The Mittelland Canal ( MLK ) is a federal waterway and with a length of 325.3 kilometers, it is the longest artificial waterway in Germany. Including branch and connecting canals, the length is 392 km. It connects the Dortmund-Ems Canal with the Weser , Elbe and Elbe-Havel Canal . In a broader sense, it is part of a connection between the Rhine and the Oder . In the west, the connection to the Rhine is established via the Dortmund-Ems Canal and the Rhine-Herne Canal or the Wesel-Datteln Canal . In the east, the Elbe-Havel Canal, Untere Havel Waterway and Havel-Oder Waterway connect the Mittelland Canal with the Oder. In a European dimension, it enables a connection between the Netherlands, Belgium, Luxembourg, France and Switzerland on the one hand with Poland and the Czech Republic on the other.

The canal is also known under the names Ems-Weser Canal, Weser-Ems Canal, Weser-Elbe Canal, Rhine-Elbe Canal, Elbe-Weser-Ems Canal or Ems-Weser-Elbe Canal . These are old or regional names that are rarely used.

course

Crossing the Weser

The Mittelland Canal branches off from the Dortmund-Ems Canal at the Nassen Dreieck near Bergeshövede in Tecklenburger Land , runs through the Gravenhorster Gorge and leads north of the Teutoburg Forest and the Wiehen Mountains to the east. The Osnabrück canal branches off to the south near Bramsche , which leads to the ports of the city of Osnabrück .

In Minden the Mittelland Canal crosses the Weser valley at the Minden waterway intersection . The canal crosses the Weser in two structures, so-called trough bridges . There is a connection to the Weser via the connecting channel north and the shaft lock or the connecting channel south with the two locks of the industrial port. South of the Schaumburg Forest and the Steinhuder Sea , the route continues to Seelze near Hanover , where the Leine Valley is crossed in an old and a new journey. There is a connection to the Leine and Ihme via the Hannover-Linden branch canal and the connecting canal to the Leine . In the further course the MLK crosses the northern districts of Hanover and then meets the Anderten canal level. The distance up to this point is referred to as the western section and is at a level of 50.3  m above sea level. NN . At this level, the line has a connection in the Dortmund-Ems Canal to the south as far as the Münster canal level.

To the east of Anderten the apex position runs 14.70 m higher at 65  m above sea level. NN through Peine and Braunschweig . Shortly after the junction of the Elbe Lateral Canal , it ends at the Sülfeld canal stage in Wolfsburg . This lowers the canal level by 9 m.

From here the east end runs at a height of 56  m above sea level. NN further through Wolfsburg, right along the Volkswagen factory. The canal leads over the former German-German border and through the Drömling Nature Park , past Calvörde , Haldensleben and Wolmirstedt .

North of Magdeburg, the canal crosses the Elbe in the 918 m long Magdeburg canal bridge and shortly after it reaches the Hohenwarthe canal stage . Here the east end ends and the canal is lowered by 18.55 m to the level of the Elbe-Havel canal. East of Hohenwarthe, the MLK merges into the Elbe-Havel Canal at km 325.7, which continues the MLK kilometering to km 380.9 at the confluence with the Untere Havel waterway .

Construction and history

Planning and start of construction

In 1856 there were first plans to build a shipping canal from the Rhine to the Elbe in the North German Plain north of the low mountain range threshold . The idea was developed with the help of the district master builder von Hartmann. The hydraulic engineer Leo Sympher had proven the profitability of such a project in calculations, planned a route and later also managed large parts of the construction work.

The project was bitterly debated in the Reich, as the East Elbe agrarians feared that cheap products would penetrate from the West (" sewer rebels "). As a compromise, the canal, the construction of which was decided when the Prussian Water Act of April 1, 1905, came into force, was only to be built as far as Hanover. In the following year, the first construction phase from Bergeshövede to Hanover began, providing a connection to the Dortmund-Ems Canal in the west. The First World War delayed further construction noticeably, but the section to Minden, at that time still under the name Ems-Weser Canal, was completed and put into operation in 1915. A year later, the canal bridge over the Weser near Minden was completed and the canal was driven to Hanover and Misburg harbor as an eastern end; the compromise solution was thus completed.

A northern connection was planned from 1919 with the so-called Hansa Canal . The Hansa Canal should branch off from the Mittelland Canal in Bramsche , cross the Weser at Achim and reach the Elbe at Stade . The project was not carried out.

Inauguration of the Hindenburg lock in Anderten (1928)

On July 26, 1926, the completion of the Mittelland Canal was decided in a state treaty.

As early as December 14, 1918, the Prussian government ordered a section from Anderten to Peine, including the branch canal to Hildesheim, as part of emergency work. Some of the work began immediately after the war and was completed in 1928 with the opening of shipping on the Mittelland Canal from Hanover to Peine and the branch canal to Hildesheim. The Anderten lock was inaugurated in Hanover by Reich President Paul von Hindenburg in 1928.

