This tiny bridge was distinguished as the oldest stone bridge in the state, with a c. 1790 construction date. This was one of the oldest stone bridges in the country, and as such it was an extremely significant bridge despite its small size. The bridge was bypassed in 1915. After standing the test of time for roughly 220 years, this bridge was destroyed in the record floods of March 2010.

While seriously damaged, the bridge still exists--barely. The arch facing Lower Blissville Road is complete. The deck is gone, as well as the other arch.

In the Google Street View dtd 9/2013, the stone arch is present just north of the road. Either someone is trying to rebuild it, or remnants of the bridge still remain.

I did play under the bridge when I was young. I lived next door and my friend lived on the property where the bridge is located. In the summer, when the water was low, we splashed and played beside the bridge. We seldom ventured under the bridge because it looked spooky to us. My brother had told me the bridge was an historical landmark but I never realize the importance till the flood and I read about it in the paper.

A ten-foot stone bridge...I would have loved to play on this as a kid. Shame it's gone.
