Covered bridges in North America

Such bridges are found in rural areas throughout the United States and Canada, but are often threatened by arsonists, vandals, and flooding. They are also common around eastern Canada and in the United States in places such as Chester County, Pennsylvania and Lancaster County, Pennsylvania, Lane County, Oregon, Madison County, Iowa and Parke County, Indiana. Parts of Ohio, Michigan, Kentucky, Maryland, West Virginia and the New England states also have surviving covered bridges.

There are various structural designs used for covered bridges, such as the Burr arch.

Opened on July 4, 1901, the 1,282 foot (390 meter) covered bridge crossing the Saint John River at Hartland, New Brunswick, Canada, is currently the longest covered bridge in the world. It is a Canadian National Historic Site. In 1900, New Brunswick had an estimated 400 covered bridges, and Quebec more than 1000, while Ontario had only had 5. As of 2006, there were 94 covered bridges still standing in Quebec and 65 in New Brunswick.

A much longer covered bridge (5,960 feet) between Columbia and Wrightsville, Pennsylvania once spanned the mile-wide Susquehanna River, making it the longest and most versatile covered bridge in the world during its existence. It featured railroad tracks, a towpath for canal boats crossing the river between two canals on either bank, and a carriage / wagon / pedestrian road. The popular tollbridge was burned June 28, 1863, by Union militia during the American Civil War to prevent its usage by the Confederate Army of Northern Virginia during the Gettysburg Campaign. A replacement wooden covered bridge was destroyed by a windstorm a few years later. It was rebuilt as an open-air steel bridge.

Covered bridges are generally considered old-fashioned, and appeal to tourists, but the purpose is twofold: (1) covered bridges appear similar to barns and it is easier to transport cattle across them without startling them, and (2) to build a structure for weather protection over the working part of the bridge. A bridge built entirely out of wood, without any protective coating, may last 10 to 15 years. Builders discovered that if the bridge's underpinnings were protected with a roof, the bridge could stand for 70, or even 80 years. The existing covered bridges have been renovated using concrete footings and steel trusses to hold additional weight and to replace the original support timbers.Some covered bridges, such as the one in Newton Falls, Ohio, also feature an integrated covered walkway.

Covered bridges in Europe

Famous covered bridges include the Rialto Bridge in Venice, Italy which is one of only three over the Canal Grande and a popular tourist attraction. The Bridges of Sighs in Venice, Cambridge and Oxford are also covered bridges.

Covered bridges in Asia

There are many covered bridges, called Wind and Rain Bridges in the Chinese province of Guizhou. These were traditionally built by the Dong minority people.

Taishun County, in the Zhejiang province, has more than 900 covered bridges, many of them hundreds of years old, as well as a covered bridge museum.[1]

Modern covered bridges

Modern covered bridges are usually for pedestrians, for example to walk from one part of an office building to another part, to cross railway tracks at a station, or in a shopping center on an elevated level, crossing a road. See also skyway.

Glass-walled covered bridges are rather common at American airports, and some of those bridges can be found at John F. Kennedy Airport in New York City.

Also, some highway bridges, such as the George Washington Bridge, have lower decks for additional capacity, and those decks, while generally open on the sides, can be enclosed with plastic from time to time during construction, thus rendering the lower decks as partially covered bridges.

Covered bridges in fiction

North American covered bridges received much recognition as a result of the success of the novel, The Bridges of Madison County written by Robert James Waller and made into a Hollywood motion picture starring Meryl Streep and Clint Eastwood.

The fictional rural town portrayed in the 1988 film Beetlejuice features a covered bridge. It provides the scene near the beginning of the film, in which the protagonists (played by Alec Baldwin and Geena Davis) crash their car through the wall of the bridge and plunge into the river below.

A covered bridge is also featured in the 1999 film Sleepy Hollow, in a suspense-filled scene depicting an encounter between main character Ichabod Crane (played by Johnny Depp) and the main villain, The Headless Horseman (played by Christopher Walken).

In the early 20th century, covered bridges were sometimes nicknamed "kissing bridges", as the cover allowed seclusion for couples to kiss each other.
