How did Roman engineers improve construction?

When used in bridges and aqueducts, Roman builders improved on arches by flattening their shape to create what is known as a segmental arch and repeating it at various intervals to build stronger supports that could span enormous gaps.

The arch, together with columns, domes, and vaulted ceilings, became one of the defining features of the Roman architectural style.
