                     What Are The Different Types 
Of Bridges?
Overview
Clearly, bridges are tremendously important for a nation. Bridges connect people, goods, and 
transports. In fact, they are crucial for human life and the economy. Therefore, it’s imperative 
to maintain them well. America is struggling with an infrastructure crisis for the last few 
years. However, things are getting better after the public-private partnership which involves 
an agreement between private transportation infrastructure companies and the US 
government. According to this agreement, a private transportation infrastructure agency 
invests in bridge infrastructure funds to help the government in repairing structurally 
deficient and functionally obsolete bridges. 
Let’s Dive Into Some Different Types Of Bridges:
Beam Bridge
Arch Bridge
Suspension Bridge
Beam Bridge
It is a very simple type of bridge that requires less 
investment. In order to build this bridge, you need a 
crossbeam covering the span, supported by an 
abutment at each end. Sadly, this type of bridge is 
less stable. However, adding supports like 
stanchions or piers can help you create a stable 
bridge. The 24-mile Lake Pontchartrain Causeway in 
Louisiana and the 3.2-mile Yolo Causeway near 
Sacramento are some examples of Beam Bridge. 
Arch Bridge
Well, previously Romans built several stone arch 
bridges! In fact, some of them are still present. The 
Pont-Saint-Martin bridge in Italy’s Aosta Valley is an 
example of an Arch Bridge. Clearly, arch bridges are 
based on the principle called compression. 
Suspension Bridge
It is the most recognizable type of bridge in the United 
States. As the name suggests, a suspension bridge 
involves pillars that are connected with suspension 
cables. The most iconic bridge named Golden Gate 
Bridge in San Francisco is the biggest example of a 
suspension bridge. More than 10 million people visit 
this bridge every year.
