That’s a great question, and one I’ve never thought to ask!
I checked the ever-dependable Wiki, and here’s what it said:
“A covered bridge is a timber-truss bridge with a roof and siding which, in most covered bridges, create an almost complete enclosure.[1] The purpose of the covering is to protect the wooden structural members from the weather. Uncovered wooden bridges have a life span of only 10 to 15 years because of the effects of rain and sun.[2]
Bridges having covers for reasons other than protecting wood trusses, such as for protecting pedestrians, are also sometimes called covered bridges.”
So there you have it.
Thank you for commenting. I learned the reason right along with you!
Thanks for looking it up. I was wondering about the function with people on my mind. But to protect the bridge itself, to last longer, makes sense. see you!
Sharon, another truly beautiful photo!
Just of interest, the entrance to our road is an 1869 covered bridge that just reopened recently (11-17) after being closed since 1985. It is wonderful to go across it after years of detouring. Here’s an article with its history for you to peruse: http://www.recorder.com/home/9383862-95/conway-covered-bridge-reopens
Hi Eliza, oh wow – thanks so much for sharing the link!
That’s a spectacular old bridge. I love that during restoration the wood was left to continue to patina naturally (it bothers me slightly that the bridge in my image is almost *too* well preserved – concrete, flood lights, perfect red siding, etc.. I prefer a more natural look. Still, I’m thankful it exists and is well tended!).
I loved the image of the two ladies crossing the Conway bridge. What a terrific way to honor its history.

I was wondering why a roof on a bridge? Nice capture; see you.
