Glad I could help. I haven't done much in the way of railroad research, but it's usually pretty interesting.
Sir, I have researched a little further, and did find three articles in the newspapers of interest.
Logansport Pharos Reporter 07-28-1915: there is mention in the article that the Vandalia railroad is considering replacing the bridge over the Wabash.
Logansport Pharos Reporter 01-14-1916: It is reported that Flood waters moved the L.C. Vandalia Bridge several inches off piers.
Logansport Tribune 04-15-1916 states: The L.C. Vandalia Railroad bridge over the Wabash west of the city is now completed. The girders of the old bridge were cut up and scrapped.
I assume L.C. stands for Logansport Crawfordsville. Thanks for pointing me in the right direction. My research on the LC&SW RR is a little more complete now.
This bridge would not be from 1875 as it has riveted connections. Perhaps there was an earlier bridge at this location from that date. Or maybe you are referring to the other railroad bridge which used to exist in Logansport which was pinned and featured vertical endposts. That bridge I believe was part of the Wabash Railroad. The date I have listed for THIS bridge is 1916. Thanks
Sir, I beleive this bridge was built by the Logansport Crawfordsville & Southwestern Railroad in 1875. It was later owned by the Terre Haute & Logansport RR, Vandalia RR, then the Pennsylvania RR. Thank you for your efforts.
