Several bridges and buildings are made out of limestone, a very common rock used in architecture. Other rocks used are sandstone, granite, and marble.
they used rocks and mud and put them into a half circle from one side to the other.
Rocks may help in building stable stone structures, such as fireplaces, bridges, and houses.

Arches National Park is comprised of over 2,000 sandstone arches. Basically, these are rocks that have been eaten away by erosion, leaving an "arch" left. The most famous of the arches is Delicate Arch.
Stone bridges were built to get over rivers etc, before iron or steel was used.
The most common materials used in bridge building are generally steel or concrete for larger bridges, and stone or wood for smaller bridges.
They are often built by military engineers to cross rivers where there are no bridges.
