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?
I agree with your observation, those punched handhole style plates suggest a post-1930 alteration to the bridge.
The top chord and endpost construction makes me think later than 1920. Could this have been rebuilt heavily some years after relocation?
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.
Reiterating a comment from below, that's a different bridge: http://bridgehunter.com/co/conejos/costilla/
Here's a link to an article on Lobatos Bridge. It is the southernmost crossing of the Rio Grande in Colorado.
The original picture and map location are wrong
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.
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.
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!
Forgot to comment Nice Find, JP!
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.
Continental Divide Raceways was in Castle Rock, south of Denver. I suspect that this was a go-kart track of some type.
Looking at the topographic map, the bridge may have crossed a tributary of Lake Thomas
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.
Not sure of any info on this bridge. Other then its right off the interstate and seems left to time.
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.
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.
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.
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.)
I am proud of this tunnel,as I was General Superindant in charge of the tunnel drive and concreting of the tunnel for the JF Shea Co INC .It certainly had its challenges.As the Dolomites rock is some of the hardest in America

Worst website i have ever been too, how can someone spend all their time creating a website that no one will ever see in their life. Thank you for reading this, delete your website
Visited January 20, 2018. Very cool bridge. A video in the nearby history museum of the 1965 flood shows the bridge withstanding the water. Amazing!
Looks like a Groton Bridge Company bridge to me.
This is exactly what I was thinking. these alterations would make sense to reduce a bridge from double to single track.
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.
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.
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.
Why do you post like a scene kid trapped in 2006?
This bridge is mediocre, lol hahaha laterzzz bye
There are quite a few bridges just off I 70 in this region. Colorado built some nice state standard trusses in the 1920s and 1930s.
Old Bridge just upstream
Modern = Not Historic, Not Notable, Not interesting
This bridge is also called the "Rainbow Bridge", by the locals. It is illuminated at night.
Photos are not of the correct bridge.
The photo I had previously posted here turned out to be a picture of Tunnel 39, so I moved it there.
From the pictures, it looks like someone stole the floor system. That's not good for structural stability. Very sad...
I read an article yesterday in the Reading Eagle confirming that the Winter Park express will start running January 7th.Amtrak is reporting that the trips are already sold out.Looks like snowbirds will be flocking to this resort.No pun intended.
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.
The Ski Train will resume service on January 7, 2017, running from Denver Union Station, through the Moffat Tunnel, to Winter Park Resort. It will run Saturdays, Sundays, and holiday Mondays. It will be operated by Amtrak using Amtrak equipment. https://www.amtrak.com/winterparkexpress
Replacement pedestrian bridge under construction as of August 23, 2016.
Replacement bridge construction has begun. Replacement will connect directly with I-70 WB exit ramp, allowing traffic to access bridge directly from I-70. Picture as of August 23, 2016.
Was in Glenwood this weekend and I can confirm this bridge has been torn down. New replacement is being built at this time.
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
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.
I don't think this is the correct info for Lobatos bridge (wrong picture too, as noted above). The Lobatos bridge is one lane, wood surfaced, enclosed by the supports and black in color. I'm searching for the weight limit and bridge dimensions, so if anyone can help update the record, I appreciate it. (Picture by "abravebrian" http://www.panoramio.com/m/photo/30971042)
Nice find, J.P.!
1887 railroad bridge rehabbed and used to bypass a 1924 bridge.....
Added info to the page.
I agree that your location info is correct.
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
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.
Winery nearby depicts this bridge on bottles. http://coloradowine.com/winery/black-bridge-winery/
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 :)
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.
currently in construction and scheduled to be completed November 2015 at an estimated cost of $5.8 million
I would contact City - Parks and Recreation and ask the person who answers if they book that bridge as a venue. If not, they would probably know. How cool. We love events on bridges. Take pics.
Hannah, there appears to be a Gala on September 10th for The Greenway Foundation. You could email them and ask them how they reserved the bridge.
I've seen events held here before. How do I contact someone about reserving the location? Any help and direction is appreciated. Thank you!!
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.
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.
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.
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.
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.
Denver Post story http://www.webcitation.org/6Y1F9uelm
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.
Some nice historical photos in this article
He was your Grandfather? How neat. I think this bridge is the most stunning thing I have seen in the U.S.
The marker on the map is in the wrong location. The southeast end of the bridges was located at Wazee Street and 14th Street.
Streetview confirms this bridge is gone. New bridge has some hideous post-modern columns that look sort of like arches. There is a good looking modern steel tied arch pedestrian bridge next to the new structure.
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.
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)
Featured in the 2014 Wastebook by Senator Tom Coburn.
