1922+1929 Burgess Falls Dam, Flumes and 360kw Power House on Falling Water River

Dam: (Satellite)
Upstream Flume Suspension Bridge: (see below for satellite)
Power House: (Satellite, it was somewhere downstream of the falls)

"The first dam was completed in 1922. The dam was 26 feet high and 310 feet long and had a concrete section and an earthfill section with a concrete core wall. The project used the dam to divert the flow of the Falling Water River through a flume to a power house located below Burgess Falls. It had a 500 horse power turbine with a 360 kilowatt generator." The 1922 dam and power house were destroyed by a flood on Jun 29, 1928. Replacements were completed in Sep 1929. [Cookeville]

"A new steel-reinforced-concrete dam and powerhouse were built in 1929, and the plant operated continually until 1951, and its contents were sold for salvage. In 1973, the City of Cookeville sold its interests in the property to the State of Tennessee which has developed the domain as a state natural area." [nps, p19]

Trail/Erie/D&H Quadrangle Lattice Bridge over Starrucca Creek

(Bridge Hunter; no Historic Bridges; B&T; Satellite)

"1904 lattice through truss over Starrucca Creek. A parallel plate girder bridge was added in 1929. It appears that the truss was abandoned prior to the abandonment of the line itself." [BridgeHunter]
It was renovated for use by the D&H Trail in 2019-20. [B&T]

The Starrucca Creek Bridge, a unique quadrangular lattice through truss, was erected over Starrucca Creek on the Delaware & Hudson Railroad in northeast Pennsylvania. The quadrangle lattice through truss was built in 1904, and a parallel plate girder bridge was added in 1929. The route between Carbondale and Lanesboro, including this bridge, was abandoned in 1982.
The unique crossing has since been renovated and incorporated into a scenic rail-to-trail.
A history of the Delaware & Hudson Railroad Penn Division can be found at my partner site, Abandoned, at https://abandonedonline.net/.../delaware-hudson-railway.../
Jarrett Spamiels: I thought the Penn division was Closed by Guilford in 86.

We can see from the exposed eastern abutment that the girder bridge has been removed.

This bridge is just a little over a 1000' upstream from the famous Erie Starrucca Viaduct. In fact, the viaduct went over the D&H.

1857-1963 B&O Tunnels #15, #16, #17 and #18 near Cairo, WV and #22

B&O either daylighted or bypassed these tunnels in 1963. The abandoned Parkersburg Branch of the B&O is now the 72-mile North Bend Rail-Trail.
#15: (Bridge Hunter, daylighted in place)
#16: (Bridge Hunter, daylighted in place)
#17: (Bridge Hunter, see below for satellite, still exists because the new route bypassed the tunnel)
#18: (Bridge Hunter, daylighted in place)
#22: (Bridge HunterSatellite, by passed)

One of several photos uploaded by Robert Elder to BridgeHunter-#17
"I spent about an hour in this tunnel this morning [Oct 30, 2014]. I will upload photos as soon as I can. Because this tunnel was bypassed in 1963, it retains a very high degree of historical integrity. One can clearly see that the stone is the original material and the brick was just use for patch work. Although it is not the longest tunnel on the trail, it is perhaps one of the most significant given it's relatively unaltered condition."

This map illustrates that when an engineer designs a railroad route along a river in the mountains, she or he has to make a difficult decision concerning the height of the route. A higher route has shorter tunnels but more expensive bridges. A lower route has cheaper bridges but longer tunnels.

The topo lines clearly shows where the cuts were made. The bypass for #17 is just south of the tunnel.

Neal Reynolds commented on Jane's post
from this website, a great read for rail buffs.
[But I could not find a link to the web site!]

"I have not yet been able to determine the locations of all of the lost tunnels on the Parkersburg Branch of the B&O Railroad. But, looking at the topography between Cornwallis and Cairo, and noting the tunnel numbering sequence, the locations in this area are obvious. I have also field checked the locations of Tunnels #14-#17. Tunnel #17 is extant, just abandoned. The other tunnels between #13 (Bonds Creek Tunnel) and #19 (Silver Run Tunnel) have been daylighted." [Robert Elder comment on BridgeHunter-#18] Tunnels #13 and #19 not only still exist, the trail goes through them.

