The Romans were first to fully appreciate the advantages of the arch and the vault. The arch has a strong load-bearing capacity and provides stability. The the simple barrel arch was occasionally used in the ancient Middle East and Pergamon invented the vault (adjacent arches which are assembled side by side) which has an even greater load bearing capacity and whose structure is also suited to support large roofs. With the Romans arches and the vaults came to be used extensively for the first time. They became essential for the construction of large scale buildings, to support large roofs and to build basements. The Romans also used the arch to build gates, aqueducts,
With arches much longer bridges could be built. These bridges could cross much wider rivers and wider and deeper valleys. The Romans even managed to build a bridge across the lower Danube, which is a very wide river. If a deep valley had to be crossed, two or three piers of arches were built on top of each other to reach the desired height.
The Pont du Gard, a bridge for an aqueduct which supplied Nimes, in southern France is the greatest example of a multi- pier bridge. It has three tiers of recessed arches with the main piers in line one above the other. The first two tiers have very high and wide arches and a third tier has low and narrow arches. It was built to carry an aqueduct to Nimes in southern France. It reaches a height of 48.8 metres (160 feet). The lower tier is 142 metres (466 feet) long and has six aches with a height of 22metres (72 ft.). The second tier is 242 metres (794 ft.) long and has eleven arches 20 metres (66 ft.) high. The upper tier is 275 metre (902 ft.) long. It originally had 47 arches (only 35 have survived) 7 metres (23 ft.) high. The width of the first pier is 6 metres (20th.), that of the second pier is 4 metres (13 ft.) and that of the third pier is 3 metres (23 ft).
It is not known. The Romans must have built thousands of bridges because the empire was massive, it covered many mountain areas and it was crossed by many rivers. The bridges were built by the Romans, not the Roman Empire.
Cement was used by the Romans to build the colosseum. The Romans invented cement and the material they invented was also water proof which allowed for bridges and fountains to be built.
Usually concrete. Romans invented concrete.
bridges, they built bridges and other things
The Romans improved travelling conditions by building roads and bridges.
arch bridges
from what i remember from 6th grade they didn't.

The Romans made extensive use of the arch to build large buildings, bridges, and water aqueducts.
The ancient Romans used their engineering skills to build aqueducts, bridges, roads, domed structures, the hypocaust heating system and any other building projects they undertook.
Usually concrete. Romans invented concrete.
the Romans did create the bridges.

Roman engineering is not relevant today. The Romans did not have oil or electricity, which are the base of modern technology. The arch, which the Romans developed, was used to build bridges until the late 19th century.
