Clark,
Do you know how much of this bridge is being replaced?
When younger I wondered why this bridge is so plain compared to the KCS concrete arches built over Wildcat Hollow, Gregory, and of course US 50 (now Blue Parkway). The 1931 county road map gives the answer. There was no road passing under this bridge when it was built. Swope Parkway was the eastern end of 63rd St when this bridge went up over an essentially empty valley.
Awesome!!! There are 3 more KCS bridges in the KC/Grandview area that you could photograph: 1) the concrete overpass just to the west of E. Stadium Rd, 2) the concrete/steel deck girder bridge that crosses over I-435 outside of Grandview, and 3) the steel thru-plate girder bridge in Grandview that crosses a street and rr tracks. This one used to be silver/brown or black; now, it has been repainted. I am not sure whether the western-most span crosses a side access road or rr tracks. It is difficult to see due to foliage.
One piece is up and one staged below. Next time I pass I'll see if there's someone who knows. Just a clean-up guy on an excavator when I visited yesterday.
