James,
Thanks for sharing the information on these bridges.
I might note too that this bridge is one of the 3 Daniel Luten designed bridges in Cass County, built to replace structures lost in the great flood of 1913.
This is known as the old "Cass Station Bridge". Bridge is a popular fishing spot, when it is mowed that is. I live a half mile away and use the bridge occasionally while biking. There is a hole forming on the South side of the bridge about 30 feet from the South approach on the West side of the bridge next to the sidewall. Vegetation grows very well over the old asphalt, as seen in the photos above. Check out the huge rock formation, the Council Rock, off of the old road that ends at the South bridge approach. This was a Indian gathering place, as well as French traders, who noted it's unusual appearance way back in the 1700's. The Cass Station moniker comes from the old Interuban line that at one time passed just North of the bridge, featuring a station stop nearby called of course Cass Station. The old ROW for that line is now "Coonhunter's Road". CR 600 East will be under reconstruction starting Spring 2008, lasting until November 2008, so be aware. The bridges will be uneffected.
