2. List of longest continuous truss bridge spans - Wikipedia

   en.wikipedia.org/wiki/List_of_longest_continuous...

   The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.

3. Cantilever bridge - Wikipedia

   en.wikipedia.org/wiki/Cantilever_bridge

   A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.

4. Cantilever - Wikipedia

   en.wikipedia.org/wiki/Cantilever

   Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. [1] Cantilever construction allows overhanging structures without additional support.

5. Simple suspension bridge - Wikipedia

   en.wikipedia.org/wiki/Simple_suspension_bridge

   The solution was found in 1691, by Gottfried Leibniz, Christiaan Huygens, and Johann Bernoulli who derived the equation in response to a challenge by Jakob Bernoulli. [4] Their solutions were published in the Acta Eruditorum for June 1691. [5] [6] A stressed ribbon bridge also has one or more catenary curves and a deck laid on the main cables ...

6. Truss bridge - Wikipedia

   en.wikipedia.org/wiki/Truss_bridge

   Unlike a continuous truss, a cantilever truss does not need to be connected rigidly, or indeed at all, at the center. [3]: 169–170 Many cantilever bridges, like the Quebec Bridge shown below, have two cantilever spans supporting a simple truss in the center. The bridge would remain standing if the simple truss section were removed.

7. Beam bridge - Wikipedia

   en.wikipedia.org/wiki/Beam_bridge

   The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid across a stream. Bridges designed for modern infrastructure will usually be constructed of steel or reinforced concrete, or a combination of both. The concrete elements may be reinforced or prestressed.
