One of the long forgotten devices created in the United States is that of the bridges. Yes, there certainly are bridges in the United States that are viewed as important landmarks, but more often than not, bridges are viewed as a thing of the past. This is dangerous, however, because it is important to constantly improve these bridges as time passes by.

People know very little about our environment like for instance the fact that there are different types of soils. Type A soils are considered cohesive soils with an unconfined compressive strength of 2 tons per square foot or more, which includes clay. Type B soils are cohesive soils with an unconfined compressive strength greater than 0.5 tons per square foot but less than 1.5 TSF which include gravel. Finally, Type C soils are cohesive soils with an unconfined compressive strength of 0.5 TSF or less.

Consider the fact that there are two basic types of shoring which are timber and aluminum hydraulic. In the year of 2015, the public sector put down just about $90 billion on highway construction. That budget is projected to grow to over $99.5 billion by the year of 2020. This is why it is important to know about driving over a military bridge because these bridges are essential to America. Here are some facts surrounding the construction of the military bridge.

The military bridge is not the only kind of bridge in the United States there are other bridges including the Truss bridge. This type of bridge design is popular and uses a diagonal mesh of posts above the bridge. The two most common designs are the king posts, which include two diagonal posts supported by single vertical post in the center, and queen posts which include two diagonal posts, two vertical posts and a horizontal post that connects the two vertical posts at the top.

Right now in the United States, there are over 600,000 bridges. Just about 2 hundred million trips are taken everyday cross bridges that are considered deficient. What’s worse is that these deficient bridges exist in the nation’s 102 largest metropolitan regions. This is why it is important to have facts on a military bridge to understand what is good and bad about the military bridge.

On average, one in every nine bridges across the nation is rated as structurally deficient. The average age of the military bridge in the United States is currently at 42 years. The Federal Highway Administration, or FHWA, handles a lot of the information surrounding public roads and structures. The FHWA estimates that in order to eliminate the nation’s bridge deficiency by 2020, we have to invest $20.5 billion annually because right now only $12.8 billion is being spent.

In Conclusion

There is no question you should seek out knowledge of temporary road construction and the constriction of the military bridge. It is essential for citizens of the United States to have a sense of what is going on in their country. So many people will drive on main roads every day not to mention highways and bridges across the country. These people should know that they are safe on these bridges and roads and that their lives are not in danger at all.
