Blackfriars Street in London, Ontario reopened to traffic after five-year closure and one year extensive restoration work.

LONDON, ONTARIO (CANADA)- At 225 feet (68.6 meters), it is the longest bowstring arch bridge in the world. It was one of the longest ever built by the Wrought Iron Bridge Company in Canton, Ohio At 143 years of age, it is one of the oldest historic bridges of its kind left in Canada and North America. It is one of the rarest bridges to find in the country because of its dwindling numbers. And now, after five years including one year of a complete restoration, the Blackfriars Street Bridge in London, Ontario is back in business.

Thousands convened to the bridge on December 1st to commemorate the reopening of this unique bowstring arch bridge, located at Blackfriars Street, spanning the North Branch of the Thames River connecting Blackfriars Park on the west bank and Harris Park on the east bank. This included a ribbon-cutting ceremony followed by a parade of cars that crossed the newly restored structure.  The cost for the complete restoration was $8.6 million, which was split between local and federal funding. For many residents and bridge enthusiasts, it is a relief to have the structure back in service while at the same time, retain its historic and cultural integrity. Many have had great childhood memories of the bridge and were happy to see the bridge open to traffic. From its build date of 1875 until its closure in 2013, the bridge served vehicular traffic before structural deterioration forced its restriction of the bridge to solely pedestrian cyclists in 2013. In November 2017, the bridge was lifted off its place, cut in half, then dismantled to be transported to an offsite complex where it was sandblasted and welded, with several parts being replaced.

This bridge restoration was met with hefty criticism, especially from bridge preservationists who dubbed the Blackfriars Street Bridge Restoration as a complete replacement. In a statement posted by Nathan Holth in the historicbridges.org homepage, “A 2018 rehabilitation project essentially replaced nearly every surviving piece of original material on this bridge with new material that looks completely different than the original design.” Holth added that “this may be due to a lack of sufficient consultation with experts in bridge restoration, or a lack of open minds on the part of engineers who may have consulted with experts in bridge restoration.” And while the website acknowledged that rehabilitation was needed, this type of work was more of a modernization of the bridge than in-kind restoration, stating “with an in-kind restoration, many parts of the bridge would still have been replaced, but they would have been replaced with replicas of the original design. The bridge’s bowstring trusses today are almost unrecognizable.”

While his claim is that with the complete replacement of bridge parts with new materials is as bad a bridge replacement, one needs to look at the difference between the Blackfriar’s Street Bridge before and the structure after the replacement to see the difference. It is clear that the portal bracings and the upper chord are different; the portals veered away from its three-tiered Lattice and X-frame portal bracings with heel bracings and was replaced with simply the X-frame with heels, whereas the original beams with Phoenix columns have been replaced with rectangular beams, much of the vertical and diagonal beams appear to be the same. One needs to have a look at the bridge for himself to see the difference.

Nevertheless, inspite of the criticism, the restoration of the bridge and its reopening of the crossing will provide drivers, cyclists and pedestrians alike with an opportunity to gain access to the university complex on the western bank of the Thames from the greenery area on the east side, where the two branches form the Thames. But most importantly, the City of London got back their beloved historic bridge, one of only a handful of historic landmarks left for the city, but one of the most important that a person should see when passing through. This is one that is not only in the running for this year’s Ammann Award in the category of Best Example of a Restored Historic Bridge, but one on the places to visit list for many, like myself, who have yet to see the structure and judge for himself how much alteration was actually done.

The Blackfriars Street Bridge has its own Twitter website, where you can follow up on the bridge and read the stories behind the structure and the love affair the people have with the longest bowstring arch bridge in the world. Click here and follow for details.

bhc tribute new

Author’s update: Funeral Arrangements are being planned for historic bridge preservationist Eric Delony, who died on October 23rd. According to Information from Christopher Marston, it is being scheduled for January 2019. When and where has yet to be determined, but the Chronicles will inform you in due time as soon as everything is finalized.

Mr. Marston, who worked with Eric for many years, write a much-detailed version of the obituary, honoring him for his three decades-plus work in documenting and saving historic bridges, much more than what the Chronicles covered when having honored him with the Ammann Awards for Lifetime Achievement. This was done in 2016. With his permission, the detail of his life and work are written below. More Information on him and the stories behind his historic bridge preservation will follow. For now, enjoy reading about Mr. Delony from Christopher’s point of view:

Eric N. DeLony, who served as Chief of the National Park Service’s Historic American Engineering Record (HAER) from 1987 to 2003, died on October 23, 2018, after a long struggle with Alzheimer’s disease. Over his career, Eric became known as a pioneer in historic bridge documentation and preservation and one of the nation’s leading experts in historic bridges. In recognition of his achievements, Eric was the recipient of the 2000 General Tools Award, the highest honor bestowed by the Society for Industrial Archeology.

