James, could you link the builder Martin added with like each iteration of King is linked?

More people are going to know it by the older name vs the post-1929 name used on this bridge.

Being used by pedestrians doesn't always mean legally open to pedestrians. :')

Closed to pedestrians, but the photograph shows people walking on the trestle. Closed or not?

Thank you.

Not necessarily Nick. I have seen many state highway design ponies in Indiana from the 1930's that have them. Of course these built from angles are far less interesting as the fluted cruciform ones from the 1870's-1880's!

Posted August 11, 2019, by John Marvig

Considering itís relocated, could this be an old railroad bridge? It seems to have a very similar design to this overpass in Missouri:

Heading towards Gilman on the rail line that I was following on satellite I saw a lot of landslides on the tracks.When and if they use this rail line ever in the future they'll have some rocks and dirt to remove.

This bridge was resurfaced. The original railing is gone.

I'm slowly tracking down information on the bridges.

LostBridges gives a ca. 1889 build date for the uncovered wooden Howe truss, and both the Lake City Museum and a DRGW railfan state that both the bridges were torn down in 1937,254044,254087#msg-...

I've yet to find a build date for the steel truss, but based on this picture: it's probably from the same era and this similar bridge:

A Colorado-specific trade magazine gave info for the arch and a build date for the old road, though we still have no clue about who built the pony truss.

Right below the name of the bridge (top of the page), you should have a series of options, first one should be to upload photos. Is there nothing there?

How do I add a photo to a particular bridge? I don't see that it gives me that option.

Posted September 19, 2018, by John Marvig

It looks like the 1920 date is a typo and it should be 1902. I would also agree. Perhaps the bridge was rebuilt in 1902 using secondhand material, and rebuild again in the 30s or 40s?

Posted September 18, 2018, by Nathan Holth (webmaster [at] historicbridges [dot] org)


I agree with your observation, those punched handhole style plates suggest a post-1930 alteration to the bridge.

Posted September 18, 2018, by Clark Vance (cvance [at] dogmail [dot] com)

The top chord and endpost construction makes me think later than 1920. Could this have been rebuilt heavily some years after relocation?

Posted September 18, 2018, by John Marvig (marvigj27 [at] gmail [dot] com)

This article provides a great insight on the relocation process, including the "splitting" method used on trusses and girders. It makes specific mention of pin connected trusses rebuilt in this manner, such as this bridge.

Is this possibly an old railroad bridge the company bought and reused?

Continental Divide Race Park, north of Denver near Mead.

Continental Divide Raceways, South of Denver near Castle Rock.

Posted May 14, 2018, by Luke

I have no doubts about the bridge being relocated here 1999.

Several tracks have relocated bridges. Most notably Lime Rock Park's ingress/egress Bailey truss and the former Bridgehampton Race Circuit's still-extant Chevron ingress/egress Bailey bridge.

Posted May 14, 2018, by Ed Hollowell (erhollowell [at] aol [dot] com)

Guess your right. From looking at the photo I'd have thought that it was much older. I would avoid the contractor who paved that place. It looks at least 40 years old yet it was paved in 2000!

Posted May 14, 2018, by Luke

Forgot to comment Nice Find, JP!

Posted May 14, 2018, by Luke

This track was also named Continental Divide (After initially being called Mountain View Motorsports Park). It was at one point owned by the owner of the Utah Jazz NBA team before he abandoned this track for one near Salt Lake City.

Posted May 14, 2018, by Ed Hollowell (erhollowell [at] aol [dot] com)

Continental Divide Raceways was in Castle Rock, south of Denver. I suspect that this was a go-kart track of some type.

Posted May 14, 2018, by David Backlin (us71 [at] cox [dot] net)

Looking at the topographic map, the bridge may have crossed a tributary of Lake Thomas

Posted May 14, 2018, by M C Toyer (mctoyer [at] hotmail [dot] com)

The aerial view shows that bridge to be over one leg of an abandoned race track or auto test track so presumably the bridge was relocated there. That might be more interesting than the bridge itself.

Posted May 14, 2018, by J.P. (wildcatjon2000 [at] gmail [dot] com)

Not sure of any info on this bridge. Other then its right off the interstate and seems left to time.

Posted May 7, 2018, by John Marvig (marvigj27 [at] gmail [dot] com)

Curious to the 1935 date. Where did it come from? The latest built railroad stone arch Iíve seen is 1919, but I know the design was superceddes by concrete around 1900.

Posted April 19, 2018, by James McCray (jamesinslocomb [at] yahoo [dot] com)

Any clue about this bridge? Seems historic, but newly relocated to this place.

