23,000 vehicles per day were considered possible. The planning approval decision followed on July 13, 1959. The building design was drawn up by the Leonhardt and Andrä office in collaboration with Louis Wintergerst. On September 28, 1959, the Düsseldorf steel construction company Hein Lehmann AG was awarded the contract for the superstructures. With a special proposal from Hellmut Homberg, it improved the cross-section and saved 23% of the steel mass compared to the administrative proposal. A total of 7,895 t of structural steel were required for the superstructures and the entire structure cost 32 million DM .
Bridge course
The Schiersteiner Brücke begins shortly after the Wiesbaden-Äppelallee motorway junction on the Hessian side and crosses the Rhine. In order to avoid height differences, the bridge on the Rhineland-Palatinate side was extended beyond the Mainz-Mombach junction as a nearly one kilometer-long Lenneberg overpass. A bridge structure with 31 fields was built, which spans the Mombacher Oberfeld and connects the Rhine bridge with the high terrace on the Lenneberg ( Mainz-Gonsenheim , near the nature reserve Mainzer Sand ). As a result, the Mombach junction is one of the few that is on a bridge.
The bridge was originally built for a federal road leading over it, so that there are only very short acceleration and deceleration lanes at the junction in question . However, several lighting systems were installed to illuminate the connection point. For cost reasons, however, these remained dark and were dismantled on the western side at the end of April 2013. There were also two traffic control systems at AS Mombach , but these have also been out of service (around the end of the 1980s) and have now been dismantled.
The A 643 is missing between the AS Gonsenheim and Mombach hard shoulder , which inevitably leads to traffic jams even in the event of small traffic accidents or car breakdowns , as around 80,000 vehicles roll over the bridge every day. It is the last bridge above the Middle Rhine to the south bridge 85 kilometers down the Rhine in Koblenz .
Two spiral staircases gave pedestrians and cyclists access to the left and right of the bridge. In addition, on the eastern side there is the possibility to get to the Rettbergsaue via a suitable stairway in summer. Due to the construction of the Schiersteiner Bridge, this route has been closed since mid-August 2013. Due to the lowering of the lane in February 2015, both spiral staircases had to be demolished, and the western spiral staircase on the Schierstein side was also demolished. Both paths have been closed to pedestrians and cyclists since February 2015. A new access route is to be built on the east side soon (as of April 2015).
Technical specifications
The overpass consists of six individual bridges. The first structure, following on from the Mainz-Mombach junction, which is designed as a bridge structure itself, is the Mombach flood bridge, a two-span composite bridge with a length of 46.4 m + 52.2 m = 98.6 m. The next structure is the small river bridge, a haunched steel bridge with three fields and 70 m + 170 m + 70 m = 310 m in length. This is followed by the three-span Rettbergsau flood bridge over a Rhine island, a composite bridge with a constant construction height that is 3 × 70 m = 210 m long. The fourth structure is the large river bridge over the right arm of the Rhine, a three-span haunched steel bridge with a length of 85 m + 205 m + 85 m = 375 m. The subsequent flood bridge Schierstein is again a composite bridge with a constant construction height and (70 m + 60 m + 55 m =) 185 m length. After a 4.39 m wide separating pillar, a prestressed concrete bridge with a length of 3 × 32.88 m = 98.64 m follows .
Redevelopment
From 1997 to 2000 the steel , composite steel and prestressed concrete structure was repaired for DM 21 million . The road surface of the bridge between Mombach and Schierstein , along with the two-wheeled and pedestrian path on both sides, was completely renewed. According to an expert opinion from 2006 on cracks in the orthotropic carriageway slab , the structure is no longer suitable for renovation and a provisional remaining useful life until 2015 was determined. As a result, the bridge has to be checked for possible damage every six months. In Germany, bridge structures are normally subjected to a simple inspection every three years and a major inspection every six years. A new construction of the Schiersteiner Bridge was planned.
