Covered bridges symbolize small-towns. Often called kissing bridges or courting bridges, they bring back visions of when life was simpler.
There are many tales as to the reason bridges were covered, but the truth is actually a practial one. The bridges were covered to protect the wooden trusses that held the bridge together. If the trusses were left to the ravages of weather, they would have decayed in about 10 years. When they were covered, their life span increased tenfold.
