The simple arch (barrel arch) ,which was invented by the Etruscans, has a great load bearing capacity. Therefore, it was used to build large buildings, gates of walls and bridges. By using this arch the Roman built longer and taller bridges which could cross much wider river and valleys and deeper valleys.
When bridges had to reach great heights, two or three tiers of arches could be built on top of each other to make the top of the bridge much higher. The greatest example of this technique is the Pont du Gard, a bridge with 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.)
The Romans also developed a more complex type of arch, the vaulted arch. This had an even greater load bearing capacity and was particularly useful to support large roofs and to build basements. The valued arch was crucial for supporting the inner structure of such a massive construction as the Colosseum. The vaulted arch has been widely used for building large churches through the many centuries from the Roman days and is still sometimes used today.
