This map is from a guidebook I put together for the DSP&P Historical Society convention in 2017, showing historical items traced from the 1919 ICC maps and the present highway configuration:
I started this thread on the original wood truss bridge. The Campbell is a more traditional Howe truss, and other than being a through truss bridge with some wood, it's not very similar to the original bridge at Forks Creek. Since starting that post, I realized that what I had labeled as the "Main Tension Rods" are actually rectangular bars while what I labeled "Intermediate Rod" are probably the main tension rods as each has a turnbuckle. The rectangular bars are in pairs, with the bottom apparently attached to the pin joint, and I haven't figured out how the tops are connected, but possible there's some sort of casting at the top of the wood diagonal members that includes that connection. This photo from DPL shows these pieces:
Note that the later steel truss bridge replaced this bridge in 1891.
