they are commonly used on highways and over rivers
you wear a tie. struts are found in bridges.
i dont know but its strong

Arch bridges are most used in Canada and the united states
on high ways where there are lots of supports
Concrete is composed of calcium carbonate and is commonly used in the construction of homes, sidewalks, bridges, and skyscrapers due to its strength and durability.
A strut is a rigid member that is primarily designed to resist axial compression. It is often used in structural applications to support loads and maintain the stability of a structure, such as in bridges, roofs, and frameworks. Struts can be found in various configurations and are essential for ensuring that structures can withstand external forces without buckling.
The term "building bridges" is commonly used to describe the process of establishing rapport with a group, be it local citizenry, allied forces, etc. In a literal sense it could also be used to describe the act of constructing a bridge!
Bridges
Most highway bridges and railroad bridges are simple beam bridges. In this type of construction, the road surface or deck is supported by a series of longitudinal beams made of concrete, steel or timber. These in turn rest on bearings, which reston piers or abutments.
some bridges are used to get to the other side of something
a triangle can distribute force down its sides to suppot weight, this helps it hold its shape. triangles are commonly used in trusses, a type of design commonly used in things like bridges.
