West Bridge (Washington)
Posted August 30, 2019, by Todd Clark

The bridge was more likely located at these coordinates:

46° 58.431'N; 123° 48.221'W

The current crossing area was the former crossing for the railroad.

Robert is correct. There are several small scale Marsh arches in Iowa with no bracing.

Posted August 29, 2019, by Robert Elder (robertelder1 [at] gmail [dot] com)

Some Marsh Arch Bridges have a brace between the arches and some do not. It generally depends on the span length.

There are a few factors that distinguish a Marsh Arch from a regular rainbow arch. Perhaps the main difference is the fact that Marsh Arch Bridges use a special type of reinforcing. There is actually a bonafide steel arch structure under that concrete instead of just rebar.

Posted August 29, 2019, by Ed Hollowell (erhollowell [at] aol [dot] com)

I could be wrong but doesn't a Marsh Arch have a element across the top between the arch tops.

Posted August 29, 2019, by Clark Vance (cvance [at] dogmail [dot] com)

Since Marsh isn't listed as the engineer a/o builder it may not carry the name. I consider any of the concrete arches of this type to go by the name Marsh just as we use Pratt even if not built by them. If there is a consistent classification we use on this site I'll always try to follow the convention.

Posted August 29, 2019, by Robert Elder (robertelder1 [at] gmail [dot] com)

Just my $0.02 - but this appears to be a Rainbow Arch, but not a Marsh Arch.

Posted August 29, 2019, by Clark Vance (cvance [at] dogmail [dot] com)

There is no category for Marsh pony arch so choosing Marsh Arch automatically determines "through" but Marsh can be added manually.

Posted August 29, 2019, by Daniel

Shouldn't this be listed as a pony arch rather than a through arch?

As of today this bridge is officially replaced. Drove by on highway 14 and the new bridge is in place, the original is floated away a few hundred feet.

The missing mid span was actually replaced in 1998-99. The middle 2 spans and support structure were taken out by a mudslide in 1988.

WA-20 Bridge (Washington)
Posted July 10, 2019, by John Marvig

This bridge looks like it has twinned (or four total) girders. This typically indicates an older girder bridge was strengthened and reused.

Working aboard a tugboat I have taken many barges and ships through the 150' wide water opening of this bridge. It's still a puzzle to me of how this bridge works!?!? I like the Northern Pacific sign that is still remains on the bridge.

Posted July 7, 2019, by Robert Banel (bob [dot] banel [at] aol [dot] com)

The Northern Pacific Railroad sign on this bridge always intrigued me as kid way back in the 1960's. With it's Ying-Yang symbol and the "Yellowstone Route" sub-title fired up our imagination. We made plans to walk to Yellowstone Park following the train tracks. It was later painted over when Burlington Northern Railroad was formed out of Northern Pacific, Great Northern, and Burlington and other railroads in 1970's. Somebody out there has restored the sign. Thank you to that "Somebody".

Posted July 7, 2019, by Robert Banel (bob [dot] banel [at] aol [dot] com)

I have always wonder about this bridge's eastern concrete support when viewed from beneath the bridge from the bank of the Cedar River. It has a tilt to it that was was compensated by a wedge shaped concrete pour where the metal truss rests on. Does anyone know the history of this or have a theory that might explain this. Perhaps a flood was responsible for the tilting. I'll will try later to take and post a photo of this strangely engineered repair. Thank you.

Posted July 5, 2019, by Luke

Also, if you find any information on where these steel truss bridges came from, seeing as they're all of earlier construction types, please comment so we can update the entries!

Posted July 5, 2019, by Luke

The date for this bridge and the still-extant Stetattle Creek Bridge came from Google's "Books" page results for Engineering News-Record, Volume 127:

Appears to be available at both the Seattle Public Library and the UW Library.

Thanks for this awesome resource! I work for the Cultural Resources Branch of North Cascades NP. I'm currently researching the Skagit River Railroad, and was wondering on what source material this information was based. I was pleased to see that this record was updated just last year, so maybe it's relatively fresh in your mind.

