Metrotrails posted and HistoricBridges
Historic early 1900s postcard image the old Washington Street bridge in Boonton, New Jersey, a rare example of a pin-connected Pratt deck truss bridge built in 1895 by the Canton Bridge Company of Ohio. 
The northern span of the bridge was replaced in 1988 with two stringer spans.
This bridge was closed to all but pedestrian traffic in 2005 when the new route 202 Washington Street Bridge opened to traffic.
Steven Monarque: We used to jump off that bridge all the time back in High School.

"This is a rare example of a highway pin-connected truss that is mostly a deck truss, but with trusses that are outside of the deck edges rather than under the deck, and are partially positioned above the roadway elevation, although most of the trusses  remain below the elevation of the roadway. Sway bracing is positioned as a deck truss. The trusses are deep, and have an unusual horizontal member running through the middle of the trusses likely for additional stability."

Compare this photo to the one above where the boys are jumping off the bridge. It shows some of the revisions that were done to strengthen the bridge. In the foreground, a rolled beam has been added to the truss. And in the lower-right corner, bolts have been added. The rivets confuse me. They are too new for 1895 and too old for 1980. There must have been additional rehabilitations. (I found below a 1904 rehabilittion.)

I found that it was also rehabilitated in 1904. This may have been when the rivets were added.

We can see at least part of the masonry dam.

The spillway is built on an angle, probably to reduce its slope and the velocity of the water to reduce erosion.

Abandoned Bridge, Guard Gate #3 and Rocky Rift Diversion Dam for Erie Canal near Mindenville, NY

Erie Canal Overview

Ulf Jonsson posted eight photos with the comment: "By far the strangest bridge on the canals.  Between E-16 and E-17.   I posted about it before but i got some more pictures today.  I need to try to find time to stop here when driving up to Syracuse at some point."
Mike Karsten: The cantilevered back span supports the one side of the truss. It appears that the canal was widened and they built a new pier further back with the cantilevered span and re-used the old truss.
Paul Taylor: Key Details About the Bridge
• Location: Spans the canal and former rail alignments near Mindenville/St. Johnsville in Montgomery County.
• Design & Modification: Local historians and engineers note it is a distinctive metal truss structure featuring a cantilevered back span. Commenters and local archives suggest the bridge was altered and re-anchored on a new pier further back when the canal was widened into the modern Barge Canal system, reusing the older metal truss framework.
• Context: It previously connected local roadway paths across the waterway and the old West Shore Railroad tracks (now part of the Empire State Trail corridor).
• Current Status: The crossing has been closed to vehicle and public traffic for several years.

This diagram would be before the canal was enlarged.

Ted Olsen posted this.. apparently there were tracks where the road is now on the south side. That explain some of it. The ramp over the tracks must have been steel too.
Tim Rice: Ulf Jonsson yes, with heavy wooden planks for road deck.

To me old bridges just hold so much energy. 
The memories of the past. 
A different way of life, and the paths of many. 
-Like this one that once fully spanned the Canal from Minden to the St Johnsville area. 
This spot, used for a launch by the Amish sometimes is also on a spot where unfortunately, 
 people like to dump garbage. 
I walk it sometimes with a rifle, and shoot target in the woods near there. 
Every time I go in, I carry a bag for other people's refuse. 
If we abuse public land we lose the right to access. 
So even if we just pick up a little every time, 
maybe someday, we can still bring our grandkids to these beautiful little spots.
Michael Riley: When you see the two piers on these bridges, you know they are original. Many of them were infilled into one monolith abutment to add strength. These old bridges are so neat to see and if they haven't been subject to salt, they are in quite nice shape. It would be nice to save a few of these as pedestrian bridges. Here are a few posts I wrote about the bridges of Cayuga County. https://canalsplash.blogspot.com/search/label/bridge

Ted Olsen commented on Jeff's post
The next Schillner map to the west from the one depicting the bridge. The waterway from the top of the page is East Canada Creek. The smaller, narrow, linear water channel sandwiched, is the Enlarged era Mindenville feeder. It, along with the Enlarged Canal, got overdug and became the current Barge Canal waterway.

Ted Olsen commented on Jeff's post

I can't figure out exactly how the gates work. The above photo shows them down for a low flow and the photos below show them up for a high flow.

Cori Wilson posted three images with the comment: "The Rocky Rift Moveable Dam, part of the New York State Erie-Barge Canal, is located at the end of Depot Road, Manheim Center, Herkimer County, New York (coordinates. It was built in 1927 to replace an earlier fixed crest dam, using a movable three-span truss bridge design to maintain Mohawk River water levels for navigation. The dam was rehabilitated in 1982 to ensure continued functionality.
A significant event associated with the dam occurred on April 11, 1944, when Reuben Klock, a 64-year-old retired farmer and the dam's caretaker, drowned while attempting to lower the dam gates. Reports suggest he may have fallen into the canal while trying to loosen stuck gates with a hammer, standing on a narrow walkway. His body was recovered on May 6, 1944, one and a half miles east of Lock 16. Eighty one years ago today..."