Due to the poor state of construction, the previously existing speed limit was reduced from 100 km / h in late summer 2006 to 80 km / h. Since spring 2007 it has been further reduced to 60 km / h between the Mombach and Äppelallee junctions. Since August 21, 2007 there has also been a large sign on the Wiesbaden side in the direction of Mainz: You drive above, we are building below. Therefore 60 km / h , as no construction site can be seen from the road. On March 7th, 2008, the same sign was put up on the Mainz side just before the Lenneberg high street. Since September 19, 2008, the speed has been controlled by a permanently installed speed camera on the Wiesbaden side in the direction of Mainz. No fixed system is planned on the opposite side, but there are still often mobile radar stations here.
In addition, the responsible State Office for Roads and Transport has set up a website with current information. Since then, the entire length of the bridge, including the Lenneberg high road, has had a top speed of 60 km / h.
Blocking the bridge
On February 10, 2015, at around 10:00 p.m., significant damage was discovered after construction work had been carried out on the new bridge piers for the construction of the Schiersteiner Bridge nearby. One pillar of the approach bridge had inclined 20 cm, causing a bearing to jump out and the roadway to sink by about 30 cm. This caused cracks in the bridge. The bridge was closed immediately.
As a result of the closure, there were significant traffic restrictions in the entire Mainz / Wiesbaden region. The Theodor-Heuss-Brücke between the Wiesbaden district of Mainz-Kastel and the city center of Mainz is not designed for this volume of traffic. The next high-performance bridge upstream is the Weisenau bridge on the A 60 , 11 km away ; downstream, this is the south bridge on the 327 federal road in Koblenz, 84 km away .
On April 2, 2015, the superstructure of the damaged Mombach foreland bridge was successfully raised to its original position with a total of 20 presses between 8 a.m. and 4 p.m. in two-centimeter steps. In the days that followed, the remaining crack widths (greater than 0.4 mm) were mapped and grouted. A final test loading took place on April 10th. The bridge remained closed until the end of the 2015 Easter holidays and was reopened for vehicles up to 3.5 tons on the evening of April 12th. To determine the cause of the damage, the Rhineland-Palatinate State Mobility Agency commissioned the WBI engineering office for foundation engineering and rock construction to prepare an expert report. The report comes to the conclusion, “(...) that the construction of the GEWI piles caused loosening in the subsoil, which led to subsidence below the foundation of axis 33 east and, as a result, to the inclination of the foundation and column, which in turn led to the observed bearing and bridge damage. "

Limited use of the bridge
After the bridge had been lifted into its original position, after subsequent load tests on the evening of April 12, the bridge could only be released for vehicles up to 3.5 tons and a maximum width of 2.2 meters. A complicated warning system, which includes weight sensors , barriers and warning lights, is intended to prevent vehicles that exceed the maximum size and / or weight from crossing the bridge. A truck driver tried to cross the bridge on the night of April 12th and 13th, 2015. The warning system could stop him, however. He was escorted from the highway by the police. In the first two days, more than 70 trucks over 3.5 tons tried to drive on the bridge anyway. On the Wiesbaden side alone, the barrier closed over 400 times by the beginning of May and 310 parking tickets were issued.
At the beginning of August 2015, the Hessian Ministry of the Interior announced that the "bridge watch" by the Hessian police costs around 3700 euros a day or around 110,000 euros a month, as there are almost 2000 official hours for the deployment, with four officers from Monday to Friday at the time from 6:30 a.m. to 7:00 p.m. and with two officers from 7:00 p.m. to 6:30 a.m. as well as on weekends and public holidays. The Rhineland-Palatinate Ministry of the Interior does not name any costs and announced:
“In Rhineland-Palatinate, such costs are not recorded by police operations. It is a very specific task of the police, for which no costs - for example, as for operations around football matches - are charged "
The bridge was opened again on November 7, 2015 for truck traffic up to 40 tons.
Dismantling
The dismantling began in November 2017 immediately after the new downstream bridge had been released. The part of the bridge over the Rhine was lowered onto a pontoon ship on February 27, 2018 and is to be dismantled on land.