Thanks very much.

All the best,

The White River Bridge (SR-410) received a full paint job in 2018. Plans are in works to install a pedestrian bridge (Foothills Trail) in 2021 just up river at a former road bridge site next to the old NP/BN Buckley Viaduct. Footings for both the Buckley Viaduct and the former road bridge are still intact. The plan is to use the road bridge footings to support the trail bridge, which is planned to be able to carry EMS/Police vehicles should the current White River Bridge be closed for emergency reasons.

Mike, Of the photos you posted, No. 8-19 don't look like the same bridge and I believe they are of the downstream Union Pacific bridge. The rectangular covers at the top of the towers are the main giveaway.

It's "Ahtanum" Creek (note the final "m", not "n." Back in the 80s we lived in the area briefly. It's locally pronounced "uh-TAN-um", btw.

Sorry, I didn't zoom out on your map, as I've been familiar with this bridge for years and recognized it instantly when I saw the photo. Now I see that the map location above is 20 miles off, and to my knowledge there was never any similar bridge at the location indicated above.

Go to the coordinates above and check the street view from the bridge that replaced this one and you'll see it's the same bridge.

Posted May 20, 2019, by Rob Petersen (heyrob [at] usa [dot] net)

This bridge is listed a "Lost" but that is an error, the bridge is located a little north of the spot marked on your map, check the actual location at 47°11'28.1"N 121°01'00.1"W.

This bridge was likely constructed during the late 1910's or early 1920's based off the construction of similar bridges throughout Adams County. The 1900 construction date is likely a place holder in the NBI data due to the actual construction date being unknown.

Greg, your image is also related to the UP bridge, not of this one.

This bridge was taken down in 1983.

Posted March 4, 2019, by Mark Bozanich (markthemapper [at] gmail [dot] com)

According to the Anacortes Museum and Maritime Heritage Center, this bridge opened to traffic in 1915. The bridge connected Morris Street in LaConner with Snee Oosh Road on the west side of the Swinomish Channel. In fact, the museum refers to this as the Morris Street Bridge.

The Rainbow Bridge, about a half mile south, replaced the Morris Street Bridge in 1957.

I was Looking in one of my books and saw a picture of this bridge. In it the picture was taken before the dam was completed. and apparently the section removed according to the Photo was a arch span making this bridge a arch bridge. But now that the arch span is removed how would I list it?

The Cascade Wagon Road was the first state road designated by the Washington legislature in 1893. This bridge was built in 1930 as part of the Cascade Wagon Road, numbered Primary State Highway 17 in 1937. The highway was intended to cross Cascade Pass and Twisp Pass with a spur heading south to the unincorporated community of Stehekin. Part of this proposed route was never built. In the later 1940s, a route via Washington and Rainy Passes was surveyed that eventually became State Route 20, the North Cascades Highway. The final link was opened to traffic in September 1972.

The enclosed WSDOT photograph was taken in the early 1940s. Note the Washington State Highway 17 sign at the beginning of the bridge. The bracing above the roadway has since been modified so that the vertical clearance is the same the whole width of the roadway.

Posted February 13, 2019, by Mark Bozanich (markthemapper [at] gmail [dot] com)

I believe that this bridge was built in 1927, not 1937. The county highway from Mount Vernon to Anacortes was added to the state highway system as the Anacortes Branch of Primary State Highway 1 in 1937. The enclosed WSDOT photo shows this bridge circa 1938.

Posted February 11, 2019, by Rob Petersen (heyrob [at] usa [dot] net)

Well this bridge has been replaced by a modern concrete 2 track "trestle" with a new through plate girder span. The cool part is that they replaced the Milwaukee Road Logo sign also.

