I have yet to figure out how the gates work on the dams of the New York State Barge Canal.

Dennis DeBruler: Kathy Hanna Given that the dam is touching the lock, I think it is E15 at Fort Plain, https://maps.app.goo.gl/3ZpxHu6XWQVNNJyZA, instead of E14 at Canajoharie, https://maps.app.goo.gl/qaak6xmuuxyh2UgA6.

The bridge from which I took the top street view is a truss bridge. I tried researching it, but I could not find any information on it. 

Street View, Sep 2014

I did find a unique 1910 cantilever bridge that is further upstream for River Road.

Bridge E-28
"The bridge was originally configured as a traditional simple span through truss with concrete piers, but the plate girder cantilever alteration was added when the canal was widened in 1948, which resulted in the removal of one of the concrete piers for the through truss."

Lost Erie Canal Bridges

Postcard via Bridge Hunter

The 1914 New York State Barge Canal channelized the Mohawk River in this area. The original canal was a traditional canal above the riverbank.  The buildings in the above image were along the east side of Canal Street, and the canal was effectively an alley for those buildings. It appears that today's Legion Street was built on the canal's right-of-way.  The bridge in the image is probably Main Street or River Street. I guessed Main Street: (Satellite)

The new Main Street Bridge • Dayton Ohio • early 1900s!

In the early 1900s, the City of Dayton replaced the steel bridge spanning Main Street with one made of reinforced concrete. The new bridge was built because the steel bridge could not carry the weight of electric street cars according to “On This Date In Dayton’s History” by historian Curt Dalton. The bridge was constructed in seven spans and was one of the first concrete bridges built. At 54-feet [16m] wide and 588-feet [149m] in length, it was said to be the longest in the world for a period of time, according to Dalton’s research. [Lisa Powell via DaytonDailyNews]

And another colorization. Did the above artists add the car? That explains why it looks so skinny. They also added people.

I include an image with a streetcar since that is why this bridge was built.

The original (1835) bridge was a covered bridge. It looks like the river is flooded.

The 1871 bridge was an inverted-bowstring truss bridge.

An extract from THE BRIDGES OF DAYTON by Charles F. Sullivan

The Main street bridge was replaced by a steel structure, different from any other bridge I have ever seen. It was four spans, with a steel pillar upon each pier, and from the top of these was swung a steel bar down in a circular form and up to the top of the next pillar, so the arch of them was hanging instead of upright as usual. This allowed of much swinging of the bridge, without danger, but with the coming of the electric street cars, the people became afraid of it and the cars were required to pass each other at the piers, and the swinging was not as noticeable. Nothing ever happened there but eventually the bridge was condemned and about 1903 a temporary bridge was built below the bridge site and was used during the construction of the concrete bridge by H. E. Talbot & Co., the contractors. The old bridge was stored for a number of years and then two spans were erected at Summit street over Wolf creek, and a sign was placed at each end of the bridge, cautioning the public against heavy loads across it. One day two heavily loaded trucks going in opposite directions and at too high a speed, passed in the middle of a span, and that was too much and bridge and trucks all went into the creek bed, but no one received serious injury from it.

All of the elegant old buildings are gone.

"Ponte Infante Dom Henrique is a modern elevated road bridge in Porto, inaugurated in 2003. It pays homage to Prince Henry the Navigator and is known for its contemporary slim profile and stunning views across the Douro River. Designed by Adao da Fonseca and Francisco Millanes Mato, this iconic structure features a 280-meter concrete arch span, reaching a height of 72 meters."

behindagreatproject
"Achieving visual transparency implied placing the arch bases as high as practical up the riverbanks, which drove the 280 m main span and the relatively small arch rise of about 25 m. The resulting arch span-to-rise ratio of 11.2 exceeds the historic range of between 6 and 10. The arch itself has a constant thickness of 1.5 m, resulting in the record-setting slenderness of 186.7 – the conventional range falling between 40 and 90. Instead of curved profile, the arch follows a polygonal longitudinal profile with subtle kinks at each link pier, nearly approximating the antifunicular of the dead loads."
Most arch bridges have a stiff arch and a flexible deck. This bridge has a flexible arch and a stiff deck. That is, the big box-girder deck helps carry the loads. 

This photo provides a better view of the support and cables that provided the falsework during construction.

Removing the supports was a non-trivial operation in its own right.

Black Bridge was the historical, and still is the local's, name for the bridge. [Harold Pepperman comment on BridgeHunter] Some sources call it the Jersey Shore Bridge. I choose to go with the road that it carries because Jersey Shore is already in the title.

18. EAST ELEVATION - Pine Creek Bridge, River Road spanning Pine Creek, Jersey Shore, Lycoming County, PA

Significance: The Pine Creek Bridge is an outstanding example of a lenticular through truss. The lenticular, or parabolic, truss is a type developed during the mid-nineteenth century in Europe, but it enjoyed its greatest popularity in forms derived from designs by William O. Douglas and Charles Jarvis, engineers associated with the Berlin Iron Bridge Company. This company was the main producer ofthis unusual truss form, which was erected in many rural and urban settings throughout the United States between 1878 and 1900. The Pine Creek Bridge is one ofthe longest single span bridges (288' [88m]) remaining in a group of about fifty surviving lenticulars. Its Warren pattern web bracing was typical for such long lenticulars as were the highly decorated portals for such through truss bridges. The Pine Creek Bridge was placed on the National Register of Historic Places on June 22, 1988. [HAER_data]

It is obviously a pin-connected truss.

"This bridge was rehabilitated 2008-2011 extensively to continue to carry vehicular traffic at a high weight limit" [HistoricBridges]

I got an historic barrel shot to compare with the above shot of the rebuilt bridge because HistoricBridges complains about the changes that were made to the edge bracing.

PADOT found that the deterioration was much worse than they thought after they had disassembled the bridge. [Anonymous comment on BridgeHunter]

So, I'm just glad that they decided to rebuild a pin-connected Lenticular bridge complete with ornamentation.

1883+1896+1968 BNSF/Frisco Bridge over Verdigris River near Catoosa, OK

Bridges & Tunnels posted two photos with the comment:

Researching the history of certain bridges—especially railroad crossings—can be difficult due to limited records and inaccessible sources. The Verdigris River crossing of the Burlington Northern Santa Fe Railroad (BNSF) near Catoosa, Oklahoma, has an uncertain early history. The current bridge opened in December 1970 as part of the McClellan-Kerr Arkansas River Navigation System, but it's had at least two earlier iterations.

Of course, my research isn't complete by any means. I've contacted BNSF to see if there is information to be obtained, and I'm always interested in corrections/updates from others as well.

📸 More photos + history: https://bridgestunnels.com/.../verdigris-river-railroad.../

Daren Genau: I suggest you figure out who the original Railroad was and contact that historical Society. BNSF doesn’t know shit about their history.

Might be Frisco or Santa Fe

Bridges & Tunnels: Daren Genau Thanks! The local historic society was actually asking others about the bridge’s history so I’ll start with some railroading oriented groups.