In 1928 the next expansion of the canal began in an easterly direction. The port of Peine was connected in 1929, and the port in Braunschweig was connected in 1933. With the help of the Reich Labor Service , the moorlands in the southern Altmark were drained and in 1938 the connection to the Elbe was completed with the completion of the Sülfeld lock and the Rothensee ship lift (opening ceremony on October 30) near Magdeburg. However, the Elbe overpass was no longer successful due to the Second World War, and construction work on the canal bridge over the Elbe and the Hohenwarthe ship lift ceased in 1942. During the time of the division of Germany, the construction of the Elbe crossing was no longer pursued. Ships had to take the detour via the descent to the Elbe and the Niegripp lock in the Elbe-Havel Canal , which continues to the east .

The so-called "south wing of the Mittelland Canal" was also not completed. This project, decided in 1926, which was to be implemented at the same time as the expansion of the Mittelland Canal, envisaged the construction of several canal sections in the Leipzig / Halle area in addition to the expansion of the Saale - this would have provided a direct shipping connection from the Ruhr area via Magdeburg to the Central German industrial area. The work, which began in July 1933, made rapid progress at first, but was slow from 1937 at the latest and was finally stopped completely in 1942/43 due to the war (→ Elster-Saale-Canal ).

Towing monopoly

In 1905 the Prussian Landtag decided to introduce the towing monopoly in the law on the creation and expansion of waterways. This meant that only the state monopoly tugs were permitted on the canals in the western Prussian provinces. In February 1915 operations between Bergeshövede and Minden were started by the Minden towing office and in December 1916 between Minden and Hanover by the Hanover towing office . On December 31, 1967, these services were discontinued, the "self-propelled" had prevailed.

Expansion and dimensions

History of the expansion

Crossing under the A 2 and turning into the
Hannover-Linden branch canal
New and old canal bridge in Minden

On the Bergeshövede – Hanover route, the canal route was designed for 600-t ships, but the option has already been provided to make the canal passable for 1000-t ships by raising the water level by 50 cm. To the east of Hanover, the Mittelland Canal was dimensioned for the 1000 t ship.

From the 1950s onwards, self-propelled motor ships completely displaced tugboat shipping, and the ever larger ships made an expansion inevitable. In 1965 it was decided to expand the MLK for the Europaschiff (1350 t, length 85 m, width 9.5 m, draft 2.5 m), corresponding to the waterway class IV at the time. During the expansion, the ship sizes continued to develop, so that the large motor cargo ship (2300 t, length 110 m, width 11.40 m, draft 2.8 m) became the assessment basis. Based on the canal cross-section for the European ship, the standard profile that is still valid today was developed in 1994; it corresponds to today's waterway class Vb.

In the area of ​​what was then the GDR, sections of the route were expanded between 1976 and 1987. However, these routes did not meet today's requirements, so that the entire eastern line was expanded as part of the German Unity Transport Project No. 17 . In 1993 the construction of a new security gate at Haldensleben began and in 1997 construction began on the Rothensee lock. A year later, the crossing of the Elbe valley near Magdeburg began with the construction of the Magdeburg canal bridge. In 1999 the foundation stone was laid for the Hohenwarthe lock. In 2003, with the inauguration of the Magdeburg waterway intersection and the Hohenwarthe lock, the Mittelland Canal was completely passable for the first time. The diversion via the Rothensee lock, the Elbe and the Niegripp lock, which had been necessary until then, was history.

A connection between the canal and the Twentekanal in the Netherlands is also being discussed, which would shorten the route to the port of Rotterdam considerably, but the profitability of the project is questionable. [5]

In the first years of expansion, long stretches of rectangular profile with sheet piling were built . For reasons of animal welfare, these stretches had to be fenced in afterwards in order to prevent animals from drowning. That is why the trapezoidal profile is preferred today. Sheet pile walls are only used in the area of ​​ports or locks. If the use of sheet pile walls is unavoidable in the open, for example due to lack of space on the Hanover city line, the combined rectangular-trapezoidal profile (KRT profile) is used. With the KRT profile, the vertical sheet pile wall ends about 20 cm below the water surface. This enables small animals to leave the water.

Standard cross-section

The profiles mentioned are combined with one another in many places: for example, a trapezoidal profile on one side and a rectangular profile on the other, or the sheet pile wall ends below the surface of the water and merges into a sloping slope. This results in different water level widths.

