Final answer:
Shi Huangdi, the first emperor of the Qin Dynasty, is credited with having a network of highways built to connect all parts of the empire, which included specific lanes for different purposes and symbolism.
Step-by-step explanation:
Shi Huangdi, the first emperor of the Qin Dynasty, had a network of highways built to connect all parts of the empire. Noteworthy is that these highways were part of a grander scheme of standardization that took place during his rule, from 220-210 BCE, which also included standardizing axle lengths for carts. This highway system facilitated the movement of troops, helped in consolidating the Qin ruler's control, and had a significant impact on the economy and society.
Roads were constructed with multiple lanes, designed with specific purposes - the central lane was solely reserved for the emperor. One of the roads, named "The Direct Road," symbolized the fairness and unity that Shi Huangdi sought to bring to the empire. These infrastructure projects were instrumental in shaping the logistical and administrative prowess of ancient China.
