Although I know almost nothing about bridges, I did live in Clark Fork for decades. The original railroad bridge was built around 1891 - at least, the historical society has photos of the builder's camp during construction from that time. The original wagon bridge (now gone) was built in 1919. The local papers noted it featured "five steel spans, each 200 feet long, resting on six concrete piers." When the original railroad bridge was replaced in 1957, Northern Pacific paid the county to take over their old bridge, which became a one-way bridge designed for heavy loads - up to 250 tons. The original old wagon bridge was still being used by pedestrians 'til 1999. In 2002 the county secured funding to build a new vehicle bridge alongside the old railroad bridge. The railroad bridge was converted to a pedestrian bridge, and the original Wagon Bridge was torn down.

While looking for information on the Camas, Washington wagon bridge, Google served me up a listing for an HO scale brass model of this bridge, which features amazing detail of the Phoenix columns and portals.

Wow another beautiful memorable historical truss being needlessly destroyed. What a waste of tax payer dollars. As if they couldn't locate the new slab of cement a little way up the river and leave the beautiful historic truss up as at least a foot bridge. Wasting money and destroying our legacies of the past seems to be a hallmark of this dreadful present day!

350 cars a day? There is nothing but a couple houses on the other side. Talk about an inflated ADT count. This bridge actually appears to have been cared for and now they want to scrap it? They say Ignorance is Bliss...

This is probably one of the longest such pin connected truss bridges in the state/region, yet that is not saving it from demolition.

News Article:

From the county website:

It's been closed for 4 years. "Temporarily" closed for inspection in 2015, which everything they were worried about (Pins) passed inspection BUT the roadbed was (and clearly is) in such bad shape that they didn't reopen it.

There's apparently plans to reuse it as part of a cycling trail, which I hope comes to fruition.

This bridge is famous for a scene in "Breakheart Pass" (1975) staring Charles Bronson. The train stops in the middle of the bridge and the Fireman falls to his death (in the movie of course). Charles Bronson walks all the way to the bottom to pronounce the man dead.

If you like Ospreys you will find LOTS of them on bridges in the Pacific Northwest, Idaho, Oregon, Washington, etc. If the nest is in use, angry Ospreys will fly around squawking while you walk on the bridge. An unfortunate side effect of the nesting is the immense amount of "droppings" that drip down the side of the bridge. Aside from possible adverse effects to the steel and paint, this can be visually unpleasant. The Armitage Bridge in Oregon had its beautiful portal bracing covered in white streaks when I was there. I know there are man-made Osprey nest towers that can be built, I wish they would build some near the bridges so they can nest in peace nearby.

According to this Northern Pacific bridge book:

The truss was built here in 1916, indicating it was likely relocated. Could it be possible that this was originally a stationary span built elsewhere in the 1880s, and moved here?

Posted September 9, 2018, by Fmiser (fmiser [at] gmail [dot] com)

I saw a number of timber suspension pedestrian bridges. This seems to be a typical example.

Karl - Thanks for the history!

I saw this bridge through the trees as I was driving west on US12 - but time and my long trailer prevented me from stopping and exploring. My research since make me really regret that I didn't try harder to get to it.

I found a stock photo here:

That, plus my memory and Douglas's drawing provided the data for the sketch I added. The sketch is probably not dimensionally accurate, but it shows the unusually construction.

Posted September 9, 2018, by John Marvig (marvigj27 [at] gmail [dot] com)

According to Northern Pacific Track Charts, this bridge was built in 1927. Guessing by the trusses, this is likely a relocated structure.

Posted September 9, 2018, by Fmiser (fmiser [at] gmail [dot] com)

I spotted this soon enough as I was driving by I didn't even have to turn around! It is a fine old span in good repair. And as a bonus - there was an osprey nesting on the span. I didn't have a lot of time but I got a few photos of the bridge and of the nest. I added the nest to Osprey Watch.

Posted September 9, 2018, by Fmiser (fmiser [at] gmail [dot] com)

As I drove past I first though "That's a strange deck - and a rather light trestle - for a railroad." I dropped a waypoint and looked into it later and from satellite it's obvious it carries water!

I didn't have time to stop, and no time to get my camera out - so sorry that I don't have any photos.

But here is a streetview link.

Posted August 7, 2018, by Kyle Jarvis (kylejamesjarvis [at] mail [dot] com)

I doubt the 1939 build date for this bridge. There are no dates on the bridge, and 1939 would mean that this bridge was built after the Upper West Branch bridge on highway 57, which is a much more modern design. The style of this bridge, along with it's low 12"1' clearance and very light weight rating, combined with the 1925 date for the construction of the Dickensheet Bridge up stream, both of which are part of the old road from Priest River, ID to Coolin on Priest Lake, would lead me to think this bridge was built probably in the mid 1920's.

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

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.

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.

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 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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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!

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.
