What is the least expensive type of bridge to build?
Beam Bridge
A beam or “girder” bridge is the simplest and most inexpensive kind of bridge. According to Craig Finley of Finley/McNary Engineering, “they’re basically the vanillas of the bridge world.”
What is the simplest type of bridge?
Beam bridges, also known as stringer bridges, are the simplest structural forms for bridge spans supported by an abutment or pier at each end. No moments are transferred throughout the support, hence their structural type is known as simply supported.
What type of bridge is the weakest?
The weight placed on a beam bridge is pressed directly downward, toward any underneath support, which makes the middle portion of the bridge the weakest.
What is the strongest type of bridge and why?
A truss bridge is the strongest kind of bridge. It combines materials in a simple and efficient way that reduces and spreads out loads over a large area. They flex less than other kinds of bridges and provide greater stability even in extreme weather or traffic.

What is the scariest bridge in the United States?
The William Preston Lane Jr. Memorial Bridge, known as the Chesapeake Bay Bridge, is widely considered the single scariest bridge in America — and it instills fear in the thousands of Baltimore, Maryland, and Washington, DC, drivers who use it every day.
Which is stronger arch or suspension bridge?
The arch bridge broke at 17.61 kilograms, the truss broke at 11.23 kilograms and the suspension, at 14.86 kilograms. In conclusion, the results of this test suggest that the experiment can be recreated on the computer and that the arch bridge design is strongest in the specific scenario of this experiment.