In image 2 the Wewatta bridge is the one in the far distance at middle right.

Posted March 10, 2018, by Jim Eager (jeager [at] sympatico [dot] ca)

Sorry, I mixed up the compas direction of the Wewatta St bridges: The C&S bridge (removed) was to the north, the D&RGW bridge (existing) was to the south.

Posted March 10, 2018, by Jim Eager (jeager [at] sympatico [dot] ca)

You have conflated two different bridges here.

Images 1 and 2 are of the north* Wewatta St bridge, which carried the D&RGW main line across Cherry Creek to/from Denver Union Station. Image 2 was taken from the Wynkoop St bridge.

Images 3 through 8 are of the Wynkoop St bridge, which carried a D&RGW switching spur north across Cherry Creek to run along Wynkoop St.

(*The south Wewatta St bridge was removed. It carried the C&S main line across Cherry Creek to/from Denver Union Station.)

Looks like a Groton Bridge Company bridge to me.

Posted December 11, 2017, by John Marvig (marvigj27 [at] gmail [dot] com)


This is exactly what I was thinking. these alterations would make sense to reduce a bridge from double to single track.

Posted December 11, 2017, by Robert Elder (robertelder1 [at] gmail [dot] com)

The vertical members are lightweight built-up members which I would anticipate seeing on an 1883 Bridge. The sway bracing is composed of large rolled beams which I would not anticipate on an 1883 bridge.

Posted December 11, 2017, by Robert Elder (robertelder1 [at] gmail [dot] com)

For a bridge that was constructed in 1883, this one is very heavy even by railroad bridge standards.

I suspect that it might have had some parts replaced when it was moved. The portal bracing and much of the lateral bracing looks a little heavy for 1883 even though this is a railroad bridge. Railroad bridges often had portal bracing replaced as trains got taller so this would not be a surprising alteration.

Posted December 10, 2017, by John Marvig (marvigj27 [at] gmail [dot] com)

According to an annual report from 1883, the bridge was built double track. It appears that it was cut down in 1902 to a single track, including rebuilt portals.

To be put in storage in Montezuma County. From article:

County planners said they have agreed to take the structure and plan to store it at the fairgrounds. One potential use for it is on the proposed Paths to Mesa Verde project, a proposed 17-mile nonmotorized trail connecting Cortez and Mancos to Mesa Verde National Park.

It could be used as bridge to connect the trail across U.S. Highway 160, including to the Philís World trail system or Southwest Colorado Community College. It may come in handy for getting the trail across McElmo Creek or irrigation canals within the proposed trail corridor, which includes both sides of the highway.

Was in Glenwood this weekend and I can confirm this bridge has been torn down. New replacement is being built at this time.

Posted September 15, 2016, by Matt Lohry

Being the bridge is fairly new, it was likely designed and built to exceed new Colorado standards, which I believe are 40 tons for single-axle vehicles and 42.5 tons for multi-axle.

What is the weight restriction on this bridge

Posted September 13, 2016, by Roger Deschner (rogerdeschner [at] gmail [dot] com)

Visited in July 2016 and took some pictures. Track appears somewhat maintained, with evidence a hi-rail vehicle has been through here recently. So UPRR has not completely abandoned this line (yet). However all signal systems have been dismantled. The south portal is easily reached on a public county road, from US 24 just south of the pass.

Thanks Jayhwk;

Added info to the page.

I agree that your location info is correct.

Posted January 15, 2016, by jayhwk

This bridge was built by the state of Colorado for $4,000 with Lake County contributing $223.80 and was completed October 15, 1908 by the Pueblo Bridge Company. It has two 35' Luten arch spans:

There is a photograph a couple pages down in the document.

As far as the location goes, I submit this for consideration:

County Road 10

Leadville, CO 80461

39.164010, -106.319801

I can check next time I'm in the area and get a couple photographs, but it would be great if an editor could update the page with the other info.

According to Silverton Public Works this bridge was scrapped and locals mostly oppose replacing it in order to limit through traffic in their area.

Nice work solving the mystery... as for categorization, I guess its a matter of opinion... its mostly a deck girder, but could be called a through, if barely. Even though its technically not a "plate" girder, that's probably OK to list it as that. I ran into a similar problem on my own website with a similar bridge in Canada... and I was too lazy to create a separate category :)

Posted October 23, 2015, by Roger Deschner (rogerdeschner [at] gmail [dot] com)

Nathan, you're right, and I was able to revisit the bridge and look underneath to confirm and get a picture. (photos above) The creek was running high, so the only way to get a picture underneath was to dangle my phone on a "selfie stick". (Useful when you have neither fishing waders nor a drone.) The photo revealed an unusual jack-arch deck.