 

Early Years at HAER

After graduating from the Ohio State University in 1968, Eric was first hired as a summer architect on the New England Textile Mills Survey, a joint project of the Smithsonian (under the leadership of Robert Vogel) and the Historic American Buildings Survey (HABS). The following year he became a member of the Mohawk-Hudson Area Survey, HAER’s very first field team. This ambitious project documented several industrial sites and bridges in the Albany area, and team members were challenged to devise new recording techniques for manufacturing and engineering structures. His detailed drawing of the Troy Gasholder remains the logo of the Society for Industrial Archeology to this day. Once he completed his Master’s in Historic Preservation at Columbia University under James Marston Fitch (where he first met his lifelong friend and colleague, preservation educator Chester Liebs), Eric was hired as HAER’s first full-time employee in 1971. HAER began recording a variety of bridges and other industrial structure types as part of state inventories and themed surveys. These included surveys of the Baltimore & Ohio and Erie railroads, Paterson and Lowell mill towns, and later mining, steel, power, and maritime-related sites, among others. Eric also helped initiate “SWAT teams” to record endangered structures prior to demolition. By 1987, Eric DeLony had been promoted to Chief of HAER.

 

HAER Historic Bridge Program

In collaboration with Emory Kemp of West Virginia University, Eric began developing the HAER Historic Bridge Program in 1973, which would become the first comprehensive national program to identify and protect historic bridges. Through Eric’s efforts, HAER developed partnerships with the National Trust for Historic Preservation (NTHP), the Advisory Council on Historic Preservation (ACHP), and state historic preservation offices (SHPOs). The first goal of the program was to promote comprehensive historic bridge inventories in each state. When inventories were required by law in 1987, Eric’s initiative became a catalyst in making highway bridges the first class of historic structures to be nationally evaluated.

After the preliminary state bridge inventories were completed, HAER partnered with state departments of transportation (DOTs) to undertake HAER summer documentation projects that would more intensively document representative bridges, with the first taking place in Ohio in 1986. Using funding from a variety of partners like the Federal Highway Administration (FHWA), DOTs, and historic groups, HAER recording teams collaborated with national and local experts to produce large-format photographs, histories, and drawings of hundreds of historic bridges in Arkansas, Illinois, Iowa, Massachusetts, New York, Ohio, Oregon, Pennsylvania, Texas, and Washington, from 1987-2001. Eric also worked with engineering professors such as Dario Gasparini at Case Western, Stephen Buonopane at Bucknell, and Ben Schafer at Johns Hopkins to hire students to compile detailed engineering analyses of a variety of historic bridge types, going beyond traditional architectural history reports. In appreciation of Eric’s initiatives, the White House and ACHP presented HAER’s Historic Bridge Program with a National Historic Preservation Award in 1992.

In addition to the nation’s highway bridges, the historic roads and bridges in the National Park system were also deteriorating from neglect and overuse. HAER developed a pilot project in the National Capital Region of the National Park Service (NPS) in 1988 to survey the historic and significant transportation-related structures and designed landscapes at various NPS units. With support from FHWA and NPS, this program expanded in 1989 and continued until 2002 to document the roads and bridges of large western national parks, national battlefields, and eastern parkways. HAER also partnered with New York and Connecticut to record several historic local parkways. The drawings of these projects are compiled in America’s National Park Roads and Parkways: Drawings from the Historic American Engineering Record (Baltimore: Johns Hopkins, 2004).

Eric DeLony was also influential in HAER’s involvement with a third major initiative involving FHWA and historic bridges. Realizing that covered bridges were a beloved but endangered resource, Vermont Senator James Jeffords proposed legislation to save them. The resulting National Historic Covered Bridge Preservation (NHCBP) Program was established by FHWA in 1998 as part of the TEA-21 transportation bill. HAER received research funding beginning in 2002 to document the nation’s most significant covered bridges, as well as developing other educational initiatives including engineering studies, a traveling exhibition, national conferences, and National Historic Landmark nominations. With the benefit of continued FHWA support, HAER Project Leader Christopher Marston has continued Eric’s vision and is in the process of finalizing several research projects. These include the 2015 publication Covered Bridges and the Birth of American Engineering, co-edited with Justine Christianson, and dedicated to Eric DeLony. Rehabilitation Guidelines for Historic Covered Bridges will be published later in 2018.

