Based on google imagery it looks like the bridge is in place, google street view show it sitting waiting to be put into place after a fresh red paint was added. Thoughts or any info appreciated.

My guess is they relocated it here long ago, and took out some center panels. It would be easy with a pin-connected truss.

Looks like a 4 slope Parker truss to me. Nice find!

I'm not sure of the design of this bridge or unable to locate a history.

Posted September 14, 2016, by Luke

John and I had the exact same thought a couple of days ago.

An article on the construction of the new bridge confirms that they were relocated:

The second Omaha bridge had four 250-foot, eleven-panel Whipple trusses, and two tracks. The first Plattsmouth bridge's two Whipple spans were moved to a Des Moines River bridge, UP moved Pegram trusses to Idaho, and C&NW moved spans from the first Blair bridge to Wyoming. Some chance that these two spans are from Omaha?

Sorry. Moved too fast.

You mean US-90. I-90 lies far, far, to the south.

Reminds me of the Mercer Pike Bridge incident in Pennsylvania. Although as a more complicated Pratt through truss intended to be reused on a highway, "piecing together" was not an option with that bridge.

Carefully written contracts, on-site monitoring by the owner, and most importantly skilled contractors are essential to preventing this.

Lastly, Kingpost truss bridges were not a standard bridge type in 1950, since steel stringer bridges were very economical for this span length. The bridge probably was either relocated in 1950, or pieced together from parts of another bridge in 1950.

Posted July 26, 2016, by Clark Vance (cvance [at] dogmail [dot] com)

So, write those contracts carefully!

Posted July 26, 2016, by J.P. (wildcatjon2000 [at] gmail [dot] com)

So I guess the company hired to move the truss, decided lets just cut it up. Glad the county didn't give up on it.

Bridge closed as of today for demolition. Will be replaced and reopened by the end of November.

The side platforms may have been for water barrels for fire fighting purposes. It was common on long trestles to have some water in case the steam locomotive dropped some hot cinders which started a fire.

Posted February 29, 2016, by Eddie (hillelectric [at] silverstar [dot] com)

I visited this bridge in 2004 before the rails to trails program restored the deck and installed safety railings. I walked across it with my son and it was in fairly good shape. It had two small side platforms that were mostly rotted away. They were just enough area to stand at one time. Not sure what they were built for? I have many pictures from that day if anyone is interested I will try and find them. This rail line was built during the push by the railroads to cash in on the many eager people wanting to explore Yellowstone and Teton Park and also to transport agricultural goods from Teton Valley Idaho and some of the communities along the way. The line reached as far as Victor Idaho and tourists could travel by bus from there over Teton Pass to Jackson Hole and from there on in to the parks. Sometime in the early 1980s they quit running trains to Victor and made the end of the line the little town of Tetonia which lies about 15 miles before Victor. Tetonia had several large grain elevators that serviced the area farmers. I remember seeing the train pull in to Victor as a child. It still had one car available as a coach car and you could catch a train from Ashton to Victor. I also drove grain trucks from my family's farm in Teton Valley to Tetonia and watched the grain being loaded on the train, even helping the elevator operator move the train cars into position. Sometime in the early 90s they quit running trains on the branch completely and within a few years pulled tracks and ties leaving only the bed and two magnificent trestles, this one and another one South of here on Bitch Creek Canyon. Both are beautiful industrial works of art with massive steel beams and wood timbers. The railroads talked of removing them for liability reasons before the pathway organization saved them.

Posted June 30, 2015, by Robert Elder (robertelder1 [at] gmail [dot] com)

Okay, the new location makes much more sense.

Posted June 30, 2015, by Ian Martin

Yeah- I fixed the coordinates and added dates based off the postcard that was linked; should've thought to remove the Streetview as well.

Posted June 29, 2015, by Luke

I've found that the streetview (Which I've deleted since a bridge replaced in the 30s wouldn't have one.) is pointing at a trail bridge.

Posted June 29, 2015, by Nathan Holth (webmaster [at] historicbridges [dot] org)

I have no idea what the Streetview is pointing at... this listing appears to be for a previous bridge over the large, deep, Lake Pend Oreille (note my correct spelling) which even today retains a full size swing bridge on the adjacent RR bridge.

Posted June 29, 2015, by Robert Elder

Is this the right bridge? This little stream seems rather small for a lift bridge.

Posted February 18, 2015, by Nathan Holth (webmaster [at] historicbridges [dot] org)

Surprised nobody has commented about this bridge. The bridge shows evidence of widespread alteration, since there are a massive number of empty river holes on the portal and sway bracing. My first guess would be that the bridge was narrowed... which also makes one wonder if the bridge was relocated and reused at this location. It would be interesting to know. Finally, taking into consideration the alterations, what I can see of the bridge leads me to believe that this bridge may be the work of famous engineer George Morison. The large lattice portal and sway bracing, Whipple truss configuration, and the arrangement and composition of some of the truss members are what suggests this possibility.

