Enjoyed this article explaining the main reason #CoveredBridges are covered: to protect the important parts of the bridge from rotting (NOT, as I'd supposed, to keep the roadway free of ice and snow).

My picture shows the interior of our local one, the #Dummerston Covered Bridge, across the West River. Many of my summer bike rides take me here and beyond. #Vermont
