Covered bridge

A covered bridge is a timber-truss bridge with a roof 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 have a lifespan of only 10 to 15 years because of the effects of rain, snow and sun.

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

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.

Indiana

Indiana ⁱ/ɪndiˈænə/ is a U.S. state located in the midwestern and Great Lakes regions of North America. Indiana is the 38th largest by area and the 16th most populous of the 50 United States. Its capital and largest city is Indianapolis. Indiana was admitted to the United States as the 19th U.S. state on December 11, 1816.

Before becoming a territory, varying cultures of indigenous peoples and historic Native Americans inhabited Indiana for thousands of years. Since its founding as a territory, settlement patterns in Indiana have reflected regional cultural segmentation present in the Eastern United States; the state's northernmost tier was settled primarily by people from New England and New York, Central Indiana by migrants from the Mid-Atlantic states and from adjacent Ohio, and Southern Indiana by settlers from the Southern states, particularly Kentucky and Tennessee.

Indiana has a diverse economy with a gross state product of $298 billion in 2012. Indiana has several metropolitan areas with populations greater than 100,000 and a number of smaller industrial cities and towns. Indiana is home to several major sports teams and athletic events including the NFL's Indianapolis Colts, the NASL's Indy Eleven, the NBA's Indiana Pacers, the WNBA's Indiana Fever, the Indianapolis 500, and Brickyard 400 motorsports races.

Golf

Golf is a club and ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible.

Golf is one of the few ball games that do not require a standardized playing area. The game is played on a course with an arranged progression of either nine or 18 holes. Each hole on the course must contain a tee box to start from, and a putting green containing the actual cup. There are other standard forms of terrain in between, such as the fairway, rough, and hazards, but each hole on a course is unique in its specific layout and arrangement.

Golf is played for the lowest number of strokes by an individual, known as stroke play, or the lowest score on the most individual holes in a complete round by an individual or team, known as match play. Stroke play is the most commonly seen format at all levels.

Origin

Bridge

A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that each serve a particular purpose and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it.

Etymology

The Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning. The word can be traced directly back to Proto-Indo-European *bʰrēw-. The word for the card game of the same name has a different origin.

History

The first bridges made by humans were probably spans of cut wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement. Some early Americans used trees or bamboo poles to cross small caverns or wells to get from one place to another. A common form of lashing sticks, logs, and deciduous branches together involved the use of long reeds or other harvested fibers woven together to form a connective rope capable of binding and holding together the materials used in early bridges.
