The Incas built a large system of roads that went throughout their empire. The roads were usually paved with stone. Stone steps were often built into steep areas in the mountains. They also built bridges where the roads needed to cross rivers.he Inca were able to create sturdy stone buildings. Without the use of iron tools they were able to shape large stones and have them fit together without the use of mortar.
Unfortunately, records do not tell us how long it took to build Roman roads or how large the road gangs were that built them. The Appian WayââQueen of Roadsâ and forerunner of many other Roman roads on three continentsâwas begun in 312 B.C. as a road for use in the Samnite Wars. The 211 km. (132 mi.) to Capua must have been completed within about a decade. Ultimately, the Appian Way reached southward 576 km. (360 mi.) from Rome to Brundisium on the Adriatic Sea. The road system was gradually extended through the efforts of numerous Roman emperors. Agustus, Tiberius, Claudius, and Vespasian were among those who launched great road-building projects.
