The very first bridges were made by nature itself‚ as simple as a log fallen across a stream or stones in the river. 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 branches together involved the use of long reeds or other harvested fibers

Truss Bridge is a one bridge style from a variety other bridges types. The truss bridge is made with a simple skeletal structure. This type of bridges is conceded as a one of the strongest simple design and cost less. Truss bridges were founded early in the history‚ and they were built from wood and iron at the first time‚ which was different than any other bridge that was made of stone. However‚ nowadays‚ truss bridges are made of steel. Truss bridges have many types include‚ the Pratt‚ the Warren

What is Trail Bridge? For any country to develop and prosper infrastructure is needed. And transport infrastructure is globally recognized as the must for development. Due to the physiological difficulties road transport is only the feasible and viable means of transportation in Nepal. Unfortunately‚ given the topography of Nepal‚ construction of road transport network in every part of the country is neither technically feasible nor economical. The only reliable means of transport for the hill and

dictionary‚ a bridge is a structure carrying a road‚ path‚ railroad‚ or canal across a river‚ ravine‚ road‚ railroad‚ or other obstacle. Bridges are essential for transportation. Whether it’s a canyon‚ or a body of water‚ bridges allow travel over those gaps from one part of land to the other. The world would be forever changed without bridges. The five main types of bridges are arch bridges‚ truss bridges‚ beam bridges‚ suspension‚ and cable-stayed bridges. Arch bridges are bridges that use arch

Suspension Of all the bridge types in use today‚ the suspension bridge allows for the longest spans. At first glance the suspension and cable-stayed bridges may look similar‚ but they are quite different. Though suspension bridges are leading long span technology today‚ they are in fact a very old form of bridge. Some primitive examples of suspension bridges use vines and ropes for cables. Typical Span Lengths 70m - 1‚000m+ World’s Longest Akashi Kaikyo Bridge‚ Japan Total Length 3‚911m
