Hey, We have an RV lot at Flint Ridge Resort. We discovered this bridge in 2009 and drive across it and take pictures often. We assume this bridge may have preceded the old Highway 33 bridge to the South but we do not know. We love these old bridges and I love to drive across them. Now for the downside: My wife and I drove our golf cart to this bridge on 4-20-2020. My wife wanted to take some pictures so I sat on the golf cart in the middle of the bridge while she walked around on the bridge and snapped pics. I was shocked ! every step my wife took, shook the whole bridge ! I could not believe what I was feeling. I encouraged her to hurry and as soon as she got on the cart, we were gone. I will not even walk across that bridge again.
We live right here. The bridge is super stable - engineers came out and verified very recently. Perhaps you visited when the water was high - seems like it might have been on that date. When the water is high you can definitely feel some slight movement.
