Covered Bridges In Connecticut
Below is a list of covered bridges in Connecticut. , there were nine authentic covered bridges in the U.S. state of Connecticut; three of these are historic. A covered bridge is considered authentic not due to its age, but by its construction. An authentic bridge is constructed using trusses rather than other methods such as stringers, a popular choice for non-authentic covered bridges.

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 could 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. European and North American truss bridges Typically, covered bridges are structures with longitudinal timber-trusses which form the bridge's backbone. Some were built as railway bridges, using very heavy timbers and doubled up lattice work. In Canada and the U.S., numerous timber covered bridges were built in the late 1700s to the late 1800s, reminiscent of earlier designs in Germany and Switzerland. Th ...

West Cornwall Covered Bridge
The West Cornwall Covered Bridge (an earlier incarnation was known as the Hart Bridge) is a wooden covered lattice truss bridge carrying the Sharon-Goshen Turnpike over the Housatonic River in the town of Cornwall, Connecticut. Records indicate that a bridge may have been in place in this location as early as 1762. A previous bridge was destroyed in the flood of 1837 and a new bridge was constructed in 1841. This bridge would also be destroyed and the current bridge would be completed circa 1864. Utilizing the central pier from the previous incarnation, despite the Town lattice being able to withstand the weight and single span, the bridge has two spans. The later addition of queen trusses and supports gives the bridge an unusual appearance. Modernization of the bridge in 1968 and 1973 has continued to let the bridge handle traffic. It was added to the National Register of Historic Places in 1975. History Located at the north-south and east-west roadway section of the riversid ...

Arch
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

King Post
A king post (or king-post or kingpost) is a central vertical post used in architectural or bridge designs, working in tension to support a beam below from a truss apex above (whereas a crown post, though visually similar, supports items above from the beam below). In aircraft design a strut called a king post acts in compression, similarly to an architectural crown post. Usage in mechanical plant and marine engineering differs again, as noted below. Architecture A king post extends vertically from a crossbeam (the tie beam) to the apex of a triangular truss. The king post, itself in tension, connects the apex of the truss with its base, holding up the tie beam (also in tension) at the base of the truss. The post can be replaced with an iron rod called a king rod (or king bolt) and thus a king rod truss. The king post truss is also called a "Latin truss". In traditional timber framing, a crown post looks similar to a king post, but it is very different structurally: whereas th ...

Johnsonville Village, Connecticut
Johnsonville Village, once a thriving mill community, then a Victorian Era tourist attraction, was an abandoned ghost town in East Haddam, Connecticut, United States. On July 7, 2017, the property was acquired by the Iglesia ni Cristo (Church of Christ), an independent, nontrinitarian Christian denomination based in the Philippines. Mill community Harnessing power from the abundant water sources of the Moodus and Salmon rivers, the little hamlet became the center of twine production in Connecticut. The twine was primarily used for fishnets, and was sold on both coasts and the Great Lakes. In 1832, the Neptune Mill was constructed beside a dam just north of the Salmon River Cove. The Card Company, as it was then known also made stocking yarn and carpet warp. New cord wrapping machines filled these mills and twine was produced on a massive scale. Over the years, the Neptune Mill expanded until it reached its 100x100 ft dimensions. Three stories tall, it was a massive edifice ...

Pratt Truss
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

Avon, Connecticut
Avon ( ) is a town in the Farmington Valley region of Hartford County, Connecticut, United States. As of the 2020 census, the town had a population of 18,932. History Avon was settled in 1645 and was originally a part of neighboring Farmington, Connecticut, Farmington. In 1750, the parish of Northington was established in the northern part of Farmington, to support a Congregational church more accessible to the local population. Its first pastor was Ebenezer Booge, a graduate of Yale Divinity School who arrived in 1751. The Farmington Canal's opening in 1828 brought new business to the village, which sat where the canal intersected the Talcott Mountain Turnpike linking Hartford to Albany, New York. Hopes of industrial and commercial growth spurred Avon to incorporate. In 1830, the Connecticut General Assembly incorporated Northington as the town of Avon, after Avon (county), County Avon in England. Such expansion never came and, in the 1900s, the rural town became a suburban en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hartford County, Connecticut
Hartford County is a county located in the north central part of the U.S. state of Connecticut. According to the 2020 census, the population was 899,498, making it the second-most populous county in Connecticut. Hartford County contains the city of Hartford, the state capital of Connecticut and the county's most populous city, with 121,054 residents at the 2020 census.

Norwich, Connecticut
Norwich ( ) (also called "The Rose of New England") is a city in New London County, Connecticut, United States. The Yantic, Shetucket, and Quinebaug Rivers flow into the city and form its harbor, from which the Thames River flows south to Long Island Sound. The population was 40,125 at the 2020 United States Census. History The town of Norwich was founded on the site of what is now Norwichtown in 1659 by settlers from Saybrook Colony led by Major John Mason and James Fitch. They purchased the land "nine miles square" that became Norwich from Mohegan Sachem Uncas. One of the co-founders of Norwich was Thomas Leffingwell who rescued Uncas when surrounded by his Narragansett enemies, and whose son established the Leffingwell Inn. In 1668, a wharf was established at Yantic Cove. Settlement was primarily in the area around the Norwichtown Green. The 69 founding families soon divided up the land in the Norwichtown vicinity for farms and businesses. By 1694, the public landing bu ...

New London County, Connecticut
New London County is in the southeastern corner of Connecticut and comprises the Norwich-New London, Connecticut Metropolitan Statistical Area, which is also included in the Hartford-East Hartford, Connecticut Combined Statistical Area. There is no county government and no county seat, as is the case with all eight of Connecticut's counties; towns are responsible for all local government activities, including fire and rescue, snow removal, and schools. New London County contains reservations of four of the five state-recognized Indian tribes, although the Paugassett were historically located farther west. The population was 268,555 as of the 2020 census. History Southeastern New England was dominated by the Pequot people at the time of English colonization. They spoke the Mohegan-Pequot language and were one of the Algonquian-speaking tribes in the coastal areas. After years of conflict, the Colonists and their Indian allies defeated the Pequots in the Pequot War of 1637, endi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen Post
A queen post is a tension member in a truss that can span longer openings than a king post truss. A king post uses one central supporting post, whereas the queen post truss uses two. Even though it is a tension member, rather than a compression member, they are commonly still called a post. A queen post is often confused with a queen strut, one of two compression members in roof framing which do not form a truss in the engineering sense. The double punch truss appeared in Central Europe during the Renaissance. Architecture A queen-post bridge has two uprights, placed about one-third of the way from each end of the truss. They are connected across the top by a beam and use a diagonal brace between the outer edges. The central square between the two verticals is either unbraced (on shorter spans), or has one or two diagonal braces for rigidity. A single diagonal reaches between opposite corners; two diagonal braces may either reach from the bottom of each upright post to the cente ...