Here is a picture of the bridge when new:

Posted June 5, 2014, by Karl Strauss (straus8 [at] ca [dot] rr [dot] com)

This is a swing bridge over a non-navigable river. When the Clearwater River Railroad wars were taking place, the Northern Pacific and Oregon-Washington Railroad and Navigation (OWR&N) were racing towards the Kamiah region with its bountiful forests and just as bountiful fields of grain. The first one there would grab the honeypot. The NP was winning the war but the OWN&R had an upper hand. They convinced a judge that the Clearwater river (average depths of some 6 feet) was navigable and also that it was of such quality that a steamboat could navigate it, and therefore a bridge - an expensive movable bridge was necessary per US law.

In the spring thaw the river does indeed become a raging torrent and the OWN&R folks knew this. On a spring day they convinced the captain of a sternwheeler based in nearby Lewiston, rumored to be a notorious drunk, to make the run to Kamiah on dare. And he took up the challenge. With Judge and Jury on hand the steamboat made its one and only entry into Kamiah and the judge ordered that a movable bridge be built.

The motor mechanism is long removed and the rails welded close but the large bull gear remains.

This bridge was lost in 1989. The plaque that is shown in one of the photos was recovered and was archived at the Owyhee County Museum in Murphy.

Posted December 9, 2012, by James McCray (jamesinslocomb [at] yahoo [dot] com)

One of the more interesting bridges I found. I wonder what happened to the bridge's center span.....unless the current center span is original to the bridge?

Posted December 8, 2012, by Don Morrison

Apparently, it's a bridge that carries the 26,000 foot penstock of the Grace power plant complex. So, yeah - it's an aquaduct.

Posted December 8, 2012, by Clark Vance (cvance [at] dogmail [dot] com)

It is a flume for a power plant located several miles south and west of the location. I think it's in the process of being decommissioned and the dam(s) removed to restore the river.

Posted December 8, 2012, by Mike Szyhowski (se02mike [at] att [dot] net)

This does not appear to be a railroad bridge. I believe it is an aqueduct.

Posted December 3, 2012, by Mike Goff (michael [dot] goff [at] hotmail [dot] com)

The old Goff Bridge was a steel through truss while the new bridge is tied arch. Itís not exactly a model for the new bridge, but the new arch bridge is defiantly a nicer structure than a pre-stressed girder bridge.

I was able to find a photo on ITD's Flickr site of the old bridge during the construction of the new.

Posted December 2, 2012, by Tom Batcheller (lhb91 [at] msn [dot] com)

I may be wrong, but the narrow bridge that was at this crossing was used as a "model" for this present-day Goff Bridge. Do we have any pictures of the 'old' bridge that stood at this crossing?

My dads family lived on this island when there was just a boat and a railroad bridge. We wondered for years where this island was and what had happened with it. Unfortunately he sold the island when his mother died. They were a blended family of Smith's and Profits living there at that time. There should be a hold house with a well that was dug by my Grandmothers nephew so that they did not have to carry water to the house.

This is a part of our family history. And yes, we still talk about the island. I am glad to finally have the knowledge of where it is. Mystery solved.

Posted March 21, 2012, by Craig Philpott (cphilpott [at] puc [dot] edu)

Quite likely the 1992 date is the year this bridge was replaced...

Looks like I need to correct my previous comment about these triple-intersectionals being more common than quadruple intersectionals. I assumed they were more common based on the fact that they are dominant in Kansas. They appear to be extremely rare elsewhere, however.

Posted November 23, 2011, by Nathan (thaddeusthudpucker [at] gmail [dot] com)

As long as I can remember, the railroad bridge was the main bridge across the river. The Stevens Bridge was unsafe according to my grandparents who lived near the Idaho/Montana border at the time. I do not definitively know when the Stevens Bridge was torn down, but I do know that the "detour" was there in the early 90's

I consider myself a "Details Junkie" and have compiled way too much stuff in my noggin through the years. Since plaques are more than often missing and county records buried under dust, I look for these little markers to help identify a builder.

From about 1885 to the early 1890's King used a style of portal bracing that I have dubbed the "X's and O's" style. Indiana has a couple of these and the Bridge Island span has very similar bracing. Certainly other builders have used circles in their bracing, but the largest one in this span seems to be a perfect match to the Indiana ones.

Some might not consider this a "slam dunk", but I feel pretty confident in calling this one a King.

*The big circle on the Indiana spans also have that flange but it is turned the other way.