I will try to remember to get current photos to post here. It was built to double track the line to the Milwaukee Road Freight House, that is the Tacoma station for Sound Transit trains to Seattle, and is soon to be the new Tacoma Amtrak Station. It was used only once just over a year ago for the ill fated inaugural run on the Point Defiance Bypass, a new passenger rail route south of Tacoma, which still has not reopened for Amtrak trains, though local freight trains still work the line.

Posted January 29, 2019, by Arthur Allen (arthurallen [at] centurylink [dot] net)

I strongly believe this is the trestle shown at the beginning of It Happened At the World's Fair (1963) in the sequence showing Elvis Presley riding in from Eastern Washington. Other sources say it's the Wilburton Trestle, but the trestle in the movie is two sections taller than that one, and the angle with Mt. Rainier in the background matches the Buckley Viaduct.

This bridge was part of the NP route to Sumas that left Renton WA near Black River Junction. There are several mentions of this route in Warren Wing's NW Rail Pictorial series as well as in articles in the Mainstreeter. I grew up going past this bridge all the time in the summer when my grandparents lived in Concrete, Mt. Vernon, and finally Sedro Woolley. It has changed a lot but you can still see some of the history. Love this bridge for that reason.

Yeah, it's part of what was the Pacific Electric "Red Car's" Santa Ana branch (As was this lost Phoenix truss: ), which was built by another company in 1905 and bought by them in 1911.

Another relocated truss existed in Redlands up until it was demolished in 2012 for a UCEB:

There's a Pegram on a trolley line near LA (Red Line?). I wonder if it is also relocated.

Posted November 13, 2018, by John Marvig (marvigj27 [at] gmail [dot] com)

Clearly a railroad bridge. I would think it was built between the late 1890s and the first decade of the 20th century. It also wouldn’t be surprising if it was relocated to this location, as most railroads found reuse for spans no longer suitable for mainline use.

Posted November 13, 2018, by Luke

Possibly purchased from the Great Northern route, as that's the sole railroad the Skagit route interchanged with.

Posted November 12, 2018, by Christopher Finigan

Looks like this bridge was relocated here from elsewhere.

Goodwin Bridge (Washington)
Posted October 19, 2018, by Matt Lohry


Sadly, I wouldn’t hold my breath on this one—like 99.9% of historic bridges that are “available for adaptive reuse”, it’s likely that no one will want to pony up the hundreds of thousands that it would cost just to move this monster—that $100,000 that they’re offering would likely not even cover mobilization of equipment. Additionally, building a proper substructure to support this would cost many hundreds of thousands more; I’m sure trying not to be a Debbie downer on this, but it’s looking pretty grim for this beauty :’(

[I received the following news release today:]

CASHMERE – Slated for replacement in 2020, the nearly 90-year-old West Cashmere Bridge in Cashmere, Wash., is looking for a new home.

Chelan County, located in central Washington, is offering the historic portions of the bridge – its two 117-foot riveted steel Warren deck truss spans with verticals – to any governmental, non-profit or responsible private entity or business for public or private use.

While a small number of Warren through trusses remain in Washington state, the number of Warren deck trusses is rare. Warren trusses became popular in the late 1930s; so Warren trusses built before the 1930s are substantially more significant than those built later due to their rarity. In addition, this was about the era when heavy standard steel-rolled sections were being introduced into the design of the truss members. The West Cashmere Bridge, designed by notable bridge designer Maury M. Caldwell, is one of the last bridges standing that uses truss members fabricated via the “build-up” method of light-rolled steel sections with tie plates and lacings.

The trusses are available for donation until Jan. 1, 2019. The responsible party taking the bridge must agree to:

· Maintain the bridge and the features that give it its historic significance and continued eligibility for the National Register of Historic Places.

· Assume all future legal and financial responsibility for the bridge, including providing an agreement to hold Chelan County harmless in any liability action.

· Pay for the hauling away of the Warren deck truss spans, their transportation to a new location and their reassembling. The new owner will be responsible for determining the cost and preparing for and conducting the relocation of the bridge. The county will pay a maximum of $110,000 toward the cost of dismantling the steel trusses, but the new owner will bear the cost of removal from the site, transportation to a new location and reassembly.