 

Nationwide Advocacy

Eric was a longtime member of the Society for Industrial Archeology (SIA) and developed the SIA Historic Bridge Symposium beginning in the early 1980s to allow experts to share research and preservation experiences. Eric attended his last one in 2011; the 25th was held in 2016 in cooperation with the Historic Bridge Foundation in Kansas City, Missouri. He was also an active participant with the Transportation Research Board (TRB)’s Committee on Historic Preservation and Archaeology in Transportation (ADC50) beginning in the 1990s, which was comprised of professionals from state DOTs, SHPOs, and consultants involved in preservation issues on federally funded transportation projects. Research and best practices on preserving and maintaining historic bridges was always a major focus of the committee. As a subcontractor to Parsons Brinckerhoff, Eric DeLony co-authored A Context for Common Historic Bridge Types with Robert Jackson, for the National Cooperative Highway Research Program (NCPRP Project 25-25, Task 15) in 2005.

Not satisfied to just record historic bridges, Eric was also determined to see as many bridges as possible saved and preserved. Some of the projects that Eric championed included: the 1828 Blaine S-Bridge and the 1868 Zoarville Station Bridge in Ohio; the 1869 Henszey’s Bridge in Pennsylvania; and the 1858 Aldrich Change Bridge in New York. As Ohio DOT’s Tom Barrett reflected, “Through Eric’s encouragement, I feel that the historic bridge inventory in Ohio has stabilized and improved in many ways. We strive to explore all plausible alternatives to demolition and find ways to educate everyone on proper rehabilitation and design solutions. Hard-fought successes here and nationwide in bridge preservation will always be a part of Eric’s legacy.”

Eric’s advocacy extended beyond bridges to roads as well. As Preserving the Historic Road conference founder Paul Daniel Marriott stated, “Eric appreciated that roads and bridges were intertwined. He was one of the first people to acknowledge that historic research and advocacy [were needed] for historic roads. Eric DeLony was instrumental in establishing the historic roads movement.”

 

International Influence

Eric studied at Ironbridge with Sir Neil Cossons in 1971-72 as a Fulbright Scholar, and this experience led him to encourage collaboration between HAER and industrial archeologists and preservationists in Europe and other countries. Eric consistently hired International Council on Monuments and Sites (ICOMOS) foreign exchange students for his summer field teams beginning in 1984.

He represented the United States at several meetings of the International Committee for the Conservation of the Industrial Heritage (TICCIH). He also worked with several prominent European scholars, such as Barrie Trinder at Ironbridge and Louis Bergeron at Le Creusot, on various publications, exhibitions, and conferences. Another issue that Eric championed has finally shown dividends; after several decades, the U.S. delegation finally nominated the Brooklyn Bridge as a UNESCO World Heritage Site in 2017.

 

Post-career Legacy

After retiring to Santa Fe, New Mexico, in 2003, Eric became a bridge preservation consultant. Maintaining “The Pontists” email list, he advocated for various bridge preservation causes and initiatives, and continued to write and teach.

An avid collector of rare books, technical reports, and images of historic bridges, Eric donated his collection to two prestigious archives. The “Eric DeLony Collection of the History of Bridges and Bridge Construction” was established in 2010 at The Huntington Library in San Marino, Calif. In 2013, the Linda Hall Library in Kansas City, Missouri received the “Eric N. DeLony Engineering & Bridge Collection.”

After health issues removed him from public life, Eric continued to receive various honors acknowledging his legacy. Beginning in 2014, David Wright of the National Society for the Preservation of Covered Bridges established the Eric DeLony Scholarship, an annual prize awarded to a college student interested in historic preservation. Eric was also a recipient of the 2016 Othmar H. Amman Award for Lifetime Achievement from The Bridgehunter’s Chronicles.

Eric DeLony was truly a pioneer in the world of historic bridge documentation, preservation, and advocacy. The 3,000+ bridges in the HAER Collection at the Library of Congress, and hundreds of examples of preserved historic bridges across the country are all a testament to his lifelong determination and passion for saving historic bridges.