Posted September 12, 2011, by Gene McCluney (mccluney [at] sbcglobal [dot] net)

Regarding Bridge maker ID. There are a few ways to determine "maker" of bridges. One, and the most telling is a Nameplate on the bridge. The King Iron Bridge Company was fairly good about putting a good solid nameplate on their bridges, usually on a vertical. While it is not shown in the photos attached to this listing, that doesn't mean it doesn't exist. Another would be county records, which are available at the county seat of the county where the bridge is located. Then there is the NBI, an older edition, when this was an open county road. I realize I haven't answered your specific question about this specific bridge, but I think the info is not that hard to find.

Posted September 12, 2011, by Michael Goff (michael [dot] goff [at] odot [dot] state [dot] or [dot] us)


I am not and never claimed to be a truss bridge expert, there are just too few in my part of the country. I have got to know, what is the unique feature that links this bridge to the King Bridge Company?

I appreciate the information on this bridge. It is rather difficult to determine just about anything on these private structures.


Posted September 7, 2011, by Craig Philpott (cphilpott [at] puc [dot] edu)

How disappointing to hear this one is gone. I do hope the rest of your tour was more successful.

I made a big swing through Eastern Oregon last weekend and dipped into Idaho and SE Washington a little in my bridge hunting travels.

I drove through this location hoping to get a couple of photos of my own but arrived just in time to see the finished deck pour on the new bridge. The old truss has been replaced and there is now no sign now that it ever existed.

On a side note, the southbound bridge at this location has one of the worst riding decks I have ever driven. Large potholes, exposed rebar and tons of cold patching. I hope IDT is planning on reparing this structure as well.

Posted September 6, 2011, by Ben Tate

Was this bridge replaced(gone) or just bypassed?

Posted April 8, 2011, by Anthony Dillon (spansaver [at] hotmail [dot] com)

A nice looking and rather long bedstead truss.

The truss legs may have been removed during the renovation, or they might have been amputated in a past remodel. Often the legs have been encased in concrete to shore up the foundation. Unfortunately most people don't understand that the legs are actually part of the truss itself.

Posted April 8, 2011, by Nathan Holth (form3 [at] historicbridges [dot] org)

Fantastic find! Looks like it was originally a bedstead, although it appears its legs were cut so it now functions as a pony truss with vertical end posts.

Posted April 8, 2011, by Cheryl (idastuff [at] clearwire [dot] net)

Bridge was moved to the Gem Island Sports Complex in Emmett Idaho (Gem County). It is being used as a pedestrian Bridge at this time. Looking good.

Posted February 1, 2011, by Nathan Holth (form3 [at] historicbridges [dot] org)

They did a really gross pier replacement. The rollers from the swing are now hanging over nothing. The bridge looks great on the deck, but it looks a bit stupid in elevation view.

Posted February 1, 2011, by Matthew Lohry


I have a new theory. The lost Parker truss bridge was located several hundred feet to the west of this bridge, and was removed sometime between 1999 and 2004. The 1999 Google Earth ariel view shows the bridge crossing the river at Stevens Street, which was apparently ID 200 at the time. After the bridge was removed, the road was temporarily routed across this old railroad bridge, which was probably abandoned and rerouted across the current rail bridge, which can be seen in this street view (to the east). The road was routed across this bridge until the new UCEB was completed. I adjusted the GPS coordinates of the Parker truss on its page to reflect its actual location.

Posted February 1, 2011, by Anthony Dillon (spansaver [at] hotmail [dot] com)

It appears that this span and the Smoky Hill River Bridge in Kansas share very similar portal features and possibly even the same builder.

Interesting discussion on the differing Triple and Quadruple Lattice trusses. My knowledge of them here in Indiana is somewhat limited. We do have an abandoned dual-track Quadruple in Pulaski County:

But I am much more familiar with the Fredricksburg Bridge:

This may be the only surviving example of a non-railway built Triple-intersection Lattice. After being closed for many years on a county road, this bridge is scheduled to be moved to a park for trail use. It's survival and restoration will be a nice complement to the only Triple-intersection Pratt known to survive:

Posted February 1, 2011, by Matthew Lohry

Thanks for the clarification, Robert. As it turns out, I have seen the bridges that your links reference, but I've not noticed that they were triple-intersection Warrens--I think that I just saw the lattice configuration and assumed quadrangular, since those are most common in Minnesota and Wisconsin. Somehow, this bridge really stands out (maybe the silver paint!), and perhaps that's how I noticed it.

Posted February 1, 2011, by Robert Elder (robertelder1 [at] gmail [dot] com)


Interesting comment. The Quadrangular Lattice trusses seem to be dominant in the upper Midwest, but the Triple-Intersection Lattice trusses are the most common form of Lattice truss in other areas.

In Kansas, where the triple-intersectional trusses dominate, most of them appear to have been used by the Union Pacific Railroad, which also appears to have used this Idaho example.

