GT Karnal Road

The Grand Trunk Road (formerly known as Uttarapath, Sarak-e-Azam, Shah Rah-e-Azam, Badshahi Sarak, and Long Walk) is one of Asia's oldest and longest major roads. For at least 2,500 years it has linked Central Asia to the Indian subcontinent. It runs roughly The Atlantic: "India's Grand Trunk Road"

Chandragupta Maurya, the founder of the ancient Indian Maurya Empire, built this highway along an ancient route called Uttarapatha in the 3rd century BCE, extending it from the mouth of the Ganges to the north-western frontier of the Empire.

The road coincides with current N1, Feni,(Chittagong to Dhaka), N4 & N405 (Dhaka to Sirajganj), N507 (Sirajganj to Natore) and N6 (Natore to Rajshai towards Purneain India; NH 12 ( Purnea to Bakkhali ), NH 27 ( Purnea to Patna), NH 19 (Kolkata to Agra), NH 44 (Agra to Jalandhar via New Delhi, Sonipat, Panipat, Ambala and Ludhiana) and NH 3 (Jalandhar to Attari, Amritsar in India towards Lahore in Pakistan) via Wagah; N-5 (Lahore, Gujranwala, Gujrat, Lalamusa, Jhelum, Rawalpindi, Peshawar and Khyber Pass towards Jalalabad in Afghanistan) in Pakistan and AH1 ( Torkham- Jalalabad to Kabul) to Gazani in Afghanistan.

Over the centuries, the road acted as one of the major trade routes in the region and facilitated both travel and postal communication. The Grand Trunk Road is still used for transportation in present-day Indian subcontinent, where parts of the road have been widened and included in the national highway system.

History

Ancient times

The Buddhist literature and Indian epics such as Mahabharata provide the existence of Grand Trunk road even before the Maurya Empire and was called Uttarapatha or the "Northern road". The road connected the eastern region of India with Central Asia and Ancient Greece.

Mauryan Empire

The precursor of the modern Grand Trunk road was built by the emperor Chandragupta Maurya and was based on the Persian Royal Road (more accurately, its eastern stretch, the Great Khurasan Road that ran from Media to Bactria). During the time of the Mauryan Empire in the 3rd century BCE, overland trade between India and several parts of Western Asia and Bactria world went through the cities of the north-west, primarily Takshashila and Purushapura modern-day Peshawar (in present-day in Pakistan). Takshashila was well connected by roads with other parts of the Mauryan Empire. The Mauryas had maintained this very ancient highway from Takshashila to Patliputra (present-day Patna in India). Chandragupta Maurya had a whole army of officials overseeing the maintenance of this road as told by the Greek diplomat Megasthenes who spent fifteen years at the Mauryan court. Constructed in eight stages, this road is said to have connected the cities of Purushapura, Takshashila, Hastinapura, Kanyakubja, Prayag, Patliputra and Tamralipta, a distance of around .

The route of Chandragupta was built over the ancient "Uttarapatha" or the Northern Road, which had been mentioned by Pāṇini. The emperor Ashoka had it recorded in his edict about having trees planted, wells built at every half kos and many "nimisdhayas", which is often translated as rest-houses along the route for the travelers. The emperor Kanishka is also known to have controlled the Uttarapatha.

Suri and Mughal Empires

Sher Shah Suri, the medieval ruler of the Sur Empire, took to repair The Chandragupta's Royal Road in the 16th century. The old route was further rerouted at Sonargaon and Rohtas and its breadth increased, a sarai was built, the number of kos minars and baolis increased. Gardens were also built alongside some sections of the highway. Those who stopped at the sarai were provided food for free. His son Islam Shah Suri constructed an additional sarai in-between every sarai originally built by Sher Shah Suri on the road toward Bengal. More sarais were built under the Mughals. Jahangir under his reign issued a decree that all sarais be built of burnt brick and stone. Broad-leaved trees were planted in the stretch between Lahore and Agra and he built bridges over all water bodies that were situated on the path of the highways. The route was referred to as "Sadak-e-Azam" by Suri, and "Badshahi Sadak" during Mughals.

British Empire

In the 1830s the East India Company started a program of metalled road construction, for both commercial and administrative purposes. The road, now named the Grand Trunk Road, from Calcutta, through Delhi, to Kabul, Afghanistan was rebuilt at a cost of £1000/mile.

The road is mentioned in a number of literary works including those of Foster and Rudyard Kipling. Kipling described the road as: "Look! Look again! and chumars, bankers and tinkers, barbers and bunnias, pilgrims – and potters – all the world going and coming. It is to me as a river from which I am withdrawn like a log after a flood. And truly the Grand Trunk Road is a wonderful spectacle. It runs straight, bearing without crowding India's traffic for fifteen hundred miles – such a river of life as nowhere else exists in the world."A description of the road by Kipling, found both in his letters and i