Wilischthal Viaduct Renovated and In Service

bhc newsflyer new

ZSCHOPAU (SAXONY), GERMANY-  Four kilometers to the south of Zschopau in the village of Wilischthal, deep in the valley of the river that bears the same name as the city of 9,600 is a piece of artwork that most recently got a much-needed facelift. The Wilischthal Viaduct was built in 1901 and features a series of different arch types. The main span is an open-spandrel arch bridge which stretches 31 meters across the River Zschopau.  The three approach spans, each of which are over 10 meters, spans a rail line connecting Annaberg-Buchholz with Riesa and Chemnitz on the east side next to the main highway, S228, a state highway. The entire bridge was built using natural stone, taking well over a year to build. It was open in 1901.  For 10 years, the bridge had been open for only one lane of traffic. Now the bridge has been reopened to traffic and two cars can meet from each direction. Furthermore, pedestrians can cross it without any hindrance.  According to news story from the Chemnitz Free Press, bridge was rehabilitated at the cost of 1.3 million Euros ($2.1 million) and included replacing the decking with a wider one (the original deck width was 6 meters; the new one is now three meters wider) and installing beautiful blue railings. Furthermore, the arches were strengthened to accomodate heavier loads. All of the renovation work lasted two years and it included partial and full closures, thus making access to nearby villages  Gelenau and Scharfenstein difficult.

Nevertheless, the renovation was worth it during my visit at the bridge. There will be more photos of the bridge to come as the tour guide on the bridges in Zschopau is being made, but the whole bridge itself looks just like new.

And for a 117-year old bridge, this IS telling. 🙂

Saving the Bockau Arch Bridge Day 9: Concrete Bed in the River

44070908_2103392739691364_1800512296926052352_o

AUE (SAXONY), GERMANY-

A first in the Bockau Arch Bridge series since July and a lot has changed since then. It goes beyond the change in the color of the leaves in the fall, as you can see from the picture of the trees flanking the Zwickau Mulde from the old bridge.

43828446_2103386639691974_1526001072814948352_o

It goes beyond the fact that workers have poured the concrete on the new structure built adjacent to the old bridge. This was done in August and according to latest news from the Chemnitz Free Press, the new B-283 Bridge is scheduled to be open to traffic by Christmas, thus ending the detour of Highway B-283 between Aue and Eibenstock in the western part of the Ore Mountains, which has until now been rerouted through Zschorlau and Schneeberg.

It has to do with a finding that was discovered during our most recent visit to the bridge and our Friends of the Bockau Arch Bridge Association Meeting on October 9th, something very unpleasant and will most certainly cause legal action because of the violations committed. Despite many headaches trying to download this clip from my camera, this 5-minute film tells all, even without the commentary in English…..

And after crossing the old bridge to get to the Bockau side of the span, we could see the “Schandfleck” in detail. A total “Schande” (shame) because of several reasons!

44060604_2103398859690752_1463759733906210816_o

43878102_2101490776548227_3880232661054128128_n

According to several sources, the old bridge is supposed to remain in place until it is demolished and removed in the spring in 2019 with a pair of very important exceptions:

1. Since the bridge is still protected by the Denkmalschutzgesetz (German Culture Heritage Law), documentation of the structure will need to be carried out before its removal, which includes ist history, description and historical significance to the Region. If following the Guidelines that exist in the USA, that process could take 1-2 years to complete.

2. The Investigative Committee (Ausschuss), located in the state parliament in Dresden, which took on the petition to save the bridge back in March, has yet to decide on the bridge’s fate. At the present time, the association has three possible suitors that are willing to take ownership of the bridge once the new B-283 Bridge is completed. If Dresden says yes to the proposal, then the association has until March to name the suitor willing to take over ownership of the old bridge. If not, then the green light will have been given to proceed with the removal.

3. Even if Dresden says no, a copy of the Petition was forwarded to Berlin; specifically the Deutschen Bundestag (German Parliament) and the  Deutsches Nationalkomitee für Denkmalschutz (Geman National Committee for Cultural Heritage), for the bridge carries a federal highway and if therefore responsible for the ownership of the bridge, which is still protected by the Cultural Heritage Laws (Denkmalschutzgesetz). That Petition has been accepted and the bridge is being considered for a program to protect places of interest, thus providing funding for restoring and repurposing the bridge.

Having the concrete bed in the river, according to multiple choices may have violated these agreements and then some, for the Zwickau Mulde is protected by several natural preserve laws on both the state and federal levels. With the concrete bed in the water and despite the two pipes running underneath, it will have the potential to hinder the flow of fish flowing downstream, which could cause unrest from some of the local fisheries and fishing clubs along the river.  Despite the need for having the bed there for the eventual removal of the old bridge, having the bed there is too early and could possibly cause some violations that could result in some legal actions.  A gallery with pictures taken by the author will provide you with some Details.

