Explanation:

The Grand Trunk Road is one of Asia's oldest and longest major roads — founded around 3rd century BCE by the Mauryan Empire of ancient India. The route spanning the Grand Trunk (GT) road existed during the reign of Chandragupta Maurya, 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. It does not passes through Rohtak.
