Street View, Jun 2021

Southern West Virginia Online posted four photos with the comment:
The Kanawha Falls Bridge has now been closed for nearly eight years…
The bridge was shut down in November 2018 after a structural failure caused part of the bridge deck to drop about five inches. Inspections later uncovered additional deterioration and structural concerns. 
Today, the nearly century-old bridge across the Kanawha River remains closed to traffic.

"Significance: This bridge is an unusual example of an ornamental reinforced concrete bridge, and the first bridge designed by the noteworthy engineer, Benjamin C. Gerwick, who received patents for pre-stressed concrete construction and a caisson foundation solution in bridge construction. It also exemplifies the movement away from metal truss bridges by county highway departments towards a preference for concrete bridge construction during the early decades of the 20th
century." [HAER_data]

"Reinforced concrete bridges first came to national attention as the result of a presentation by Fritz von Emperger, an Austrian civil engineer, at the meeting of the American Society of Civil Engineers in April 1894 at New York City. American engineers met von Emperger*s remarks with skepticism. Concrete commonly was used for bridges in France and Germany, but its use in bridge construction was not generally accepted in the United States. Americans doubted whether the available materials of the 1890s and the slender, flat concrete bridge design used in Germany suited the extreme climates of North America. Yet, as the 1890s progressed and the twentieth century began, a number of bridge builders, including several in Ohio, dared to use concrete. Those first concrete bridges spurred an increase in the popularity of concrete bridges in America. The improvements of reinforcing steel and concrete aided the acceptance of concrete bridges by Americans. An Ohio company, Buckeye Portland Cement Company, stands among the earlier developers of improved materials and its success is partially responsible for an early 2 acceptance of concrete bridges in Ohio."

1993 Modern Truss Bridge


Aug 2026. These would be the same rain storms that caused flooding on I-70.

Looking East:
Street View, Apr 2025

Looking East with the inclusion of the flood gate. We can see the floodwall in the corner of the video screenshot, so it is looking East. Since the water is flowing to the left in the video, it is going North. I followed Moxahala Creek north to determine that it dumps into the Muskingum River just south of Zanesville. Muskingum River goes south to the Ohio River. So the heavy rains in Ohio State, plus the record flood rains in Indiana on the White and Whitewater Rivers, are going to the Ohio River. But I haven't seen anything about the Ohio River flooding.

Looking West to verify that the west side has a levee while the east side doesn't.

Both sides of the Moxahala Creek are in Roseville, OH.

And both sides of the bridge are in Muskingum County at 1st Street.

So the difference in levee protection is not because of the tax base. I looked closer at the street views, the difference is that there is a river bank on the west side and the east side is down in a flood plain.

I was disappointed that Bridge Hunter did not have an entry for the truss bridge. I understand that modern girder bridges are not worth noting. But I think any truss bridge is worth noting. If anything, modern truss bridges are more worthy because they are now so seldom built. 

I noticed that the weight limit between the street views of Apr 2025 and the video of Aug 2026 has been significantly reduced. I wonder what is wrong. When I Googled "roseville ohio truss bridge" I got the Athens Road Bridge. But a satellite image shows that it has been replaced with girder bridge. Street views show it was replaced between May 2012 and Aug 2021. So I still don't know what is going wrong with the 1st Street Bridge that has caused the need for reduced weight limits.

1870,1938 Main Street Bridge and 1810 Red Mill Dam on South Branch Raritan River in Clinton, NJ

Dam: (Satellite)

I added the label "metalIron" because the bridge is made with iron instead of steel. In fact, it uses cast iron as well as wrought iron. But cast iron can be used only for the compression members. Since this is a Pratt truss, the top chords and verticals are cast iron.

The Lowthorp Truss Bridge represents an early type of iron truss that dominated bridge construction from the 1850s to the 1870s. Fabricated in 1870 by William and Charles Cowin of Lambertville, New Jersey, the bridge follows the Pratt configuration in the arrangement of its trussing members. It is of composite construction, with all compression members made of cast-iron and all tension members made of wrought-iron. In the Pratt truss, the vertical posts and horizontal upper chord are in compression and are made of cast-iron; the diagonals and bottom chord are in tension and are made of wrought-iron. Cast-iron members and lower chord connections are based on truss bridge patents received by Francis C. Lowthorp of Trenton, New Jersey, during the 1860s and 1870s?
After 1870, engineers and fabricators favored bridges made exclusively of wrought-iron, as this material performed equally well whether subjected to tensile or compressive stresses. After 1890, wrought-iron was supplanted by the stronger material steel. Lowthorp Truss Bridge, one of few known surviving examples of this type, is representative of the short-lived era (20 years) of composite cast and wrought-iron bridge construction. The Lowthorp Truss Bridge has been in service for over 100 years with only minor modifications, thus attesting to the soundness of its design, quality of craftsmanship and care of maintenance.

Nathan gives this bridge a rating of 10+10.

