This road was important for trade and for establishing communication throughout the persian empire

This road was called Royal Road.

Explanation:

The Persian Royal Road was an ancient road built by King Darius I in the 5th century. Dario built the road to provide rapid communication throughout his great empire from Susa to Sardis.

Archaeologists believe that the western part of the road was originally built by the kings of Assyria, as it proceeds through the heart of that ancient empire, by not following exactly the shortest and easiest way between the most important cities of the Achaemenid Empire. The eastern most parts of the road (now northern Iran) coincide with the largest known trade route, the Silk Road.

However, Dario I made the Royal Highway as it is known today by investing in the structure of the road and joining its parts completely, primarily as a fast mode of communication using the kingdom's pirradaziš, or messengers.
