Bridge - Bridge - Truss:A single-span truss bridge is like a simply supported beam because it carries vertical loads by bending. Bending leads to compression in the top chords (or horizontal members), tension in the bottom chords, and either tension or compression in the vertical and diagonal members, depending on their orientation. Trusses are popular because they use a relatively small
Bridges - Steel ConstructionS355 steel is predominantly used in highway bridge applications, as it is readily available, and generally gives the optimum balance between stiffness and strength. S275 steel is often used on railway bridges, where stiffness rather than strength governs the design, or where fatigue is the critical design case. S420 and S460 steels can offer

STRUCTURE DESIGN AND CONSTRUCTION ON THE VAIL Austin B. Milhollinif, International Engineering Company, San Francisco Cade L. Benson, International Engineering Company, Denver Bridge construction on the 22.5-km (14-mile) long segment of 1-70 through Vail Pass in Colorado presented unique problems to both designers and constructors because of the extraordinary care taken
Steel Bridges - an overview ScienceDirect TopicsWeiwei Lin, Teruhiko Yoda, in Bridge Engineering, 2017. 7.1 Introduction. Steel bridges are widely used around the world in different structural forms with different span length, such as highway bridges, railway bridges, and footbridges. The main advantages of structural steel over other construction materials are its strength, ductility, easy fabrication, and rapid construction.
This is the simplest type steel bridge having RSJ as the girder and steel trough plate filled with concrete or reinforced concrete slab as the bridge deck as shown in Fig. 14.1.

WOODEN AND METAL TRUSS BRIDGES - TN.govMarion Memorial Bridge:This historic postcard view shows the Marion Memorial Bridge (#129, 58- SR002-21.19), a high steel truss bridge that spans the Tennessee River near Jasper in Marion County. Erected by the state in the late 1920s, the bridge replaced a ferry.
bridge History, Design, Types, Parts, & Facts BritannicaBridge, structure that spans horizontally between supports, whose function is to carry vertical loads. Generally speaking, bridges can be divided into two categories:standard overpass bridges or unique-design bridges over rivers, chasms, or estuaries. Learn more about the
