9 Common Reasons for Bridge Failures
Jan 06, 20176. Construction incidents. Some bridges never make it to completion. They fail during construction. A lesson learned from these incidents is that it's just as important for designers and engineers to plan all aspects of bridge construction step by step, analyzing the impact new phases will have on previous ones.

Connections in bridges
In ladder deck and multi-girder bridges, the structural connections are the splices in the longitudinal girders and the connections of the bracing or cross girders to the main girders. These connections can be made either using bolts or by welding and the choice between these two options has implications for both design and construction.. This article discusses the two

Aug 25, 2017Bridge Engineering The first bridges were made by nature — as simple as a log fallen across a stream. The first bridges made by humans were probably spans of wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement. Most of these early bridges could not support heavy weights or withstand strong currents.

18 Different Types of Bridges
Beam bridges are the oldest known form of bridge construction. Beams are placed in a horizontal fashion either on piers or some form of the abutment. In the early days of this construction, humans would use wooden piers to support the beams. Once these pieces were in place material would be used to create the walkway of the bridge.