Landmark
On the old bridge there was a boundary stone with the coats of arms of Rhineland-Palatinate and Hesse , which was made in 1961 by Raimund Eser . It was donated by the Wilhelm Dyckerhoff Institute , Wiesbaden. The boundary stone was moved to the new bridge in winter 2017.

New building from 2013
The new bridge is planned with two separate superstructures, each 21.72 meters wide and designed for three lanes and one hard shoulder as well as one cycle and sidewalk. First, a superstructure is to be built on the downstream side of the existing structure. After its completion, the old bridge will be demolished and then the second superstructure will be built on the route of the existing structure, partly using the old foundation. The distance between the bridges on the Mainz bank side is determined by the predetermined position of the carriageway crossing of the existing Mainz-Mombach departure ramp and is 18.75 meters there. The distance decreases to the north.
Meadows in the Mombacher Rheinufer nature reserve (it has an area of 0.355 km 2 ) are used, among other things, for white storks as feeding biotopes. There is no reliable knowledge of any damage to the animals due to the construction work.
A realization competition was held for the new bridge. In December 2007, first place was awarded to a design by a joint venture between the engineering office Grontmij BGS and the architectural office Ferdinand Heide . This provides for a 1285 m long box girder bridge with partially haunched box girder cross-sections .
According to the planning, the actual construction should start in May 2013. The planning approval decision for the new construction of the Schiersteiner Bridge was signed by the Hessian Transport Minister Dieter Posch on January 5, 2012, and by the Rhineland-Palatinate Infrastructure Minister Roger Lewentz on March 2, 2012. As a preparatory measure for the planned construction of the downstream bridge, the first clearing work was carried out in March 2012 in the area of the Schiersteiner Kreuz . On June 7, 2013, the award of the contract for the new construction of the Schierstein Rhine Bridge with an order value of around 173.4 million euros (excluding VAT) was announced.
The new building officially started with the groundbreaking on September 12, 2013. After the construction site had been set up, the foundation work for the new bridge piers began in October 2013. This work was planned until the beginning of 2014. 800 cubic meters of concrete are used for a pillar as a support for the steel superstructures. In the course of 2014, the assembly of the steel superstructures began. The downstream section should actually be completed by mid-2016, after which the demolition of the existing bridge and the construction of the second section should begin. The lowering of the bridge pier in 2015 has delayed this measure, so that the completion date 2020 was targeted in March 2017. Since November 20, 2017, traffic has been rolling over the new half of the bridge in both directions. At the turn of the year 2021, the fourth and last prefabricated bridge section is to be "floated in" on the south side. Hessen Mobil expects that the bridge can be opened to traffic in 2021.
The construction of the bridge was delayed by a decision by the red-green state government in Rhineland-Palatinate ( Cabinet Beck V , Cabinet Dreyer I ) to design the bridge with four instead of six lanes, while the black and yellow state government in Hesse ( Cabinet Koch III , Cabinet Bouffier I ) stuck to the six-lane expansion. The delays have been criticized as "small stateism". On the basis of this and other examples, the Federal Investment Commission recommended that the Länder should be deprived of responsibility for motorway construction and that this should be centralized. The coalition agreement for the formation of the next government ( Dreyer II cabinet ) returned to the six-lane expansion.
Info center
In December 2014, an information center was opened on the Schierstein side near the port on the grounds of the RWZ concentrate plant Wiesbaden . The visit is possible after registering with Hessen Mobil .
Trivia
In the Mainz carnival campaign 2015, even before the Schiersteiner Bridge was completely closed, Nick Benjamin dedicated a song to the ailing bridge with Der Brigg ist nedd gut .
In addition to regional SWR television , 3sat also broadcast a detailed report on the Schiersteiner Bridge and the damage to the economy resulting from the closure in spring 2015 in its business magazine Makro .
Another bridge over the Rhine, which is closed to heavy goods traffic over 3.5 tons, is the Leverkusen Rhine bridge on federal motorway 1 .
