What was a technological achievement of the ancient Romans which improved transportation for them?

Answer 1

One achievement was the stone-paved roads. They had a military purpose. The speeded up and made easier the movement of troops and of supplies to soldiers at the front or in garrisons. Since Rome was at war so often, they were very important. They also made communications and the transport of goods for trade easier. The stone-paved roads were about 20% (80,500 kilometres, 50,313 miles) of the total network of Roman roads (400,000 kilometres, 250,000 miles). Roads, stone-paved or not, were essential to ensure adequate communication around the vast Roman Empire and to facilitate its huge trading network.

Another achievement was the construction of much bugger bridges which could cross much wider rivers and valleys and much deeper valleys. This was done with the use of arches and concrete, which the Romans developed to a high quality and used extensively. 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 archways and the 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 22metres (72 ft.) high. 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.).

Roman concrete also set underwater and was used to build the docks for much bigger ports, thus facilitating sea traffic.
