To consolidate and strengthen his vast empire expanding from Indus valley (Pakistan) to Sonar valley of Bengal, Sher Shah Suri constructed a royal highway. This highway, which linked Kolkata to Peshawar, was renamed Grand Trunk (G.T.) Road during the British Raj. Presently, this road extends form Amritsar to Kolkata and is divided into two parts:
1. National Highway – 1 (NH – 1) – (Delhi to Amritsar).
2. National Highway – 2 (NH – 2) – (Delhi to Kolkata).