The main variation I see with Triple-Intersectional Lattice trusses in Kansas is the portal bracing. Arched lattice bracing with Town Lacing is found on at least two Lattice truss bridges:

Other Triple-Intersectional Lattice trusses feature a less decorative bracing with V-lacing:

Ah this bridge. I always seemed to be passing through with daylight fading or the dead of night on the way to Missoula. Would have liked to stop and photograph one of those days.

Posted January 31, 2011, by Matthew Lohry

Wow! This bridge is incredible! I have seen plenty of double-intersection and quadrangular (quadruple intersection) Warren trusses, but this is the first triple-intersection Warren that I have ever seen! It is great to see that this beautiful structure was preserved and converted for trail use for the general public to enjoy!

Posted January 31, 2011, by Matthew Lohry

Looking at the construction of the current bridge is certainly indicative of the fact that this was indeed a railroad bridge at one time. The main trusses are very tall, very narrow, and extremely heavily built, which would be perfectly suitable for train traffic. Also, the approaches are heavy deck plate girder spans, which are used almost exclusively for railroads. If I were a betting man, I would place my money on this being the old RR, and the old road bridge being lost to the ugly UCEB.

Posted January 31, 2011, by K. A. Erickson

I had at one time this bridge posted with pictures as Clark River Railroad Bridge. Local history is a bit sketchy but the gist is that the current pedestrian bridge was a railroad bridge that they turned into a temporary road bridge while they built the new UCEB. There are tentative plans to connect a cross state Idaho trail using as a part.

Posted January 31, 2011, by James McCray (jamesinslocomb [at] yahoo [dot] com)

This is a bit confusing. The website ( has the old bridge as torn down, but it is shown as a Parker Truss. However this bridge (which is obviously the old Johnson Road bridge that is now turned into a pedestrian bridge) still exists next to the new Johnson road bridge, but it is a Pratt truss as seen on the street view and Google Earth. Can someone explain this? There must have been two parallel truss bridges or something.

Posted May 30, 2010, by Cliff Darby (clif30 [at] hotmail [dot] com)

IDK if I would say perfectly intact... viewing historical imagery on Google Earth it appears this structure has shifted in the last few years. Look at the approach in images from 04 and fast forward to 09... the bridge now has an interesting kink in it. Appears to have been moved, possibly by high water or the ravages of time.

Posted May 30, 2010, by D. W. Adams (weetbixmarmite [at] yahoo [dot] com)

Judging by Google's satellite and street views, this rail line seems to be long-since abandoned, but a magnificent bridge appears perfectly intact at this location. I can only assume it is this one, though I can't distinctly make out its truss details in the shadows. Bing has no bird's eye view of this area (yet).

It has to be a vehicular/road bridge, as it has an inspection date and vehicle per-day count in the statistics. Railroad bridges are not inspected by county and state road inspectors.

Is this a train bridge that goes over the Black Prince Creek as it goes into the St.Joe river? Or is this a people and auto bridge? I am trying to find an aerial view photo of the old train bridge over the Black Prince Creek as it flows into the river. Not far from there is a very very old abandoned saw mill high up overlooking the river. Does anyone know the original name of this sawmill?

Here is a picture I took of this bridge in December 2000 and some interesting information I found on Wikipedia. The picture of the jumper came from the wikipedia article.

Wikipedia article:

The I. B. Perrine Bridge at Twin Falls, Idaho is a four-lane span carrying U.S. Highway 93 over the Snake River Canyon. The bridge serves as the Twin Falls area's main link to Jerome County and Interstate 84.

Originally named the Twin Falls-Jerome Intercounty Bridge, Perrine Bridge is approximately 1,500 feet (457 m) long and 486 feet (148 m) above the Snake River. The original bridge was opened to traffic in September 1927 and at the time was the highest bridge in the world. The bridge was originally a toll bridge, but the tolls proved unpopular and were eliminated in 1940.

By the early 1970s the original bridge was outdated and unable to handle heavy loads and required replacement. Construction on the current bridge was completed in 1974.

Perrine Bridge is the only man-made structure in the United States where BASE jumping is allowed year-round without a permit. As such it is a popular destination for BASE jumping enthusiasts, who often refer to it as Potato Bridge.

Adjacent to the south end of the bridge is a parking area with a visitors' center, which allows for easy access to the bridge. To the east, along the south rim of the canyon, lies the dirt ramp used by Evel Knievel when he unsuccessfully attempted to jump the canyon on his motorcycle in 1974.

The bridge is named for I. B. Perrine, who spearheaded the early 20th Century irrigation projects in Idaho's Magic Valley region. Perrine is largely credited as the main founder of Twin Falls.

Official name I.B. Perrine Bridge

Carries 4 lanes of US-93

Crosses Snake River
