Crib Bridge
Crib bridges were made from horizontally placed logs. The logs were laid first lengthwise, and then crosswise, in several layers. This consumed more trees than building trestle bridges, but they were easier to build without cranes or rams. Less common are crib bridges made from stone, such as the Bailey Island Bridge.

Bridge Across Nerepis River Westfield 1875
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Trestle Bridge
A trestle bridge is a bridge composed of a number of short spans supported by closely spaced frames. A trestle (sometimes tressel) is a rigid frame used as a support, historically a tripod used to support a stool or a pair of isosceles triangles joined at their apices by a plank or beam such as the support structure for a trestle table. Each supporting frame is a bent. A trestle differs from a viaduct in that viaducts have towers that support much longer spans and typically have a higher elevation. Timber and iron trestles (i.e. bridges) were extensively used in the 19th century, the former making up from 1 to 3 percent of the total length of the average railroad. In the 21st century, steel and sometimes concrete trestles are commonly used to bridge particularly deep valleys, while timber trestles remain common in certain areas. Many timber trestles were built in the 19th and early 20th centuries with the expectation that they would be temporary. Timber trestles were use ...

Bailey Island Bridge
The Bailey Island Bridge (also called the Cribstone Bridge) is a historic bridge in Harpswell, Maine, the town of Harpswell within Cumberland County, Maine, Cumberland County in the United States, state of Maine. History For many years, the residents of Bailey Island (Maine), Bailey Island, Maine, advocated that a bridge be built to connect their island with Orr's Island. The town of Harpswell, Maine, which encompasses both islands, turned down the request. However, when the Maine Legislature drafted a law allowing the state and counties to fund bridge construction, a plan emerged to build such a bridge. A contract was signed in 1926, with construction beginning on the Bailey Island Bridge in 1927 and finishing in 1928. The engineer for the project was Llewelyn N. Edwards, bridge engineer for the Maine State Highway Commission. Design Design of the bridge was complicated by the tides in the area known as Will's Gut. It was decided to build a cobwork bridge, using granite slabs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
