WORLD HISTORY

Detailed explanation-1: -The expected rate of construction was 1 1/2 yards (1.35m) per man per day (at 16ft-4.8m-most roads were just over 5 yards wide), and in at least one case 2 yards per man per day was achieved.

Detailed explanation-2: -The Apennine Mountains made it difficult for people to cross from one side of the peninsula to the other. These two groups of mountains helped to protect Rome from outside attacks. The seven hills protected Rome. The climate of Rome also helped the people of the city.

Detailed explanation-3: -Roman road system, outstanding transportation network of the ancient Mediterranean world, extending from Britain to the Tigris-Euphrates river system and from the Danube River to Spain and northern Africa. In all, the Romans built 50, 000 miles (80, 000 km) of hard-surfaced highway, primarily for military reasons.

Detailed explanation-4: -The road was constructed by filling the ditch. This was done by layering rock over other stones. Into the ditch was dumped large amounts of rubble, gravel and stone, whatever fill was available. Sometimes a layer of sand was put down, if it could be found.
