South Fork Pottawatomie Creek Bridge

I am not certain if federal funds are being used for this project or not. I have tried to find an article about the replacement, but I have had no luck so far. Based on NBI data, the deck width is the main issue with this bridge. This is no surprise as the deck geometry, not the structural integrity is why many Marsh arches get replaced.

Naturally, Sec. 106 does not apply to this bridge as it is not on the NRHP. According to the latest NBI information, it is possibly eligible. It is my understanding that KDOT and KSHS are working on surveying potentially historic bridges again, but as of now, they are working from historical surveys conducted in the 1980s. At that time, there were roughly 76 Marsh arch bridges remaining in Kansas, but that number has been reduced to roughly 29. At least two of those bridges, and possibly a third will be demolished in 2012.

It is my observation that this replacement is not only destroying an extremely rare bridge type it also is completely unneeded and a massive waste of tax payer dollars based on traffic volumes, deck width, and structure condition. I also find projects like this suspicious when the sufficiency rating is only 2 or less points away from the threshold of getting federal replacement funding. How convenient that all those inspection reports, equations, and variables all just happened to calculate just enough so that it could be replaced. Although there are rigorous standard and processes for bridge inspections, there is a small amount of subjective flexibility, enough that I suspect it would be possible to "tweak" results to something favorable by someone seeking replacement funding.

Or am I jumping to conclusions? Is federal funding even involved here? Or does Kansas do like Michigan and use state funds only for bridge projects, conveniently bypassing Section 106? I assume this bridge is eligible for the National Register. If it wasn't considered eligible, the finding is either outdated or conducted by someone inexperienced in historic bridges.

Another Marsh arch bites the dust...
