Claycomb/Reynoldsdale Bridge had been recently reconstructed in 2006 and has a weight limit of 28 tons, this is not common for covered bridges. The bridge is located at the entrance of Old Bedford village, being a tourist attraction it has quite a lot of bus traffic that goes across the bridge, this would account for the heavy tonnage on the structure.
This bridge was originally built in 1880 at Reynoldsdale approximately fifteen miles north of its present location. The bridge was moved to its new location in 1975. This structure utilizes the Burr Truss and crosses Raystown Branch, Juniata River. The length of the bridge is 126 feet and the width is 13 ft. 10 in., it is open to all traffic and is in excellent condition. The location of the bridge is just west of State Route 220 at the entrance of Old Bedford Village, approximately 1.8 miles north of Bedford, Pennsylvania.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 lifespan 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 and keeping horses from shying away from water, are also sometimes called covered bridges.

History and development[edit]
Baumgardener's Covered Bridge, showing the truss protected by the covering
Early timber covered bridges consisted of horizontal beams laid on top of piles driven into the riverbed below. However, this construction method meant that the length between bridge spans was limited by the maximum length of each beam. The development of the timber truss circumvented that limitation and allowed bridges to span greater distances than those with beam-only structures or arch structures, whether of stone, masonry, or timber.[3]
Early European truss bridges used king post and queen post configurations. Some early German bridges included diagonal panel bracing in trusses with parallel top and bottom chords.[3] To solve the problem of deterioration of the wood upon exposure to weather, various forms of covering came to be employed.[4]
At least two covered bridges make the claim of being the first built in the United States. Town records for Swanzey, New Hampshire, indicate their Carleton Bridge was built in 1789, but this remains unverified.[5] Philadelphia, however, claims a bridge built in the early 1800s on 30th Street and over the Schuylkill River was the first, noting that investors wanted it covered to extend its life.[6] Beginning around 1820, new designs were developed, such as the Burr, Lattice, and Brown trusses.
In the mid-1800s, the development of cheaper wrought iron and cast iron led to metal rather than timber trusses, except in those areas of plentiful large timber.[3]

There are about 1600 covered bridges in the world.[7]
Asia[edit]
China: covered bridges are called l�ngqi�o (廊桥), or "wind and rain bridges" in Guizhou, traditionally built by the Dong. There are also covered bridges in Fujian.[8] Taishun County, in southern Zhejiang province near the border of Fujian, has more than 900 covered bridges, many of them hundreds of years old, as well as a covered bridge museum.[9][10] There are also a number in nearby Qingyuan County, as well as in Shouning County, in northern Fujian province. The Xijin Bridge in Zhejiang is one of the largest.
Europe[edit]

Switzerland has many timber covered bridges:[11] Bridge over the river Muota, Brunnen, near Lake Lucerne (picture), Berner Br�cke/Pont de Berne over the Saane/Sarine, near Fribourg, (picture), Kapellbr�cke.

North America[edit]
Canada[edit]
The 1,282-foot (391 m) Hartland Bridge in New Brunswick is the longest covered bridge in the world. In 1900 Quebec, New Brunswick, and Ontario had an estimated 1000, 400, and five covered bridges respectively. By the 1990s there were 98 in Quebec,[12] 62 in New Brunswick,[13] and one in Ontario, the West Montrose Covered Bridge.[14]
United States[edit]
According to Covered Bridges Today by Brenda Krekler, as many as 12,000 covered bridges once existed in the United States; that number dropped to under 1,500 by the 1950s.[15] The National Society for the Preservation of Covered Bridges was formed in 1950.[15]
The Federal Highway Administration (FHWA) encourages the preservation of covered bridges with its Covered Bridge Manual.[16]
Today, covered bridges exist in several states:
Alabama � see list of covered bridges in Alabama
California � eleven were reported in 2002,[17] including one at Knight's Ferry[18]

Delaware - Three bridges remain in New Castle county.
Georgia � see list of covered bridges in Georgia (U.S. state)
Illinois � five covered bridges remain in the state, most notably the Red Covered Bridge north of Princeton[19]

New Jersey � New Jersey had up to 35 covered bridges at its peak; many that were destroyed or damaged in various major floods are rebuilt as metal truss bridges.[26] Today, two covered bridges remain: Green Sergeant's Covered Bridge (19th century) and Scarborough Bridge (1959).[26]

Other bridges that are covered[edit]
Pont de Rohan
The term covered bridge is also use to describe any bridge-like structure that is covered. For example:
The Lovech Covered Bridge in Bulgaria is covered not for structural reasons, but to accommodate shops.
The Pont de Rohan in Landerneau, France and the The Pont des Marchands in Narbonne are two of 45 inhabited bridges in Europe.
A tubular bridge is a bridge built as a rigid box girder section within which the traffic is carried.[37] Examples include the Britannia Bridge and the Conwy Railway Bridge in the United Kingdom.
A skyway is a type of urban pedway consisting of an enclosed or covered footbridge between two buildings, designed to protect pedestrians from the weather. For example, the Bridge of Sighs in Cambridge, and Oxford's Bridge of Sighs and Logic Lane covered bridge.
A jet bridge is an enclosed, movable connector which extends from an airport terminal gate to an airplane, allowing passengers to board and disembark without having to go outside.[38]
Some stone arch bridges are covered to protect pedestrians or as a decoration as with the Italian Ponte Coperto and Rialto Bridge, and the Ch�a Cầu (the Japanese Bridge; picture) in Vietnam.
Covered bridges in fiction[edit]
Covered bridges are popular in folklore[39] and fiction.
North American covered bridges received much recognition as a result of the success of the 1992 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 Roseman Covered Bridge from 1883 in Iowa became famous when it was featured in both the novel and the film. A covered bridge is also prominently featured in the story "Never Bet the Devil Your Head" by Edgar Allan Poe, and covered bridges serve as plot points in the 1988 comedy films Beetlejuice and Funny Farm.
