An arch bridge is stronger than a beam bridge, simply because the beam has a weak point in the center where there is no vertical support while arches press the weight outward toward the support. Arch bridges, meanwhile, have been used to cover very long distances, with up to 800 feet for a single arch.

List of Strengths of an Arch Bridge

• It provides a higher level of resistance.
• It design is good in terms of pressure.
• It can be built from virtually anything.
• It is structurally sound.
• It comes with no distortion.
• It becomes stronger as it works.
• It offers economic advantages.

List of the Disadvantages of Arch Bridges

• Arch bridges provide a finite span with each set of abutments.
• It is a design option which requires an experienced hand.
• The arch must be perfect for the bridge design to be adequate.
• Arch bridges can sometimes have too much flexibility.

A truss bridge is the strongest kind of bridge. They flex less than other kinds of bridges and provide greater stability even in extreme weather or traffic.

Not only do they incorporate the strength of a strong arch shape, but they’re also made up of many triangles. Triangles are the strongest shape because they have fixed angles and don’t distort very easily.

The shape of a structure affects how strong it is. Rectangles, arches, and triangles are the most common shapes used to build big structures. The weight pushes down on the rectangle and causes the top side to bend. The weight pushes this arch into a stable, tightly squeezed shape.
