This next mystery bridge keeps us in Idaho but we go to Ada County and to this bridge, spanning Indian Creek at Black Cat Road. The bridge is a sloped, camelback Parker through truss bridge with Howe lattice portal bracings, supported by heels. The truss bridge has six panels and all the beams are pin connected.
Bridgehunter.com has little information on this structure except for its location and the Street View. Unfortunately no other photos or information on the bridge were found. Hence the screenshot to give the readers an idea what the truss bridge is like. This structure is unique for it is one of the last truss bridges in the US, whose upper chord is sloped all the way to the portal bracings. Dozens of these bridges were built until 1910, when standardized trusses were introduced. Which explains why this bridge, which is between 100 & 150 feet long was built between 1890 and 1910.
The bridge has been bypassed for a couple decades, still it has historic value which warrants its nomination to the National Register. What’s missing is the information on its history, combined with the dimensions.
This is where you step in. Got any facts about the bridge? Then post them here as well as in the bridgehunter.com website. The more facts, the more likely it will be on the NRHP. And the more likely it will be used in the future as a recreation crossing.
Good luck and happy bridgehunting. 😎
