Old Wire Road Tunnel
Posted June 7, 2006, by Colin Campbell (cmcampb [at] adelphia [dot] net)

I was in Siloam Springs last week with my mother, Doris Harman Kessler, and we were looking for structures built by her grandfather, Willis Tweed Harman, who lived in Siloam Springs. She remembers that he built the first dam in Siloam Springs to make a pool of the two springs there, and that he worked on the construction of (she thinks) a narrow gauge railroad, which might have been nicknamed "Peavine". It might have roughly followed the route of the present Arkansas & Missouri RR.

He used to put the name "Harman" in the concrete structures he built. I wondered whether this railroad bridge, or any other bridges or viaducts in northwest Arkansas are known that show the name "Harman".

If anyone knows of structures with the name "Harman" on them, we'd sure appreciate hearing from you!
