The purpose of a bridge is that less effort and time are used to help crossing obstacles such as rivers, valleys or lakes. Bridges are made of materials such as stone, wood, steel and concrete and the load acting on it can be mostly vehicles or pedestrians.
History
Bridges began to be used in ancient times by primitive people using natural resources such logs and slabs of rock. Then the Roman empires became the first great bridge builders and they used rocks and concrete to build Arch Bridges. Until the nineteenth century, Europeans built modern bridges using steel and iron.

In the image above, the tracks seem to span into the distance, with no end in sight. There are numerous men working on and alongside the bridge, some even on a makeshift barge. The Central Pacific Railroad Company is nearing completion of this bridge in the picture, with all the columns and rails already in place.…

    A lot of construction equipment and material were present on the south side of the bridge, which also was the weaker side of the bridge. It should have been noticed that this construction material and equipment were having an impact on the load bearing capacity of the structure. Eventually, this also added reason to the structure's failure. Although the cracks were noticed, experts did mention that it is most probably no coincidence that the failure of the structure took place while there were additional loads of the construction equipment and materials. The ongoing construction work consisted of resurfacing and maintenance of guardrails, lights and other repairs.…

    Part A: Here in Tennessee we are in a valley with lots of lakes and water falls between the mountains. The water falls have swinging bridges going across them and not everyone will walk across because of the fear of it breaking or swinging too much. So my idea is to have the children build a regular bridge with a roof that does not swing and sheds shade to those in wheel chairs can enjoy the water falls and bridge as well. In this activity we will use Lincoln logs to build a two layer bridge that stretches across with a covered top. First we will sort the logs by size.…

    In order to come up with a solution to prevent bridge failure, we must understand what cause bridges to collapse in the first place. There is a bundle of issues that cause bridges to collapse, but the main reason is when a mix of factors take place simultaneously. If these factors took place one at a time then maybe we can pinpoint the problem before it leads to failure. Some of these issues might be due to overload, or maybe a natural disaster, and the bridge wasn’t stable enough to withstand it. One example of a bridge that failed is the I-5 Skagit River Bridge.…
