Wolkenburg Suspension Bridge: A Unique Cable-Stay Along the Mulde

wolkenburg2

Wolkenburg (Saxony)/ Limbach-Oberfrohna/ Glauchau- The last of the three bridges profiled here that is debuting along the Zwickauer Mulde is the Wolkenburg Suspension Bridge. Before going further with this bridge, we need to clarify what this bridge looks like as well as its aesthetic value. The current structure, open since May Day this year is actually a cable-stayed suspension bridge, a bridge type where suspenders actually support the roadway from the tower. When looking at them from an American’s point of view, cable-stayed bridges are bland in appearance, ranking them up there with concrete slab/girder bridges that represent a sour taste to the land-/ or even cityscape. This can be best exemplified with two bridges that come to mind: The Fort Steuben and the Russell-Ironton Bridges. Both of them spanned the Ohio River; both of them have the characteristic A-frame tower, whose cables support the roadway; both of them replaced historic bridges that had a lot of characteristic and aesthetic appeal but were neglected by the department of transportation in a successful bid to have them replaced. Both of them have been demolished, leaving nothing but documentation on websites owned by James Baughn and Nathan Holth, respectively. Both bridges are prone to having problems in the short-term involving the cables and the roadway because, like other modern bridge types, there is too much (heavy) traffic using it. We’re even seeing it with a pair of bridges in Germany, which will be mentioned later on.

But while these cable-stayed bridges are being looked down upon like the other concrete spans in America, pursued by Donald Trump and Elaine Chao with some statues of Paul Ryan and Mitch McConnell and a new quasi-national flag of the US (sorry, I have to be sarcastic with this analogy), cable-stayed bridges in Europe, from an outsider’s point of view, can be viewed as a treat, especially for pedestrians and cyclists using them while on the bike trail. One in three cities in Germany has at least one of this type. And while there are some standard examples that exist, most of the cable-stayed bridges we find here are designed in such an unusual way, that they are screaming for people to stop by to pay homage; whether it is because of tilted towers, curved or even rounded roadways, ….

or in the case of this bridge, a single tower that is leaning outwards towards the river bank, whose primary cables- all draped over a pointed tower- are supporting the deck. The deck itself has a pony girder approach span with a Warren pony truss main span that crosses the Zwickauer Mulde.

The bridge replaced a century-old structure that consisted of a wire suspension bridge, going by the textbook guidelines that were created by another German engineer, John Roebling. Roebling’s concept was strands of thick wire that were spun together to create the main cables that were anchored between the towers and the ground anchors on shore. The best examples of his design were the Cincinnati-Covington Bridge (1869) and the Brooklyn Bridge (1883, though he died during its construction). The original Wolkenburg Bridge featured heavy cables  combined with vertical suspenders that supported the narrow walkway. The walkway itself was fenced with heavy wire but not trussed like one will see in many suspension bridges today, such as the Golden Gate Bridge or the suspension bridges in New York designed by Othmar H. Ammann.

 

Flooding in 2013 caused extensive damage to the bridge’s roadway and cables to a point where officials in Limbach-Oberfrohna, where Wolkenburg is part of the conglomerate, as well as local officials decided to demolish the bridge, including the tower, which was arched and made of concrete. It took more than three years, combined with lots of money and politicking before the conglomerate let the contract to the firm of Iroplan, based in Chemnitz, and its architect, Klaus Lenz, to build a new bridge at the site of the old one.

 

Construction started in 2016 with the leaning tower and foundations. The roadway was assembled offsite, featuring sliding and welding connections, judging by the author’s observations during his visit. The roadway was lifted into place by crane in November that year, and after attaching the cables between the tower and the roadway, the bridge was completed. What was not completed at the time of the visit in March were the roadway leading to the bridge, the dike to keep the water in the river, and painting the bridge. The bridge was still grey and silver.  The cost for constructing the 80 meter long and two meter wide cable-stayed bridge was 1.2 million Euros.

After many delays and headaches, people have their bridge back. At the May Day opening, where many people participated, mayor Jesko Vogel led the opening with a bang, as cannons were fired and a historic theater group from Glauchau were on hand for some entertainment. Refreshments were provided by the fire department. While the suspension bridge will forever be in the memories of many who live in Wolkenburg, this bridge reopens a connection between Eichenwald Forest and the mill area, both are northeast of the historic city center. The bridge will be a new icon  for Wolkenburg, providing a picturesque view from the historic city center and its churches and castle on the hill. And contrary to common belief regarding cable-stayed bridges, the Wolkenburg Suspension Bridge serves as an example of a bridge of this kind that, if designed with a good aesthetic taste, can be used for any form of traffic,

 

even if this bridge is open for pedestrians and fishermen only.  😉

BEST KEPT SECRET TOUR GUIDE:

US:

The Bridges of Boone County, Iowa– Minus the now removed Wagon Wheel Bridge, this county is rich with history involving its bridges, one of which involved a hero who averted a potential disaster in Kate Shelley.

The Crossings along the Chesapeake-Ohio Canal– Built in 1828, the canal system serves four states and provides water to Washington. It also features some of the oldest arch bridges in the country, some of which have been restored since 2005.

The Arch Bridges of Cowley County, Kansas– Until this year, 17 arch bridges served the county, most of which were built between 1890 and 1920 and made of stone. One of the bridges succumbed to flooding this spring.

The Bridges of Cincinnati/ Covington– Several bridges, big and small, old and young can be found in this metropolis, including John Roebling’s suspension bridge built in 1869, one year before his death on the Brooklyn Bridge.

The Bridges of Washington County, Maryland– 22 historic stone arch structures span Conococheague Creek and Antietam Creek, and its tributaries, including Wilson’s Bridge, a 210-foot long bridge built in 1819. Most of the structures are almost 200-years old.

The Bridges of Tompkins County, New York– Over two dozen bridges are found in this county that are historically significant, including their centerpiece, the Newfield Covered Bridge.

International:

Glauchau (Saxony)– Several arch bridges span the Mulde as well as on the hill leading to the castles. As a bonus, a covered bridge and an iron bridge can be found here.

Zwickau (Saxony) – It is extremely rare for a town to have a 500-year old covered bridge with a very unusual design, a cantilever pony truss bridge and an unusual through truss bridge in a community, but Zwickau has that and more.

The Canal Bridges of Brugges (Belgium)– several stone arch bridges span the canals serving this historic community.

Calgary, Alberta– Two dozen bridges, modern and historic serve this Canadian community including those on the city’s historic registry.

The River Tyne- Flowing through Newcastle and Gateshead, this river features 22 improtant bridges as it flows into the North Sea from the eastern UK.

The Bridges of Newark on Trent– Like Glauchau, Newark has 27,000 inhabitants and a wide-array of well-known bridges- ten of them.

The Bridges of Dublin, Ireland– Many bridges from different periods of time can be found here. This includes a pair of cable-stayed bridges, three arch bridges and a couple truss bridges.
