In early March 1945, German forces in France and the Low Countries were flooding back across the Rhine with American forces in close pursuit. Hitler intended to use the swift, deep, and wide Rhine River as a moat to stop the Allies while he concentrated on defeating the Russians in the East. He ordered all […]

LEVERKUSEN, GERMANY-  There is a growing theory regarding bridge building which states: build one that lasts 100 years and requires no maintenance. This demand is especially high in the United States and therefore, the focus of bridge construction has come down to cable-stayed suspension bridges, suspension bridges, girders and slabs. Sadly though, this theory always gets rebuked when one needs to look at the increasing number and size of vehicules crossing them, plus the need to maintain them on a yearly basis to ensure that this utopian goal is realized.

With the Motorway Crossing in Leverkusen (known as the A1 Rheinbrücke), the bridge is overtaxed with vehicles and despite extensive maintenance, the state of North-Rhine Westphania, together with the cities of Leverkusen and Cologne are now working on a replacement bridge. Built in 1965, the bridge features a cable-stayed suspension design, using one set of towers and cables in the middle of the roadway with cables anchored in two different lines supporting the median, which supports a steel deck girder roadway that supports the Motorway A1. The bridge was built by Hellmut Homberg, who was the Othmar H. Ammann of bridge building, having built several crossings in the Rhine-Ruhr River regions, including structures in Duisburg, Bonn, Cologne and Emmerich. The longest suspension bridge in Germany was built in Emmerich and is credited to Homberg. The A1 Rheinbrücke provides direct service between Saarbrücken to the south and places to the north, which includes Münster, Bremen, Hamburg, Lübeck and two-lane to Fehmarn.  The crossing is one of the oldest of its modern type, even though records showed that a tunnel and a basket-weaved tied arch bridge were also on the table (note: The latter can be seen in the Fehmarn Bridge, as reference). The bridge has a total length of 1061 meters; the main span has a length of 280 meters. The width of 31.7 meters includes the expansion of its original four lanes to six in the mid 1990s.

Originally slated for replacement in 2025, construction of the bridge is currently in the preliminary stages with plans to have a new structure in place by 2020. The reason: Because of the increase of traffic, both on the bridge as well as underneath with ships travelling along the Rhine,  combined with weather extremities, structural weaknesses, especially in the steel, has become so great that rehabilitating the bridge has no longer become an option.  Patchwork and weight limits have been conducted on several occasions, but only for the purpose of prolonging the bridge’s life until its new structure is open to traffic and the old one is removed.

Already a new bridge is designed and crews are doing soil samples to determine where to place the bridge. German public TV channel WDR (based in Cologne) is doing a documentary on this bridge project in the form of Sendung mit der Maus, a TV program for children and families with a lot of interesting facts and experiments. Televising the document in irregular intervals since January 2016, one can see how bridges are inspected, planning is undertaken for constructing the bridge, and the actual project itself. One can have a look at the progress below, but ask yourself this question:

Do you agree with this design preference? If not, how would you go about with this project if you are the planner, engineer and city official?

The Autobahn 1 is one of the oldest motorways in Europe, and the third longest motorway in Germany behind A3 and A7. The Weimar Republic proposed building a highway without intersections and traffic lights during the 1920s, yet was realized through massive construction efforts during the time of the Third Reich. The A1 was presented in 1939 but serving the Rhine-Ruhr region, as well as in segments to the north. The rest of the autobahn was completed in the 1960s and later expanded in the 1990s and 2000s. The last segment at Fehmarn is being fought by locals because of the negative environmental impact on the island through a new crossing between the island and Schleswig-Holstein as well as between the island and Denmark. The battle is ongoing and one can read more here.…..

 

The Rheinbrücke in Leverkusen is one of several bridges of its kind that have been targeted for deficiencies. Two other cable-stayed bridges in Duisburg and Cologne (Severin Bridge), plus the Köhlbrand Bridge in Hamburg are having the same structural issues because of too much traffic and are facing the same fate as the crossing in Leverkusen.

