Who built the Grand Trunk Road?
B. Sher Shah Suri
The route spanning the Grand Trunk (GT) road existed during the Maurya Empire, extending from the mouth of the Ganges to the north-western frontier of the Empire. The predecessor of the modern road was rebuilt by Sher Shah Suri, who renovated and extended the ancient Mauryan route in the 16th century. The road was considerably upgraded in the British period between 1833 and 1860.
