Author’s note:This is the first podcast since the move and features all the events that happened over the past 2-3 weeks. The most current version of Newsflyer (for the week of August 5th, 2019) will follow.
Lansing, Michigan- Entries are still being taken for this year’s annual Iron and Steel Preservation Conference. The two-day event will take place on Friday and Saturday, October 18-19 at the Lansing Community College West Campus, located at 5708 Cornerstone Drive in Lansing. With a couple exceptions, this conference has been held annually and focuses on welding and other industrial techniques, using historic bridges as examples, as the state has many of them still in use, a third of which have been credited through the technical expertise of those who have participated in the workshop and has done a lot of work with historic bridge preservationists and welding experts.
The events on each day will be from 8:00am to 5:00pm. According to the coordinator, Vern Mesler, the Conference will feature the following:
Day One of this conference is primarily lecture, and Day Two participants will have opportunities to see Demonstrations of actual preservation techniques and have hands on learning opportunities.
Day 1 – Speaker’s Forum: Presentations on the rehabilitation work recently completed on Michigan’s Cut River Bridge on U.S. Highway 2 in the Upper Peninsula by Michigan Department of Transportation personnel who were directly involved in the rehabilitation work. (Lloyd Baldwin, cultural and historic resource coordinator for MDOT, will lead these sessions from the initial planning stages to the completion of the rehabilitation work.)
Presentations on issues related to riveted and bolted connections and on the damaging effects of pack rust on metal structures. Presentations on the role of riveting in new construction and design.
The presenters at the Friday event:
Lloyd Baldwin, Cultural and Historic Resource Coordinator (MDOT)
“Cut River Bridge Rehabilitation”
Andrew Zevchak & Mario Quagliata (MDOT)
“Bridge Rehabilitation Design Overview”
Christopher Garrell, PE (AISC)
“Exploiting the Resiliency of Built-up Steel Members”
Robert J. Connor, PhD (Purdue University)
“Research and Evaluation of Pack-out Corrosion in Steel Built-up Members at Purdue University”
Steve Howell, Ballard Forge
“Hydraulic riveting introduction”
Steve Howell and Lansing Community College Staff
“Hydraulic Rivet Demonstration”
Day 2 – Hands On Demonstration: The experienced staff of craftsmen at Lansing Community College will demonstrate electric arc welding processes, braze welding, and an introduction to the industrial rivet process (both field riveting and shop hydraulic riveting).
The event is open to all who are interested in the profession of welding and/or preservation of historic bridges and workshop participants will experience the use of the aforementioned welding demonstrations and other industrial processes during hands-on sessions and learn how these processes are used in the preservation of historic metals and new construction. One of the key centerpieces of this conference will be the Cut River Bridge along US Hwy. 2, which had recently undergone extensive rehabilitation using these welding techniques that will be presented at the conference (for more on the bridge, please click here).
Breakfast and lunch will be provided for both days. Participants will need to book their own lodging accomodations. For more information and to register for the event, please click on the link below, which will lead you directly to the conference website and registration page:
Following up on my last Pic of the Week post, we have this week’s pic which is symbolic. With this bridge, I completed my series on historic bridges that were built along the Motorway 72 between Hof (Bavaria) and Chemnitz (Saxony). Consisting of the Koditz, Pirk, Pöhl, Reichenbach, Wilkau-Hasslau and this last bridge, the Friesenthal Viaduct located in the south of Plauen west of the exit Plauen-Ost, all six bridges were built between 1935 and 1940, of which half of them were left uncompleted for many years and it wasn’t until 1990, when the Motorway 72 was fully restored that it became a fully-functional throughway, where to this day, tens of thousands of cars, trucks and other utility vehicles use this mainly four-lane expressway, crossing these six viaducts and dozens of overpasses daily.
This last bridge I photographed has a unique story and some primary concerns on top of that. To better explain the bridge’s story, I produced a video with some commentary, which you can listen and watch here:
The 57th pic of the week takes us to the second to last bridge I photographed along the original Motorway A 72 between Chemnitz and Hof (the last one will come in the next pic). This one is located east of Plauen and has a unique history. The Pöhl Viaduct is a seven-span stone arch bridge that was built from 1937 until its completion in 1940. The 232-meter long viaduct once spanned the valley of the River Pöhl near the village that bore that name, as well as the neighboring villages of Altensalz and Neuensalz. What was once a viaduct spanning a valley became a viaduct spanning a lake, as the Pöhl Reservoir (in German: Talsperre Pöhl) was created in 1964. The project took seven years and included the relocation of residents from Pöhl, the dredging of the valley and lastly, the construction of the dam on the north side of the reservoir as well as two dams and locks at Alten- and Neuensalz. This pic was taken from a boat, as we were on a boat tour along the Reservoir. The viaduct is difficult to photograph due to a lack of access from land. Therefore, it is recommended to spend 13 Euros and enjoy the boat tour that lasts an hour and gives you a brief look at what a person can find along the Reservoir. After all, one will never get an opportunity to photograph a bridge crossing emerald green water.
By the way, where did that emerald green water come from, anyway? 🙂
: The Reservoir Pöhl can be accessed by exiting either Treuen or Plauen-Ost. The area provides great opportunities to go swimming, (sail-)boating or hiking. There are many campgrounds nearby where one can camp while enjoying the views.
Arguably one of the most beautiful bridges in Japan, the Kintaikyo Bridge (錦帯橋). Famous for its beautiful wooden structure of 5 arches held by stone pillars taking you across the Nishiki River (錦川).
Although it is a pedestrian bridge, you are required to pay a small fee to cross over. I didn’t know this when I arrived and all set to go full blast with my camera, the lady on the right hand side at a wooden small booth greeted me and asked for 300 yen in exchange for a round trip ticket.
The reflection of the bridge on the waters is like a piece of art itself. On the river there was a crane! Difficult to see in the 8th pic, but it’s there! Because I arrived later in the evening just before the sun was setting, the ice cream shop called Musashi I wanted to…
To honor the reopening of a key historic icon, this Pic of the Week takes us back ten years and to Winona in Minnesota. During my visit in 2010, I took a ton of photos of the Winona Bridge, a 1942 cantilever through truss bridge that spans the Mississippi River at the Minnesota-Wisconsin border, carryinh Highway 43. While I got a lot of angles and listened to some interesting stories about the bridge, including one from a gas station attendant who used to be a female wrestler (she even looked like one of my heroes, Sara Del Rey), this shot from the Wisconsin side was probably the best one of the bunch. Even with the new bridge running alongside the newly restored historic bridge, this photo vantage point would be highly recommended if you want to get a shot of just the cantilever bridge itself, even when lit with LED at night.
