Mostly metal because it is strong and very stable
The most common materials used in bridge building are generally steel or concrete for larger bridges, and stone or wood for smaller bridges.
Steel is the most common, especially for suspension bridges. Concrete is used for lower bridges (and where little shifting will occur) because it is more resistant to the elements.
The most common types of straight bridges used in civil engineering projects are beam bridges, truss bridges, and arch bridges.
dark colored and rough textured
Most modern bridges are steel structure or framework. Limestone, dolomite and marble have been used in many historic buildings attesting to their durability.
Bridges have gone from simple wooden structures to strong iron and steel structures because of the advance in materials and technology. There are also more people working on building these bridges, so more complex structures can be built in a shorter time.
depends on the bridge type really. most are steel and concrete.