A one page excerpt is attached.
Full Wastebook with endnotes is here:
Note that the Needle's Eye Tunnel (Tunnel 32) and the Riflesight Notch Tunnel (Tunnel 33) are different tunnels on the same route, the former on the eastern side of Rollins Pass and the latter on the western side.
This is an odd bridge! It almost can't be called a bridge as one side doesn't seem to be spanning anything. And I think it's the only pin-connected girder bridge know of. The A-frames are pin-connected and are supporting the girder.
I'd sure like to get a closer look and seem some engineering details.
This is not a photo of Lobatos Bridge.
The lodge at State Bridge, Colorado has been rebuilt, and it now hosts music festivals on its grounds in the summer. The piers of the old bridge were still visible in the river in 2012.
UP doesn't maintain the line quite as good as you might believe. They have actually removed crossing signals in some areas, and I think it has been quite a while since they have laid any ballast down. I remember seeing something about UP dumping some ballast several years ago, and I believe that was the first time they had done that in years. Also, there are many places along the line where small saplings are beginning to grow up through the ties. Nature is slowly beginning to reclaim the area, and the line has degraded enough to where it wouldn't be immediately available should the Moffat Route go down. A perfect example would be the massive washout that closed it down just recently. UP was not able to re-route any traffic over Tennesse Pass due to its current condition.
A shout out to Jeff Nelson...awesome job. Glad to see communities embracing their heritage and not destroying the past for the sake of convenience or budget. Kudos to you, the team and all parties who drove this project forward!
The project is 100% complete and a grand success. The project won an award with the APWA for Engineering and Construction.
I give a personal THANK YOU to all of the successful team, who contributed,
Jeff Nelson (Project Manager)
Assistant County Engineer
UP maintains this line yet does not use it. Not only on this site, but multiple others I have read is reports that they still send hy-rails down it at least once a year to clear rocks, grown brush and even a couple railcars of replacement ballast have been run and dropped in some areas. Also, all railroad grade crossing signals and etc. are maintained and upkept. The only thing on this line that does not function is the ancient block signals due to years of robbing parts to repair other lines.
THEORY: UP is obviously keeping this line in decent shape for a reason, either for a possible spike in business from high coal demand and insane traffic, or just simply a backup. Think about it, the Moffat tunnel is 6.5 miles long, what would UP do if something obstructed the Moffat route, such as a cave in? they would HAVE to resort to this line, its kinda like insurance.
Above all, at least they don't let it fall into disrepair. Being that the same company (Southern Pacific) that owned this line prior to the merger also owned the poorly maintained CRI&P KC-St Louis route for 16 years after recieving it, did absolutely nothing and allowed it to fully return to nature and in the end result, leaving UP with an unusable, decomposed line that would cost hundreds of millions to rebuild, yet if only cleared/checked once a year, would still be in OK shape and could be restored for far less.
Either way, point being: this line is not abandoned and maintained for a reason, otherwise they would not continue throwing money at it. There is some kind of an agenda for this line.....
I noticed Brent Tindall has adjusted GPS coordinates for quite a bit of entries lately. At first I wondered if there was an angle he was pursuing. Perhaps maybe he wanted to draw attention to something.
I think he's probably just making it so the pin is right on the bridge and not say on a reef off of the Bahamas. Some of the coordinates can be way off.
That's not to say looking around I have not found anything.
I was searching the bridge inventory for the five breakaway counties forming the state/country/kingdom of Northern Colorado. There are a few interesting ones that I added. Some rail lines pass through and there might be opportunities for rail buffs like Luke or Marvig to scan the terrain for crossings. One is present in this street view.
No the house is abandoned according to local records.
Such a beautiful part of the world...
Did you know Wiki does not recognize any info on this bridge?
The eastbound tunnel is currently under major reconstruction to widen it to 3 lanes. http://www.coloradodot.info/projects/i70twintunnels
What a relief to discover that CDOT had carefully rehabilitated these nice old bridges in 2011-12, instead of replacing them. It was such a good restoration that it had me fooled when I stopped and photographed them in June.
I just crossed these bridges in June 2013. Both original bridges are very much intact, with no evidence of construction activity to replace them, despite CDOT's schedule to replace them starting in 2011. Perhaps they figured they had higher priorities than a couple of bridges with 47.9 sufficiency ratings, very light traffic, and an alternate route for high-clearance vehicles via mainline US 50.
Traffic has just been shifted to the new bridge, even though construction work continues, Demolition of the historic truss bridge should commence soon.
I noticed that the old streetview is gone. The current view shows the nearly completed new bridge, and traffic using a temporary bridge.