Unfortunately, there is no category here for girder/floorbeam system bridges. Should this really be some kind of a pony girder bridge, since the support beams are higher than the deck? No category for that either, since the support girders are not composed of plates. I'll leave these questions of taxonomy to others; I took the pictures.

As of 7/24/15 the river channel has been re-routed in preparation for replacement of the eastern most span. New steel beams have been staged in an open lot to the north of the highway east of the bridges. Would assume that all three spans are to be replaced. Curious what will be done with the old bridge structures.

Posted July 22, 2015, by Roger Deschner (rogerdeschner [at] gmail [dot] com)

The Riflesight Notch Loop was planned and built as a single structure by the railroad for the purpose of gaining elevation in a limited space. To do that they had to build a tunnel and a bridge (trestle), together at the exact same location. (See photo) They probably had to be built very carefully, to avoid one damaging the other during construction. Historians consider them as one structure. If they were to be considered separately, they would have the exact same geographic coordinates. I do not see how that is different from the Navy requiring a string of bridges and tunnels to traverse Chesapeake Bay. That is why I tagged Riflesight Notch Loop as a bridge-tunnel, because that's what this single structure is. I have been to both. If Riflesight Notch Loop is two separate structures, then the Chesapeake Bay Bridge-Tunnel is several separate structures as well, related as "same project". It has 15 separate Virginia Bridge Numbers. For simplicity, let's just keep both bridge-tunnels as single entities here.

Posted July 22, 2015, by Luke

The category was made for three structures at Norfolk/Virginia Beach/Hampton, Virginia that are bridges with tunnels underneath the main navigation channels.

The structures were built that way due to the Navy being worried about a bridge being targeted to shut down the navigation channels, thereby crippling the Atlantic Fleet, which is based out of Naval Station Norfolk.

Posted July 22, 2015, by Patrick Feller (nakrnsm [at] aol [dot] com)

Much as I'd like to see a bridge tunnel or a trestle tunnel, this trestle and tunnel appear to be two entirely separate structures, functionally and structurally independent of each other.

Posted July 22, 2015, by Chester Gehman (gehmanc2000 [at] yahoo [dot] com)

We have so many meaningless categories on this website I have to ask: what is a bridge-tunnel? And if Tunnel 33 does not qualify, according to our expert, what is it? A trestle-tunnel?

There are reports that the Ski Train may resume service through the Moffat Tunnel carrying skiers from Denver to Winter Park Resort on winter weekends, starting this coming winter. The Ski Train had run on this route from 1940-2009. A trial run in March 2015, using Amtrak equipment, sold out in just hours. Details, including approval by the Union Pacific Railroad, are still being worked out.

Skiers are desperate to escape traffic congestion on I-70, so the movement to restart the Ski Train on the Moffat Route is gaining quite a bit of momentum. It's a 2-hour train ride, about equivalent to driving via I-70 if there were no traffic, but on winter weekends I-70 is typically very badly congested.

Posted May 25, 2015, by Nathan Holth (webmaster [at] historicbridges [dot] org)

I think this is actually a girder/floorbeam system type bridge. Note how the outer beams rise above the roadway level, and further note the rivets in the side of the girder, which one would assume, are where the transverse floor beams are riveted.

Just an observation:

Noticed while white water rafting June of 2014, that, in many places, farmers have put up fences directly across the line. A couple of them actually had gates across the tracks but others appeared to be permanent fences.

Posted November 6, 2014, by Nathan Holth (webmaster [at] historicbridges [dot] org)

Wasteful indeed. Its bad enough we waste money in this country demolishing and replacing historic bridges used by 10 cars a day when they could be repaired for far less money.

And its very stupid to consider the use of a small amount of Canadian Steel as detrimental to the US economy... there is a big difference between importing from Canada and importing from China. Think of the millions upon millions of dollars of low-grade Chinese steel used to replace the Oakland Bay Bridge in CA... which supported an economy across the seas that will have little return benefit to us.

Canada in contrast provides the USA with numerous economic benefits. Whether its the massive numbers of Canadians that stream across our border in large numbers and go shopping on a daily basis, or the fact that Canada has for over 100 years used steel from the United States on a very large percentage of its bridges. (the other two sources were traditionally various mills in the UK and Algoma Steel in Canada)