Rule ship

  • Large motor goods ship , also large motor ship (GMS): length 110 m, draft 2.80 m, width 11.45 m, carrying capacity 2300 t
  • Oversized motor ship (üGMS): length 135 m
  • Push convoy : length 185 m, width 11.40 m, draft 2.80 m, deadweight 4500 t

Branch channels

The Mittelland Canal has an inexpensive longitudinal profile with only three canal steps along its entire length. This would not have been possible if the canal had been led directly through Osnabrück, Hildesheim and Salzgitter. Instead, these cities were connected to the main canal via branch canals. An exception is the Ibbenbüren branch canal , which was created in the course of the expansion of the main canal. The expanded MLK received a new route over a length of four kilometers. The old route was abandoned from the east in order to connect the Ibbenbüren loading point. As federal waterways, the branch canals are legally part of the Mittelland Canal.

Waterway crosses and connecting canals

Along its course, the Mittelland Canal crosses the Weser, the Leine and the Elbe alongside some small rivers. The canal is led in trough bridges over these federal waterways and connected to the crossing river by connecting canals , also federal waterways. In Minden and Magdeburg one speaks of waterway crossings . The connecting channels branch off directly from the main channel. The connection channel to the Leine is an exception, it branches off from the Hannover-Linden branch channel. The connection canal south to the Weser and the Rothenseer connection canal also establish the connection to the local ports.

Locks and boat lifts

The Mittelland Canal was originally designed for tug shipping. That is why the locks in the main canal and in the branch canal to Salzgitter were built so large that they could accommodate an entire towing formation. For this reason, these old lock structures meet today's requirements in length and width. Only the clearance height had to be adapted to the current conditions, for example in Anderten and in the Salzgitter branch canal in Wedtlenstedt and Üfingen . In Sülfeld, the south lock was replaced by a lock with a larger passage height and jamb depth . The smaller locks in the branch and connecting canals will be replaced by larger ones with a length of at least 139 m in the next few years - this is what happened with the lock in Bolzum in the Hildesheim branch and the Weser lock in Minden in the north connecting canal to the Weser.

Security gates

Security gate on the Mittelland Canal in Havelse

In order to largely prevent the leakage of water in the event of damage to the canal bed and thus the flooding of the surrounding area, nine security gates have been installed between the Dortmund-Ems Canal and the Elbe : at the beginning of the canal at Bergeshövede, on both sides of the branching off of the Osnabrück canal, to divide one longer embankment stretch near Herringhausen , west and east of the Minden waterway intersection and the canal overpass over the Leine and at the beginning of the long embankment stretch to the Elbe near Haldensleben.

Crossings with traffic routes and waterways

The Mittelland Canal and its branch and connecting canals required the construction of 45 railway bridges, 314 road and road bridges and 9 underpasses. In addition, there were 245 culverts (underpasses under pressure) and culverts (with a free water level) at the intersection with bodies of water.

The Mittelland Canal mainly serves to transport goods, but from the beginning it was also assigned water management tasks. This includes the provision of water for industry and agriculture and the drainage of floods from intersecting small rivers and streams into the Weser or Elbe. The canal is constantly losing water through evaporation, seepage and lock operation. The water level is also influenced by strong winds. In the canal, which runs mainly in an east-west direction, strong westerly winds can raise the water level at the ends of the canal supports by 40 cm. In order to ensure that the passage heights and water depths remain as constant as possible for shipping, the water level must be constantly regulated.

The regulation of the water supply of the Mittelland Canal and its branch canals is controlled centrally by the district and operations center in Minden. There are numerous pumping stations, relief systems and measuring points available between Bevergern and Hohenwarthe for this purpose.

Since the few natural tributaries are insufficient to constantly supply the canal with water, water usually has to be pumped from the Weser and Elbe into the canal bed. The pumping stations for supplying the Mittelland Canal with new water are located in Minden on the Weser and in Magdeburg at the Rothensee lock. There are also pumping stations at all locks that pump the water into the higher reaches.

Another water supply is sporadically via the Aller reliever at Grafhorst . The 3 km long canal was created to drain the previously notorious Aller floods. In the 1960s, this discharge was operated so intensively that hardly any water flowed from its source area in the Aller.

Almost the entire Mittelland Canal has an accompanying service route on at least one bank. This is released for pedestrians and cyclists at their own risk. The paths are mostly paved with fine gravel, and often paved or paved in the area of ​​locks or port facilities. With the exception of the driveways and the lock areas, there are no significant gradients. This makes it possible for the untrained to cover long distances. In some places the bank has to be changed over a bridge, for example at port facilities. In some cities (such as Hanover) the canal and its banks also function as a local recreation area.

The canal is a diverse sailing area for water sports enthusiasts. There are numerous yacht clubs as well as canoeing and rowing clubs on the Mittelland Canal and its branch canals. In the Osnabrück, Minden, Hanover, Haldensleben and Magdeburg area, passenger ships operate according to the timetable.

Due to the territorial reform of 1974, the city ​​of Langenhagen lost its function as a port city ( Brinker Hafen ) and its location on the Mittelland Canal over a distance of 700 m.
