Which is the Standard Bridge Number Board........this example showing the number being from the period of UP ownership.

Huh.  Is that (the bridge/trestle number board) something that continued on into later years?

[Chris Walker]

I should have been clearer, meaning the Number was from the UP period as UP/C&S had number changes from the original CC.

A quick look through Colorado Central Rail Road by Abbott/McLeod shows at least 8 on the Clear Cr. line surviving through to the 1939 Survey, others like the Steel Truss got the number painted on the Vertical Chord.  Others seem to have nothing.

Even on the Sth Park as late as 1941, legibility a moot point.

Thanks, Chris.  None of my bridges or trestles are direct copies of prototype examples, so whatever was “reasonably common” is good enough for me.

Cheers,
Jeff.

That's the beauty of "variation on a theme", the C&S was nice enough to provide the Modeller with all the variation he needs whether it be 9 variations of boxcars or differing airtanks on each locomotive or something more mundane such as the Bridge numberboard.  You just didn't get that variation on such a scale as with the Grande :)  

More on the Platte Canon #boards....the Trestle over the Hoosier creek at Webster still had a visible # during scrapping of the line.  R.B.Jackson photo, Pg182 of Mal Ferrell's C&Sng.  Oddly there seems to be no "standard" to locating these either, most seem to have the board located on the Abutment while Gold Pan trestle has it on the second Bent,  also note that the most prevalent location is on the Enginedrivers side going away from Denver, both Clear. Cr. and Sth. Park lines.   If anyone has seen a difference to this "standard" in a picture (other than Beaver Brook and the 1/2 at Golden),  please post it!

On pg33 of Digerness's The Mineral Belt V-2, in a John Maxwell photo of C&S#70 backing up past Strontia Springs shows this post-1900 view to still be the case.

And one I didn't notice hiding in the shadows at Beaver Brook

Interesting that the stone abutments for bridge 604 1/2 still exist in Golden. This bridge is located right behind the Golden  Community Center off (or under) Eight Street.

[Chris Walker]

Jeff, are you meaning that the Street over that ditch is on the C&S abutments or adjacent to?  I just had a "lookie" on Streetview and can't see any abutment in the weeds.

Interestingly that 604 1/2 isn't listed in the Bridge data in the CCRR book by Abbott/McLeod on pg62 and I haven't seen this photo published anywhere else in the Major C&S/CC books.  It maybe in some lesser known publication about Golden and/or the CSM, I have yet to discover, so basically this is new information presented here.

And while I'm here, another non-standard, centrally located Bridge numberpost.

[Jeff Young]

What was the numbering scheme?  I thought at first they were by mile-marker, but 604 doesn’t really sit with that.

(If they’re different by road, I’d be most interested in the Denver - Leadville scheme.)

Cheers,
Jeff.

This 604 1/2 bridge is an enigma, I had hoped Rick Steele would chime in on this.  

http://digital.denverlibrary.org/cdm/singleitem/collection/p15330coll22/id/8116/rec/132

Abbott/McLeod's Colorado Central  Rail Road says 1st bridge out of Golden was a single span 16ft culvert over the Ralston Ditch numbered Br No.1 Colorado Central(1872) , under UP(1886) renumbered as #601.  There on pg58 is a photo of this Bridge No.1 taken  from the same bank but on the Southside looking North.  Those banks in both photos show the same or similar stone lining.  By the time of the C&S Valuation survey picture shown, the Marker has migrated back to the Dumpboard.  Again, there is no mention of this 604 1/2 Bridge in Colorado Central RR.

Which begs the Question:
Were there additional Ditch Bridges built following the 1886 renumbering?

As the bridges were numbered consecutively Golden to Central, with another sequence from the Forks to Barkerville.  The Wooden truss Forks Creek Bridge was CC No.1 (as well) becoming #701 under the UP.  

This Sundance book doesn't actually state whether the C&S continued the 1886 (UP) numbers or reverted to a M.P. based number on the Clear Creek line.   Relating to this is a mention on pg64 that the Culvert Bridge upstream of Bridge No.7 built after 1886 had legible lettering still visible that read 17.47.

The #39 post at Stanley Mills I mistook for the Truss-rod Bridge # (no number visible on the Bridge itself) is actually the Milepost 39, from what I can deceifer from CC RR is the C&S Valuation survey of 1939 lists bridge numbers as per milepost  eg 39.01 at Stanley Mills. 
 
A conflict of numbers for this structure is on pg321 showing on the Don Griffin map as Bridge No.13 and pg324 in the photo caption as Bridge No.16 (1886 number 716), the aforementioned M.P.39 signpost not helping here.   An aside, Br. No.13/713 should be located back between the Dewey/Kilton Sampler and the Chamberlain/Wiley Sampler mills.

If there is a pair of bridges, these were numbered such as #712A&B at Virginia Creek, a pair were also at Elk Creek.  I haven't seen anything in written form, presuming the A for the Mainline and B to relate to the sidetrack at those locations.  

The fact that nearly all the pictures show a severely weathered numberboard doesn't help matters here.  The same goes for the South Park photo's, nothing legible to show numbering apart from an undated photo North out of Como before the Highline pg99  Mineral Belt V-2 which delightfully shows 68.76, a Mileage based system.  Note on this trestle (and on the Truss at Stanley Mills) the Guard Timbers are not Dapped(Dabbed depending on your Carpenters lingo).  These were a row of Dadoes cut to fit the locations of the Crossties thus locking the Ties in place reducing the number of Bolts required.

Finally found a clear shot of Gold Pan trestle (no inner guard rails; 1938):

Cheers,

[Robert McFarland]

Which video had the color film of this move?

[Jeff Ramsey]

Notice the caption from the Mineral Belt II is wrong as I think this bridge, 68.76 was more like around Grant.

Looks like within the last 4 years the City of Golden was reworked the north side of the bridge on 8th street, replacing it with a modern concrete abutment and truss. I wished I would have taken a photo a few years back but that is how the story goes... A image is provided how it looks today. On the south side of 8th street there is a old corrugated steel pipes set in concrete but I did find a little bit of C&S or earlier rock work still intact. Rare that this stone work is laid wet or with mortar.

[Ken Martin]

I was going through a book of sign data sheets from the Burlington Route Historical Soc. and found this data sheet for C&S Bridge number signs and remembered this thread. I did do a little clean up of the drawing.

[Chris Walker]

And one more for the road...

Love the lettering on that one.