Book/Documentary of the Month: A Tour of the Rhine in NRW

There are many ways to write a book on bridges, let alone do a documentary for a TV program. One can focus on one bridge and its history, but that is more for locals who are closely attached to the bridge. One can focus on a region with a handful of bridges, like writing about bridges in a county or district. Again, the main focus would be the locals, but it would draw some attention from other bridge enthusiasts. As the region gets bigger, so do the number of people who are closely tied to the bridges, and the people from outside who are interested in these sturctures.

However, if you want to focus on bridges along the river, like we have here along the Rhine River, this is where one has to be walk a fine line. While documentaries like the one televised by German Public TV Station WDR can draw hundreds of thousands of viewers to the region, one has to be careful that the people do not become bored with each and every single bridge that is documented and told in the language that everyone can simply understand. This does not mean that it is impossible to talk about a tour of bridges along the rivers. The problem is when the length of the rivers are longer and there are more crossings, then one really needs to divide the project into segments dealing with region, history and in a certain degree, importance to the community.

One of the most successful projects is a two-volume book written by a former Iowa teacher, Mary Costello, on the bridges of the Mississippi River. Her book featured sketches of bridges she drew while on tour and some history to each one, yet it was divided unto the bridges along the Lower Mississippi (Gulf of Mexico to Iowa) and the Upper Mississippi (Iowa to Lake Itasca, Minnesota, where the river began). But what about another long river, the Rhine River?

For 1200 kilometers (or 760 miles), the Rhine starts in the Swiss Canton of Grisons in the southeastern part of Switzerland in the Alpine region and makes its way north, forming borders with Liechtenstein and Austria before entering Lake Constance and forming the border with Germany. After Basel, the river creates a border between the Bundesrepublik and France before flowing into Germany after Karlsruhe. After passing through Mannheim, Mainz, and Frankfurt, the river creates a deep gorge which slithers its way from Bingen to Bonn and later through the industrial metropolises of Duesseldorf, Cologne and Leverkusen.  After turning west from there, it enters the Netherlands, where after passing through Rotterdam and Utrecht, it creates a delta where the river empties into the North Sea near Katwijk.  Nearly 100 bridges cross the Rhine, half of them in Germany. Each of them has a history of its own, not only in terms of its design and construction, but also its involvement in history.

When WDR (an arm of Berlin-based German public TV channel ARD with its branch office in Cologne) produced the two-part documentary on the Rhine River crossings in 2010, it was aware of the fact that it had to narrow its focus to only a few bridges, for each one had its own personal history to it, and the broadcasters there were aware that they could not afford to lose their audience with too many bridges, nor get into conflict with other German public TV stations who could benefit from this experience, like HR, which covers Hesse and Rheinland Palatinate and SWR, which covers the Saarland and Baden Wurttemberg. Therefore, WDR focused its bridge documentary on just the bridges in North Rhine-Westphalia, covering the bridges of Cologne, Duesseldorf and Duisburg.

The End Result?

A two part series where the first part focuses on the historical aspect. The story there starts in 1945 where the Nazis, in a desparate attempt to fend off the Allied Troops that were enchroaching the country, blew up any bridges along the Rhine that were not destroyed. Yet the mission was unsuccessful because of one of the last standing bridges at Remagen, the Ludendorff Railway Bridge, which the Americans captured on 7 March, 1945. Yet the bridge collapsed 10 days later but not before the troops constructed the bridge heads on both sides of the Rhine so that they could construct a pontoon bridge in its place. The original bridge heads were kept in place and is now a memorial.

The bridges laid in ruins together with the cities that were bombed out. Yet, one bridge, the Hollernzollern Bridge was rebuilt, using the through arch spans that were bombed off the piers and were sitting in the Rhine. Originally consisting of two three-span arch bridges, an additional one was added in the 1950s and today is the key link for trains travelling to Frankfurt and points to the east of Cologne Central Station. The Bridge serves as a symbol of love, as the railings are covered with padlocks with signs of love written all over them. Legend has it when lovers meet, the padlock was locked on the fenced railing with the keys thrown into the Rhine.

