The Grand Trunk Road (GT Road) is one of the oldest and longest highways in Asia, stretching from Afghanistan across Pakistan, northern India, and into Bangladesh. Often called the “backbone of South Asia,” this legendary road has been a lifeline of trade, culture, and communication for more than two millennia.
Historically, it has connected important cities like Kabul, Lahore, Delhi, Varanasi, Kolkata, and Dhaka, serving as a route for armies, pilgrims, merchants, and emperors. Even today, parts of this ancient road are integral to India’s National Highway network and the Asian Highway system.
This article explores the Grand Trunk Road history, from its origins as Uttarpatha in the Mauryan period to its expansion under Sher Shah Suri, modernization by the British, and its role in independent India.
Sher Shah Suri built the Shahi (Royal) Road to strengthen his empire, stretching from the Indus Valley to Bengal’s Sonar Valley. During British rule, this road was renamed the Grand Trunk (GT) Road. Today, it connects Amritsar in the north to Kolkata in the south, remaining an important route.
The Grand Trunk Road history dates back over two millennia, making it one of the oldest and most significant roadways in South Asia. Originally built during the Mauryan Empire under Emperor Ashoka, the Grand Trunk Road was later reconstructed and expanded by Sher Shah Suri in the 16th century to connect Bengal in the east to Kabul in the west. Historically, “Uttarapath”, known by the name Sher Shah Suri Road or the Grand Trunk Road, has witnessed empires rise and fall, from the Mughals to the British. Understanding the gt road history helps us appreciate its enduring legacy in shaping regional connectivity and development.
The earliest name for the Grand Trunk Road was Uttarpatha, which literally means “the northern road.” This ancient route stretched across the Gangetic plains and beyond, serving as a major link between eastern and northwestern India. Traders, pilgrims, and travelers used it to transport goods and exchange ideas. The Uttarpatha became synonymous with cultural diffusion in ancient India.
Long before empires consolidated power, Uttarpatha facilitated trade in salt, spices, cotton, and horses. Merchants traveled between the Indus Valley and the Ganges plain, while scholars and monks spread philosophies, most notably Buddhism. This early road was not just about commerce but about shaping India’s intellectual and spiritual identity.
Throughout history, this road has been known by different names: Sadak-e-Azam, Badsbhahi Sarak, and Sadak-e-Sher Shah, highlighting its changing rulers and purposes. These names reflect its dynamic nature, from a simple trade route to a symbol of imperial power. Each era added layers of infrastructure and cultural relevance, shaping the GT Road history we study today.
The Mauryan dynasty recognized the importance of infrastructure in uniting vast territories. Chandragupta Maurya, the empire’s founder, emphasized roads as vital tools of administration and defense. Uttarpatha was reinforced to connect Pataliputra (modern Patna) with northwestern India, enhancing governance and ensuring military mobilization.
Ashoka, Chandragupta’s grandson, further extended the road network. Under his reign, when was the Grand Trunk Road constructed became a notable question for historians, as the Mauryan rulers systematically developed Uttarpatha into a structured pathway. Ashoka planted trees along the road, built rest houses, and ensured shade for travelers, initiating the practice of road-side amenities, which Sher Shah Suri later expanded.
The most remarkable phase in the Grand Trunk Road history came under Sher Shah Suri, the 16th-century Afghan ruler. Known for his administrative genius, Sher Shah ordered the reconstruction and extension of the ancient Uttarpatha. His version of the road stretched from Bengal in the east to the Indus River in the west, covering nearly 2,500 kilometers. This road became so iconic that many refer to it as the Sher Shah Suri Road.
Sher Shah Suri established sarais (inns) at regular intervals for travelers and merchants. These sarais also acted as postal stations, known as Dak Chowkis, where messages were quickly transmitted. By creating milestones, planting trees, and maintaining the road, he ensured safety and reliability. This effort made trade more efficient and facilitated faster communication across his empire.
Sher Shah Suri’s improvements elevated the road’s status to a political and commercial artery. The road enabled swift troop movements, efficient tax collection, and robust inter-provincial trade. In many ways, the Grand Trunk Road was built by Sher Shah Suri into the structured system that would later impress the Mughals and the British.
The British recognized the value of the Grand Trunk Road and undertook major renovations in the 18th and 19th centuries. They widened the road, added bridges, and reinforced its durability for military and administrative use. This modernization allowed the British to strengthen control over their Indian territories.
For the British, GT Road was essential for transporting raw materials like indigo, cotton, and opium to ports for export. It also facilitated the movement of British troops, ensuring dominance over local revolts. As industries grew, the road became a lifeline for internal markets.
The road’s strategic placement paralleled the expansion of India’s railway system. Together, they created a robust transport infrastructure that integrated rural markets with urban centers.
During the colonial period, the road earned its iconic name, Grand Trunk Road. The term “trunk” signified its primary status as the main artery, forming the backbone of the British communication network in India. This is when the GT Road full form became familiar to administrators and travelers alike.
Post-independence, the Grand Trunk Road was incorporated into India’s national highway system. Today, major stretches are covered by NH3, NH19, and NH44, which serve as critical links between states.
The GT Road is part of the Asian Highway Network, connecting India with neighboring countries and boosting regional trade.
Even today, GT Road plays a vital role in India’s economic development. It connects industrial zones, facilitates interstate commerce, and provides access to cultural centers. Its strategic importance lies in its role as a corridor for defense and international trade.