To summarize, the old bridge is still standing and can be crossed despite being partially blocked off. Yet the concrete bed indicates that workers want to go ahead and demolish the bridge before Christmas. The new bridge is almost completed and will open between November and December. The fate of the old bridge falls in the hands of both Berlin and Dresden, yet as the bridge is the ownerhship of the federal government, Berlin will have a say, yet if and how the old bridge can be saved is still open. There are interested parties in owning the bridge but the group cannot push forward until the government has a say in the whole debacle. And even if the group gets the go ahead, the decision of who owns it has to be made before spring 2019. And even then, funding will be needed to rehabilitate and restore the bridge.

In other words, one has to happen after another in sequential order, yet some people are trying to make haste by putting the carriage before the horse- meaning tear the bridge down before the ownership transfership is approved and inspite of violations they make be committing.  This mentality is clearly American and has been the target of comments by the German far-right party AfD to compare modernization in Saxony at the cost of historic places of interest to the works of the Taliban in Afghanistan. This commentary, albeit very harsh, is not far from the truth, and should the old Bockau Arch Bridge come down too prematurely, it may serve as a basis for more voters to flock to the AfD and for the current government in Saxony to topple come the state elections in 2019. If the party uses the slogan “Remember the Rechenhausbrücke!” similar to the Alamo in Texas, the people in Saxony will understand why.

Rebuilding the Blenheim Covered Bridge- a PBS Documentary

202806pv

The Blenheim Covered Bridge in New York State is one of a few covered bridges that deserves attention because of its unique design. Built in 1855 by Nichols Montgomery Powers, the 232-foot long bridge is a Long through truss bridge with a single gable supporting double barrels. Even though the bridge was modified four times, the last being 1897, the wooden bridge remained in service until 1932 when it was bypassed by a newer bridge. It remained in place until it became victim of Hurricane Irene on 28 August 2011.

Seven years later and with the help of bridge building experts, planners and restorators, the Blenheim Covered Bridge is back in service after two years of a painstaking task to rebuild the structure from scratch. The American public TV provider PBS produced an episode from the NOVA series on this project entitled Operation: Bridge Rescue. There, the nearly hour-long documentary focuses on the reconstruction and relocation of the covered bridge to its final resting place where it can be used again after 87 years of no service.  While a preview of the program can be seen here, a link to the entire program can be found at the end of the article. Enjoy the film and think of some other covered bridges that deserve to be reconstructed for reuse. You may have ideas yourself. 😉

Iron Bridge Reopens After Six Months

42193689_2073408586023113_3282565340222980096_o

Century-old, two span pedestrian bridge to be part of new bike trail.

bhc newsflyer new

AUE (SAXONY), GERMANY- Back in March of this year, many hikers were irritated with the fact that their favorite crossing over the Zwickau Mulde, connecting Bad Schlema with points to the east and south, was closed to all traffic. They were forced to take a detour 3-4 kilometers away or even ditch the notion of going by foot and driving by car. Since the beginning of this month, the Iron Bridge has been in use again, six months after it was closed to traffic. The two-span Parker bowstring arch bridge spans the Zwickau Mulde and was built in 1900, replacing a covered bridge that was destroyed in a flooding. And while the truss superstructure remains the same as is, some work was done on the bridge to ensure that it is safer for use, even for cyclists. For instance, new railings were installed to ensure that no one falls off the bridge. At 1.5 meters high, they are 0.5 meters higher than the originals. Furthermore, new acorn-colored varnished wooden decking replaced the previous one that was developing cracks and dry-rot after years of extremities due to weather. The decking is thicker and will be able to withstand stresses caused by increased in traffic by bikers and pedestrians.

IMG_20180920_185258634

The rehabilitation is part of the project to construct the Mulde Bike Route, taking it off its current path that shares a street connecting Bad Schlema and Aue and running it along the river. At the same time, the Carlsbad Route is being extended, which will cross the bridge and end at Bad Schlema at the railway station. Currently, the bike trail starts in Carlsbad (Karoly Vary in the Czech Republic), and after going through the mountains and over the border at Johanngeorgenstadt, joins the Mulde Bike Trail at Wolfsgrün and terminates in Aue.  Despite the completion of the rehabilitation, which costed approximately 430,000 Euros, the realignment of the trail, combined with a new bridge over the rail-line Zwickau-Aue, a new picnic area on the eastern side of the Iron Bridge and the rehabilitation of the Stone Arch Bridge at Bad Schlema will delay the completion of the entire project until 2020, at the earliest.  Therefore the bridge will continue its local traffic until then, and people will have to put up with vehicular traffic along the original route along the Mulde.

The Chronicles will continue to keep you posted on the latest regarding the project.