But the first part also featured a tour of the bridges, inspected by the city engineer on a regular basis to determine how stable the structure is and what repairs are recommended. Marc Neumann, the city engineer serving Cologne provided a tour of the inside portion of the Zoo Bridge in Cologne, one of the most heavily traveled vehicular bridges in Cologne that was built in 1962 and is a box girder bridge, the first built in Germany at that time. Other highway bridges in Cologne have dealt with problems with increased traffic and the city has desperately tried to keep up the pace by constant maintenance of the bridge, as shown with the Severin Bridge, a cable-stayed suspension bridge that was the first post-war modern bridge built over the Rhine in Cologne. The 1959 structure was the focus of structural issues with its stayed cables, which needed to be replaced with the rest of the bridge being painted lime green afterwards. The purpose: to protect the bridge from the salt and other debris that have a potential to make the bridge rust and corrode.

The second part of the series focused on other bridges in the state. Apart from the ones at Remagen, there were many cable-stayed and steel arch bridges that were mentioned in the documentary. While the Theodore Heuss Bridge, built in 1957, was the first cable-stayed suspension bridge built in Germany, there are two bridges are worth mentioning: The Bridge of Solidarity in Duisburg and the Oberkasseler Bridge in Duesseldorf. The Oberkasseler Bridge was built in 1973 replacing an ornamental arch bridge built in 1909 that was structurally deficient. The bridge was built alongside the old structure on the south end and after the old bridge was razed, the entire cable-stayed bridge featuring a set of towers planted in the middle of the roadway, was moved 47.5 meters to the original location of the 1909 bridge, a feat unimaginable for a bridge of that size and length, at 617 meters.  The Bridge of Solidarity in Duisburg was built in 1950 replacing a similar bridge built in 1936. Yet the name stamms from a group of protesters who blocked traffic to the bridge to protest the closing of a steel plant nearby. From 10 December, 1987 until 20 January, 1988 the workers walked the picket line on the bridge and the nearby company they had worked, resulting in the state government discussing about the crisis in the steel industry and the bridge being renamed at the request of the protesters. A unique action that one can rarely see today unless one is in southern Europe protesting the European Union’s bailout package with the conditions, as seen in Spain, Greece and Cypern.

The Rhine Bridges in North Rhine-Westphalia are unique in a way that one has to go beyond the appearance of each structure to look at its history, how they were built and rebuilt, and how they are integrated into the lives of the people today. While focusing on safety and history were the key elements of the document series, the report also looked at how the people and their bridges go together, whether it is a person living inside a bridge or if there are musicians performing inside or underneath the bridge- both were found at Zoo Bridge in Cologne. The Rhine bridges in North Rhine-Westphalia, once a pile a rubble because of the war, are now a part of the lives of the residents who use it regularly to get from point A to point B. And even if we are in the post-modern era where sleek modern designs dominate the land and cityscapes, the memories of the bridges, how they looked like in the past and how they look like now will remain in their memories for generations to come.

With this in mind, I would like to close with a couple questions for the forum, and for those interested in producing a thorough and history and culturally enriched documentary similar to what was produced by WDR on the Rhine Bridges of North Rhine-Westphalia. The documentary covered many key points that were important for people to know about bridges, infrastructure, safety, culture and history, giving them some interest and perhaps an incentive to pursue something that is similar to what was shown on TV. But the questions posed here are something different from what was profiled here. Keeping the documentary in mind:

1. How would you do a documentary on bridges along the river? Would you chop the river up into segments or keep it the same? Which aspects would you include?

2. When looking at the documentaries enclosed below (in German), what is your opinion of the documentary? What words of advice would you give to people wanting to do what WDR did with the Rhine? This applies not only to the Rhine itself but other rivers.

3. Which other rivers would you imagine doing a documentary on apart from the Rhine and Mississippi Rivers?