A waterwheel without a flume looks naked. I am glad they added the waterwheel because that visually transforms an old building into a mill even if the top of the waterwheel is above the dam. The photo below by Manuel shows that the mill actually used a turbine.

This must have been part of the limestone quarry operation.

And these metal parts were obviously part of the mill. This confirms that the waterwheel we see today is just decoration. The mill used a turbine.

They evidently turn the mill into a haunted house for Halloween.

1967 Mississinewa Dam on Mississinewa River near Peru, IN

(Satellite)

This is one of three flood control dams (JE Roush, Salamonie, and Mississinewa Lakes) built in Indiana to stop storm water from flowing into the Wabash River during a storm. After a storm passes and the Wabash River returns to a more normal flow, they release water from the reservoirs. While releasing the water, the flow in the Wabash River is comparable to what it is during a rainstorm.

Mississinewa Lake, U.S. Army Corps of Engineers, Chicago District posted
📣 UPPER WABASH BASIN UPDATE 📣
The U.S. Army Corps of Engineer is adjusting operations at JE Roush, Salamonie, and Mississinewa Lakes due to the decrease in downstream stages. Downstream stages on the Wabash River crested on Sunday, following the heavy rainfall last week, and have continued to decline.
Effective 18 August 2026, USACE will begin increasing outflows from the reservoirs as stages have begun to fall to safe levels downstream. Releases have increased to approximately 1,500 cfs at JE Roush Lake with Salamonie and Mississinewa to follow as downstream conditions allow. 
The reservoir and dam are operating as designed. This is a planned and controlled operational adjustment based on current conditions.
Thomas Beeching: Why was JE Roush selected first? Didn't that watershed receive the least amount of rainfall?
Mississinewa Lake, U.S. Army Corps of Engineers, Chicago District: Thomas Beeching Roush typically takes priority due to their large watershed and smaller capacity. They fill up rather quickly and require the first release availability. Second priority typically falls to Mississinewa.
Shirley Hileman: What did the Wabash crest at in Peru?

Mississinewa Lake, U.S. Army Corps of Engineers, Chicago District commented on Shirley's comment
as all three lakes start to release, well bring it higher than the 11.83 feet that it hit last Thursday.

The dam is 8000' (2.4km) long with a hydraulic height of 122' (37m) and a structural height of 140' (43m). The emergency spillway is 1550' (472m) with a discharge capacity of 122.4kcfs. The normal storage is 75,200 acre-feet and the maximum storage is 368,400 acre-feet. [LakesOnline]
I could not find the capacity of the outlet works. My guess is around 5kcfs.

I think this is the emergency spillway. The water is then allowed to flow across farmer's fields until it reaches the Wabash River.

The USACE had another lesson about building a dam on a karst landscape without a foundation cutoff wall. They had to spend a lot of money later to add the cutoff wall.
keller
The dam had seepage issues. So, the USACE had to add a cutoff wall up to a depth of 235' (71.6m).
[Given the device in the photo, they are using a hydromill to build a diaphragm wall.]

Two pedestrian Bridges over White Lick Creek in Plainfield, IN, and crane operation

North: (Satellite
South: (Satellite, it is too new to be on the map when I published. It is south of the restroom)

Facebook Reel
Scott Tucker: That " crane operator" is rough as a cob.
Kelly Rhudy: Scott Tucker yea cuz that’s an easy job ….

Joe Wallin commented on the above reel, cropped

This YouTube short explains the history of the 1920 truss. He confirms it's a pin-connected truss.

I was surprised how much the bridge was swinging back and forth in the above reel. Scott's comment above indicates I was correct to be surprised. I spent several days watching an LTM 1450-8.1 crane lift steel beams over the building below to construct a commons area in the Downers Grove South courtyard. As you can see, the boom is short, but the luffer jib is long. That luffer configuration allows them to lift the beams over the building and reach the far side of the courtyard by lowering the luffer. Since they use a short radius when hooking up to a beam in the parking lot, the cable is long because of the length of the luffer. It struck me that I never saw the load swing back and forth, even after it was slewed over the building. I watch the lift of several steel beams over the course of several days and every time the hook was lowered over the beam with no pendulum action.
20200728 2489

Then one day I got there early so that I could watch them raise the luffer for the workday. It took about 5 minutes.
20200805 2610

Since they were ready with the crane before the riggers were ready to work, the oiler got some time in the cab for practice. He demonstrated that the hook does want to swing back and forth. And he was unable to stop the pendulum action. When the operator got back in the cab, the hook immediately quit swinging. So, I agree with Kelly that it is hard to learn how to avoid swinging the load. But I agree with Scott, why would an operator that has not learned how to stop the swing be allowed to do an important lift. 
These two screenshots show how much the hook was swinging. It is now clear which object on the parking lot the oiler was aiming for.

There was already a pedestrian bridge that connected the trails on both sides of the river. But the truss bridge allows them to easily get their lawnmower to the other side of the park.
