pillars, which makes this bridge the longest cantilever bridge in the world. While the bridge was under construction, the suspended span collapsed on two occasions (in 1907 and 1916), killing many workers. Trains began using the bridge in 1917 while automobiles were only allowed on it in 1929. Worlds Longest Truss Bridge Pont de Quebec
As owners replace their bridge infrastructure, the question of Life Service and Life Cycle Costs routinely comes up between concrete and steel bridge options. This is especially true for typical and short span bridge replacement projects. The bridge industry does not have a good answer: Both steel and concrete bridge advocates claim an advantage.

target design service life of the bridge system. The end of service life for a bridge element, com-ponent, or subsystem does not necessarily signify the end of bridge system service life as long as the bridge element, component, or subsystem could be replaced or resume its function with retrofit.
These temporary bridges were always short and therefore relatively low and vulnerable to floods. When I came across some 24 ft long scaffold trusses I knew exactly what to do with them. The plan was to create a bridge that can safely support an ATV (we call them four wheelers) and be used for foot traffic.
Trusses have been used in a similar way to beams in composite decks (Oresund Approach Spans), as arches (Sydney Harbour Bridge), as cantilevers (Forth Rail Bridge) or as stiffening girders to suspension bridges (Forth Road Bridge). Today, the truss girder form of construction usually proves expensive to fabricate because of the large amount of , customized steel structure of skate ramps
The Howe Truss was designed by William Howe in 1840. It used mostly wood in construction and was suitable for longer spans than the Pratt truss. Therefore, it became very popular and was considered one of the best designs for railroad bridges back in the day. Many Howe truss bridges exist in the North West United States, where wood is plentiful.See more on garrettsbridges, customized steel structure of skate ramps

Truss bridge is a type of bridge whose main element is a truss which is a structure of connected elements that form triangular units. Truss is used because it is a very rigid structure and it transfers the load from a single point to a much wider area. Truss bridges appeared very early in the history of modern bridges and are economic to construct because they use materials efficiently.See more on historyofbridges, customized steel structure of skate ramps

Alfred Neville of France patented the Warren Truss Bridge and also built the first bridge in the mid 19th century. It began its use in Britain and Europe in the 19th century and is now used all over the world. It was extensively used in the construction of railway bridges which was the main form of transportation for long distances in that period.
Truss is a formation produced by triangular components, in accordance with the truss bridge drawings, and coupled at joints known as nodes. The triangular units forming the truss are slim and straight in form. The truss bridges consist of a grouping of triangles that are manufactured from straight and steel bars, according to the truss bridge designs. The solid arms of the triangle are extended from the pier sides. The diagonal steel tubes proSee more on brighthubengineering, customized steel structure of skate ramps