More information about the West Cashmere Bridge, including its history and current condition, is on the project’s website at:

If you have questions about the West Cashmere Bridge, or would like photos of the bridge, contact Jill FitzSimmons at Chelan County Public Works at or 508-667-6415. A more detailed history of the bridge is also available at

Cited article says they plan to use a vertical lift.

Posted October 1, 2018, by Anonymous

What a shame indeed.

I do believe that Brianna is mistaken, however - the Hylebos Bridge should be safe given that it was just rehabbed recently. The Murray Morgan Bridge would be the other bridge to be considered at risk, once WashDOT is done irreversibly destroying the rare multiple-type truss bridge over on Eells Street.

Posted September 30, 2018, by Brianna Tarness (briannatarness82 [at] gmail [dot] com)

This beautiful through truss bridge and former vertical-lift bridge was demolished in 2018. What a waste. 11th Street used to continuously cross all four shipping channels along Puget Sound, but now with the loss of this bridge, only crosses two of them on each side, leaving a discontinuous route in the middle. The Murray Morgan Memorial Bridge crosses the Thea Foss Channel on the west side, and the Hylebos Bridge crosses the Hylebos Channel on the east side. The bridge over the Blair Channel has been gone for a while now, and with the loss of the 11th Street Bridge over the Pullyuap Channel, getting around the industrial flats in this area just became much more complicated, as no new bridges is planned for this location. The Murray Morgan Bridge appears to be safe for the near future, but the Hylebos Bridge is still in question. It is essential that neither one of these historic bridges be demolished, given that two of four historic bridges at this location already have been!

This might have been the bridge where a video was filmed showing an a-framed house smashing against it in the mudflow from Mt St Helens. There is an aerial photo I think of this bridge standing after the eruption of Mount St Helens with the ground covered in ash and people on it watching the mudflow in the river.

The bridge still does exsist - just under water. When Tacoma power flooded the region for the dam, they just submerged it. It’s stilll mostly intact about 80 feet (depending on water level which can vary due to how water Tacoma Power lets out of the dams.

Posted September 8, 2018, by Richard J Ehrenberg (rehrenberg [at] yahoo [dot] com)

I believe this was a concrete box beam bridge, not steel.

Posted August 30, 2018, by Luke

The steel bridges on this railroad-turned-haul-road route are all mish-mash of spans, and considering the railhead was at Rockport, a town along the Great Northern's route, I would not be surprised if Seattle City Light purchased spans from GN and reused them.

This is just conjecture, though.

Posted August 29, 2018, by John Marvig (marvigj27 [at] gmail [dot] com)

I would think this one would date to the 1890s, but the riveted connection implies 20th century. A mystery for sure. Sure a nice bridge!

Yeah, I saw the troll sculpture, and assumed no error on your part. Just curious if there was a "Troll" category when you added it as cited, and did some well meaning editor change it to "toll", or was this actually also once a toll bridge?

If this bridge was never a toll bridge, the category needs to be changed back to "Troll", and then there would be 2 - one in iowa is signed "Troll bridge".

Just for fun.

Looks like this one may be a reused swing bridge. A Northern Pacific bridge book gives a date of 1929, far too recent for this structure. Like the other trusses on this line, I would suspect this was relocated here. Fortunately, a master set of NP bridge records exists in St. Paul, Minnesota at the Minnesota Historical Society.

Curlew Bridge (Washington)
Posted April 3, 2018, by Richard Doody (rpdoody3 [at] gmail [dot] com)

Glad the confusion between the Curlew vs Orient Bridge has been resolved. They both span the Kettle River and look similar from a distance.

Back before the internet, I began looking for bridges based on the national register of historic places and was quite disappointed to find the listed Orient Bridge replaced with a concrete slab. A couple of hours later and 2 border crossings in and out of Canada, I was rewarded with a view of the Curlew Bridge.
