The Origin

The Grand Southern Trunk Road, or GST Road as it’s commonly known, is more than just a road. It’s a symbol of India’s rich history and rapid development. This road has seen the passage of time, from the ancient era when it was a bustling trade route, to the British colonial period when it was developed into a crucial part of the Grand Trunk Roads, and finally to the post-independence era when the Indian government took over its enhancement.

Today, GST Road, which is part of National Highway 45 (NH45), is a lifeline for Chennai and Tamil Nadu. It starts from Kathipara Junction in St Thomas Mount, Chennai, and stretches all the way to Theni. It passes through key localities, connecting Chennai to other major towns and cities in the state. The National Highways Authority of India (NHAI) has been proactive in maintaining and upgrading the road, with recent initiatives including the proposal of a double-deck structure between the airport and Irumbuliyur and the rectification of accident-prone spots to enhance safety.

But GST Road is not just about the past; it’s also about the present and the future. With India’s economic liberalisation in the 1990s, the country experienced growth in numerous industries. Chennai, being one of the major cities, saw a surge in growth and development. Today, the city’s economy is driven by a variety of industries, including automobile, healthcare, manufacturing, and software services.

GST Road has played a significant role in this economic expansion. It remains a vital artery that connects some of the city’s most prominent neighbourhoods. The road, which is approximately 470 km long, connects Chennai and Trichy and is a vital commerce route connecting Chennai Airport to the city’s southern outskirts.

About 20 years ago, this stretch of road was just starting to grow. But due to its strategic location, several micro-markets have sprouted up along its length. Areas like Pallavaram, Chromepet, Tambaram, Perungalathur, Vandalur, Urapakkam, Guduvanchery, and Kattankolathur have become important commercial centres.

The journey of GST Road mirrors the evolution of India’s transportation infrastructure. From a simple trade route to a vital transportation artery, GST Road continues to play a pivotal role in the region’s economy and connectivity, shaping the lives of its residents and the future of the region. It’s a testament to India’s growth story and stands as a symbol of Chennai’s resilience and ambition.


GST Road is one of the primary connection networks in Chennai, providing crucial connectivity for the city and the surrounding regions. Its strategic location and infrastructure make it an essential transportation corridor for both residents and travelers. Here are the key aspects of connectivity on GST Road:

GST Road, fondly referred to as NH 45, is a vital lifeline that binds Chennai with several significant locations within Tamil Nadu and beyond. It serves as a crucial link between the city center and towns such as Tambaram, Chengalpattu, and Tindivanam, making it an indispensable route for daily commuters and goods transportation. Moreover, it opens up access to numerous commercial and industrial centers, bolstering trade, logistics, and goods movement in and out of Chennai.

GST Road’s strategic location near Chennai International Airport offers travelers effortless access to both domestic and international flights. This convenience extends to residents and visitors alike, ensuring smooth travel experiences. Furthermore, it’s not just the airport; major IT Parks are conveniently located along this road.

GST Road is seamlessly integrated with the city’s public transportation network, including buses and suburban trains. Tambaram, one of the busiest suburban railway stations, is situated along GST Road, offering connections to various parts of Chennai and other towns.

GST Road stands as a testament to modern infrastructure, designed to handle heavy traffic with ease. Multiple lanes, flyovers, underpasses, and service lanes all contribute to a smoother traffic flow and reduced congestion.

As a significant highway, GST Road provides access to several commercial and industrial hubs. This connectivity is crucial for the movement of goods to and from Chennai, supporting the city’s vibrant trade and logistics scene. Key employment hubs like Mahindra World City, Infosys, Capgemini, Wipro have their address on the GST Road.

GST Road’s importance is set to grow even further with several infrastructure projects in the pipeline. The Chennai Metro extension and planned improvements to the road network promise to enhance connectivity along GST Road in the coming years. The Chennai Metro Rail Limited (CMRL) has recommended that metro rail services be extended from Koyambedu to Avadi for an elevated stretch of 16.07 km with a tentative 15 stations. The state government is set to conduct studies to determine the feasibility of extending three corridors of the metro rail’s second phase. This includes a proposed extension to Sriperumbudur, passing through Thirumazhisai. The Phase II expansion has been planned for a length of 118.9 Km network with 128 nos. of Stations.

With an area of around 1,500 acres, the Arignar Anna Zoological park is India's largest Zoological Park. It is located 9 kilometres south of Tambaram on the GST route. The lush greenery makes it a nice spot to visit in a city that is typically known for its oppressive summer heat. The majority of animals are housed in an environment that is comparable to their natural surroundings. As a result, we don't see many caged animals here. Even the huge cats can roam freely in large regions separated from onlookers by moats.

Vedanthangal Bird Sanctuary is located 29 kilometres south of Chengalpattu toll plaza. Continue on GST road for 17 kilometres beyond the toll plaza, then turn right at Padalam intersection.

Birds from all over the world are believed to visit Vedanthangal.

Kolavai Lake is located in the Kanchipuram district. The lake is located on the southwest side of Chengalpattu town, bordering the Chennai suburbs. The lake has shrunk in size due to increased urbanisation, yet it has remained a perennial lake. Kolavai Lake is a great place for a picnic early in the morning to see the dawn.
