    I'm trying to figure out what kind type of bridge this is. There are three sections and has two types of construction.

    I've provided a capture of the notes from the Clinton Sub bridge record document for this bridge.

    Thanks for any help.

    I'm taking a stab because it's a little hard to read but I think you have two end segments that are "Wood Stringers" on Masonry piers. In the center, some sort of Pony Truss, but this is the part I can't read very well.

    Bob is correct.

    Wood stringers on masonry piers. The center structure is a 86 foot, pony riveted truss (PRT). The span covered by the wood stringers would be on the order of 13 to 15 feet.

    Thanks guys. What about a T.R.T bridge? What does that stand for? I'm specifically thinking of bridge 114.4 just north of Osceola. The one that crossed Gallnipper Creek.

    Perfect thanks Karl.

    I hate to be a pest but I was wondering if you could post an older topo map of the Highline north of Osceola. One that would meet this one to the north.

    Map shows just north of Osceola, MP 112.2, MP 115.1 (KCCS) to just south of Harlan Junction, MP 115.2 , MP 118.1 (KCCS).

    I want my v-scale route to be as accurate as possible but I'm having a hard time getting any data on roads, creeks, and topography for this area pre Truman Lake reservoir.

    Attached are images from the Lowry City 7-1/2 minute Quadrangle (1941), which is the quad north of Osceola.

    Between Dejun and Lowry City Junction the Frisco ran on the Leaking Roof (KCCS). South of Lowry City Junction the Highline returned to the KCOS track. On the attached maps the abandoned KCOS is depicted by a red line, and the abandoned KCCS is depicted by a blue line.

    The digital topo sheets have been laid atop of the Google Earth images.

    I have to digitized the northern piece of the Osceola Quad to fill the rest of your gap.

    Thank you. These will be very helpful.

    I've really had trouble trying to identify landmarks in the attached area due to all the present day flooding. Would you have a old topo map of the area where the SLSF and KCCS crossed Gallinipper Creek out of Osceola?

    Sorry Karl. I got in a bit of a rush and misread your post.

    Here's the NW quarter of the Osceola 7-1/2 minute topo sheet, which has a publish date of 1939.

    The flood pool for Truman reservoir is 739.6 feet, and conservation pool is 706 feet.

    Thank you Karl. Very much appreciated. I can put this to good use.

    The US Geological Survey has just recently (January 3, 2012) posted the topographic maps for Missouri on its website.
    According to their availability page they have 3,572 maps for Missouri posted, including 2,703 1:24,000 series and 583 1:62,500 series quads!!

    They now have coverage of the "standard" topos for every state the Frisco served except Mississippi (schedule for January - March 2012) and Florida (scheduled for April-June 2012).
    "Non-standard" topos - whose coverage is different from the normal 7 1/2' x 7/12', 15' x 15', 30' x 30', etc. are to be available in the summer of 2012. Unfortunately these include St. Louis and the Joplin area, both very important areas to the Frisco.

    Included are the 1880-1890's vintage 30' x 30' 1:125,000 reconnaissance maps which cover much (but not quite all) of eastern Missouri and eastern Kansas, the 15' x 15' 1:62,500 series maps from the 1900s into the 1970s covering bits of southeast Kansas and much of eastern and southeast Missouri and northeastern Arkansas, along with the 7-1/2' x 7-1/2' 1:24,000 maps of just about everywhere from the 1930s to the present.

    The Clinton 30 x 30 is available in 1887 and 2 1894 versions, and Stockton 30 x 30 south of it had 3 versions marked 1886, while Bolivar 30 x 30 has no less than 6 variants, one dated as 1884 and the rest as 1892.

    The Lowry City 7-1/2' quad has 3 versions marked 1941, 1 marked 1945 and 1 marked 1991, plus the Digital Map Beta of 2009 and the US Topo dated 2011. They are sizable files, from 12.6 to 19.7 megabytes. The 30x30 mostly seem to run around 6 megabytes.

    The Osceola Quad has 3 versions marked 1939, 1 marked 1940, plus the Beta and US Topos.

    No, I can't say I really understand the system USGS is using to identify the date on all these maps. There are also some odd skips in the coverage but it is still a wondrous resource for tracing old railroads.

    As an example of the oddities, Vista shows only a 1991 7 1/2' quad (and the usual Beta and US Topo maps) even though I have some Xerox copies of part of a Vista quad dated from ca. 1940 that I made years ago at the Northwestern University Library. T

    The Maps of Missouri website at St. Louis Public Library at also shows some 15 x 15' topos that the USGS website doesn't show in its list.

    Here is a 600 dpi scan of a portion of an aerial photograph from the survey of Henry County in 1952. It is from sheet BF-3H-49 photographed on 05-12-1952.

    BF-3H-49_MP-D-92 area-600dpi.jpg

    And here is a 2400dpi scan of the bridge itself.


    And here is a 600dpi scan of the area from the Grand River bridge south almost to Brownington, from sheet BF-3H-51 of 05/12/1952. Note the long trestle about halfway between the bridge and where the highway crosses the railroad.


    Fishing maps of Truman Lake have a warning about this stretch of the roadbed, which sits just under the lake's normal level.

    And a 2400dpi scan of the Grand River bridge and the adjacent highway bridge.

    Thanks again. Are these photos also from the Henry County Library?

    The library, which is where I work, has complete coverage of the entire county. The mosaic which shows the entire county in reduced form identifies many more pictures than we have at the library. Not all the photos overlap; but, the overlap is so great that with us having about every alternate photo, every location is covered in at least one and often 2 or 3 photos.

    If you are interested in seeing other areas I can easily scan more. I've already got some Deepwater stuff scanned and can put it up when I get some more time.

    That would be great. The areas in question for me are the areas that are now flooded. Maybe I could stop in sometime and see you at the library.

    I posted a question for you on my MKT in Clinton thread. Are the MKT valuation maps from 1918 or 1970?
