What can be 100 years old, has a roof, usually has a single lane, and spans a body of water? If you answered a covered bridge, you are correct. Covered bridges are pieces of history that many times are located in scenic locations.
The purpose of a covering a bridge with a roof and sides was to protect it from the weather. It was mainly to protect the structure that supported the bridge. Without covering, the bridge might last 20 years, while covering it translated into the bridge maybe lasting 100 years.
Other states have more covered bridges, but Vermont can lay claim to having the most per square mile over any other state. Vermont has more than 100 surviving in total. Some you can still drive over, others you can walk over. There are sites online that recommend short driving tours that include a few of them. Some towns have more than one covered bridge. I found two in the Grafton area. According to Wikipedia these are the towns with 3 or more covered bridges: Bennington (3), Charlotte (3), Randolph (3), Cambridge (3), Waterville (3), Pittsford (4), Northfield (5), Tunbridge (5), Lyndon (5),and Montgomery (6).
There are websites that list locations and provide a map detailing where some of them are. I recommend this website :

When I think of autumn in New England it conjures up memories of pictures I have seen in travel articles featuring covered bridges and fall foliage. It is fun to scavenger hunt in fall and winter for covered bridges in Vermont. If you are visiting Vermont or traveling through, try to locate one.
