Covered bridge

A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. The purpose of the covering is to protect the wooden structural members from the weather. Uncovered wooden bridges typically have a lifespan of only 20 years because of the effects of rain and sun, but a covered bridge can last over 100 years. In the United States, only about 1 in 10 survived the 20th century. The relatively small number of surviving bridges is due to deliberate replacement, neglect, and the high cost of restoration.

The Bridges of Madison County is a 1992 best-selling romance novel by American writer Robert James Waller that tells the story of an Italian-American World War II war bride living on a farm in 1960s Madison County, Iowa. While her husband and children are away at the State Fair, she engages in an affair with a National Geographic photographer from Bellingham, Washington, who is visiting Madison County to create a photographic essay on the covered bridges in the area. The novel is presented as a novelization of a true story, but it is in fact entirely fictional.