"North Bend Rail Trail stretches 72 miles across north-central and western West Virginia. This wilderness path takes travelers across 36 bridges and through 10 tunnels and is part of the 5,500-mile American Discovery Trail, which spans the length of the United States. The trail has become one of the most renowned recreational trails through the Appalachians, and is known for its mountainous scenery and varied views of shaded tree canopies, rock cuts and farmland. Highlights include a 2,297-foot tunnel and the 'haunted' Silver Run Tunnel." [wvstateparks]

The name of the longest tunnel is Central Station Tunnel, but I have not been able to find its location. [traillink, specifies a length of 2,207'.]

I had to hunt for a while, but I did find an overview map of the trail.

Bonus: #22 (Rodimer)

1897-1938 Brown's Bridge over Monogahela River at Homestead, PA

(no Bridge Hunter; Satellite, at the end of the Old Browns Hill Road)

Stuff Thats Gone posted four images with the comment:
... the 1902 Fowler 'map' of Homestead PA shows the original 1897 Homestead & Highland Bridge aka Brown's Bridge... built for the streetcar line from Highland Park... it's eastern end landed at 2nd Avenue and was subject to congestion because of two 9-ft lanes... In 1937 the Homestead High Level Bridge now Homestead Grays Bridge was constructed which landed at 8th Avenue, flying over the multiple railroad lines... and was a wide four lanes... They dropped the "Low Level Bridge" span by Span in early 1938...
... The STG boys visited the remaining bridge abutments in the 1990s...

"Brown’s Bridge, also called the Homestead & Highland Bridge, opened in 1895. The 1,300-foot truss bridge with five spans cost $150,000 to build. It rose 54 feet above water level."

In addition to fishing, "eagle watching has become popular on Guntersville Lake, where over 20 mating pairs visit each year. One of the most easily viewed nests is on the north side of Guntersville Dam and can be observed from a small parking area at the intersection of Dam Reservation Road and Painted Bluff Road." There are several trails, one of which goes to "a cave that was used during the Civil War to mine saltpeter, a basic ingredient of gunpowder."

Guntersville Lock posted five photos with the comment:
Intermittent closures at Guntersville Lock have you scratchin your head, trying to figure out what’s going on? 
Lock and dam mechanics from Wilson Lock, Pickwick Lock, and Guntersville joined forces, and expertise to repair a bent valve stem in the Guntersville Lock main chamber. The functionality of the valve stem is crucial because it connects the valve machinery and the valve together to lift and lower the valve. Left in disrepair, Guntersville Lock and Dam would only have one filling valve. If it were to fail, Guntersville’s main lock would become completely inoperable bringing all commerce on the Tennessee River to a screeching halt. 
We want everything to...flow (like water) so, we’re working hard to get things up and running and resume normal operations soon!

Railroad Overpass in Kilmany VIC, Australia

(Satellite, they are building a new alignment for Princes Hwy south of the existing road.)

These photos caught my eye because the arch struck me as being very flat. And then I learned that this rather big bridge is just taking a railroad over a 4-lane highway.
Major Road Projects Victoria posted two photos with the comment:
Numbers in action 🔢
On the Princes Highway Upgrade between Traralgon and Sale, we’re installing an impressive-looking rail bridge for the Bairnsdale railway line in Kilmany. Here’s a snapshot:
- 16 arch segments  
- 450 tonnes of structural steel  
- 800 tonne mobile crane and 350 tonne crawler crane to handle the lifting 
- 1000 cubic metres of concrete poured once we’re finished
In layman’s terms, that’s a lot! It’s made out of z-grade steel, a low-sulfur steel with an ability to bend and warp, which is a good thing, meaning it can flex for heavy loads.
With new lanes now open between Sheepwash Creek and Flynn’s Creek Road and Velore and Templetons Road, we’re getting close to sliding in the bridge structure in the middle of the year.

[I wish the numbers included the length of the span.]



The arch looked flat because the photos are showing just the top part of it. The railroad overpass is so big because it is heavily skewed with the highway and they dug a deep valley for the road.
Eb Rabich commented on the above post

This view shows that they are building the new road alignment south of the existing road.