Evidently, the Barge Canal was closed in May 2025 between locks E16 and E17 to make emergency repairs on the embankment for this dam. [canals]

The "!" is the dam, the weird dot is the guard gate and the bridge is near the lower-right corner.

Aerial view of Pymatuning Lake and the Causeway between Espyville, PA and Andover, OH, as seen from the Pennsylvania side.  The 2 1/2 mile Causeway is one of the most popular fishing areas of the lake.

The comment about it being a fishing area confused me until I saw the fishing area.

You need an aerial view to see the whole thing. This shows that the crossing is mostly dirt (an embankment). I'm guessing that the bridge part uses concrete girders.

The causeway crosses the Pymatuning Lake created by the Pymatuning Dam. The emergency spillway is on the right descending bank.

1885+1909 Capital Crescent Trail/Arizona Avenue/B&O Bridge over C&O Canal and Canal Road in Washington, DC

(Bridge Hunter; Historic Bridges; Satellite)


I don't think Arizona Avenue 

The span on the right goes over the C&O Canal.
Street View, Mar 2025

Bob Dover posted
The Arizona Avenue Trestle in Washington, DC, crosses the C&O Canal and Canal Road a few miles north of Georgetown. Completion of the Georgetown Branch Railroad required a new bridge to carry the rail line across the C&O Canal, as well as Canal Road adjacent to the canal. This was accomplished by disassembling two existing railroad bridges in other locations, transporting them to the C&O Canal, and re-assembling them in their current location at the intersection of Arizona Avenue and Canal Road, a few miles northwest of Georgetown. The bridge consists of two very different spans, both salvaged from earlier railroad lines in Pennsylvania in 1909. One span is shorter and skewed, while the other is much taller, suggesting that the two spans came from different rail lines.
In the late 1980s, the rail traffic was stopped. By 1990, the entire seven-mile rail line had been converted to recreational use as the Capital Crescent Trail. Today, the bridge carries bikes and joggers across the canal and Canal Road.

This shows how different the two spans are.
Alex PennCove Tucker, Dec 2022

It appears industry survived east of here longer than I would have guessed. (Rail service made it all the way to the late 1980s.) 
1977 photo by William Duvall from the collection of Benjamin Sullivan via BridgeHunter

One of the most significant bridges in the District, this rare railroad Whipple truss and skewed Pratt truss has been preserved for pedestrian use. It is however overgrown and extremely difficult to photograph in whole from the side. The bridge also has a small deck plate girder approach span in addition to the two trusses. For unknown reasons, a plate girders run alongside the deck inside the Pratt truss.
The bridge was reportedly originally built for the Baltimore and Ohio Railroad at Ridley Creek, Ridley Park, Pennsylvania southwest of Philadelphia and was moved by B&O to this location in 1909, and converted to trail use in 1992. The Whipple truss configuration and Carngie brands with the simple font both suggest the bridge dates to the 1880s, as such the reported 1885 construction date given on Bridgehunter.com would appear to be accurate.
[HistoricBridges]
The Capital Crescent Trail crosses the C&O Canal Towpath just south of the bridge. It is interesting that the C&O Towpath is also labeled "U.S. Bicycle Rte 50." The trail joins the Great Allegheny Passage (GAP Trail) in Cumberland, MD, and ot goes all the way to Pittsburgh.

1888-1943 Lost Upper Free Bridge over Illinois River at Peoria,IL

(Archived Bridge Hunter; Bridge Hunter; Satellite)

"Artistic license" makes this image look like it was AI generated. A swing span would never be partially closed while a boat is still going through the opening. And there is no pier for the swing span.
Unknown Artist via BridgeHunterkkk
"1888 – The wood-floored Upper Free Bridge at the narrows. On February 27, 1943, the bridge was struck by the towboat, “Sylvia T.” It was repaired; but right before its reopening on May 17, 1944, the “Sylvia T.” struck the bridge again and put it out of business for good. The United States War Department ordered the removal of debris from the channel, but the city disclaimed ownership and the War Department ultimately removed the debris and the center pier in 1947. The pier on the west side remains in place today. From the 1985 book Peoria! by Jerry Klein"

Tony Brocksmith posted two images with the comment:
The pictured bridge is just north of the McClugage (150) Bridge. One of the footings for this bridge, or a version of that bridge, is still visible on the Peoria side of the river, just east of the Water Works building.

Michele Sumner: In 1887 the first Santa Claus Parade was started as the kick off for the grand opening of that bridge and is the longest running Santa Claus Parade in the United States.
Bruce Phelps: That was the upper free bridge. I fished off the pilon while in high school. I am 88. My dad used to ice skate while going to kingman high school in 1930 when the river froze solid under that old bridge.

My great-grandfather (which is why I have the clipping).
He operated the Upper Free Bridge in his later years; his son, who at the time was State Senator Thomas Madden, got him the job (according to family lore).
