DSP&PRR Bridge Research.

[Chris Walker]

A little something new, as in an "unpublished" view.
Actually not that new, I found it back in 2017, and only due to a recently revived thread on the NGDF that had a reference to an ancient post of mine on there, was I reminded of this "to do".

Located in Platte Canyon, upstream from Crosson's is one of the South Park's many crossings of the South Platte.



Rick Steele provided the B&B list http://c-sng-discussion-forum.254.s1.nabble.com/Two-Railroad-Rosters-tp14478p14556.html

Denver Public Library Photo X-13507


Jim Courtney uncovered the R.B.Jackson album http://c-sng-discussion-forum.254.s1.nabble.com/Richard-B-Jackson-s-South-Park-Photo-Album-tp18596.html
that had this "modern" image from the R.B.Jackson album.


Enlarging the DPL X-13507 shows us some detail of the early bridge construction, mentioned in the Miller 1883 B&B.
Note that at that time there were no portal braces, and the Truss had approach deck spans and trestle supports.



Buried in the bowels of Princeton Uni Library is this W.H Jackson image.


Enlarging this wonderful image revealed even more detail of the bridge; portal braces and the  Stone Piers noted in "Miller 1883".
Note the lower chords are Iron; Todd Hackett discussed this early construction http://c-sng-discussion-forum.254.s1.nabble.com/Wood-truss-bridge-at-Forks-Creek-tp19773.html



Sorry this took so long, but it great to bring new material to the fore, even at this late date.
