Why Gandhinagar is a grid

A capital from scratch

After Gujarat was formed in 1960, the state needed a new capital. Ahmedabad served temporarily, but planners wanted a purpose-built city. In the mid-1960s, work began on a site 25–30 km north of Ahmedabad, on the west bank of the Sabarmati River. The city was named after Mahatma Gandhi, reflecting his legacy of simplicity and order. The design was entrusted to Indian planners H. K. Mewada and Prakash M. Apte. Both had worked on Chandigarh, India's most famous planned city. They brought that experience to Gandhinagar, creating a layout based on a clear grid system. The state government moved here from Ahmedabad in 1970. The grid was designed to be efficient and easy to navigate, with each sector having its own amenities.

The planning process began with a survey of the land and a study of other planned cities. Mewada and Apte visited Chandigarh and studied its sector system. They adapted the concept to suit Gujarat's climate and culture. The result was a city that is both orderly and green. The grid is not just a map; it is a way of life. Residents know their sector number and the main roads. The system has remained unchanged since the 1970s, a testament to its success. Today, Gandhinagar is often cited as one of India's best-planned cities, with a layout that prioritises open space and ease of movement.

The 30-sector grid

Gandhinagar is divided into 30 numbered sectors. Each sector is a self-contained neighbourhood, typically 800 by 1200 metres. Wide green belts separate the sectors, giving the city its reputation as one of India's greenest. The sectors are arranged in a rectangular grid, with main roads running north-south and east-west. The numbering starts from Sector 1 near the river and goes up to Sector 30 in the north and west. Not all sectors are fully developed; some remain as open land or are used for institutional purposes. The grid makes navigation straightforward: you can locate any sector by its number and its position relative to the main roads.

Each sector has its own character. Sector 1 houses the Sachivalaya, the state secretariat, and other government buildings. Sector 20 contains the Akshardham temple complex, a major landmark. Sector 13 is home to Mahatma Mandir, the convention centre, and Dandi Kutir, a museum on Gandhi's life. Sector 16 has the main market and bus station. Sector 11 is a residential sector with parks and schools. The variety of uses across the sectors means that the city is not just a collection of houses; it is a functioning capital with all the amenities needed for daily life. The green belts between sectors provide space for recreation and reduce the heat island effect.

• Sector 1 houses the Sachivalaya (secretariat) and government offices.

• Sector 13 is home to Mahatma Mandir and Dandi Kutir museum.
• Sector 16 has the main market and bus station area.
• Sector 11 is a residential sector with parks and schools.

Roads named after letters

The main north-south and east-west roads are named after letters of the Gujarati alphabet. These are single-letter names: Ch Road, Gh Road, J Road, K Road, Kh Road, G Road. The letters follow the order of the Gujarati script. This system is unique to Gandhinagar and makes finding your way simple once you know the sequence. Cross roads are numbered, such as Ch-0, Ch-1, Ch-2, and so on. The number indicates the distance from a reference point. For example, Ch-0 is the starting point of Ch Road near the river. This combination of lettered main roads and numbered cross roads creates a logical address system. You can tell where a location is by the road name and number.

The road naming system was a deliberate choice by the planners. They wanted to use Gujarati to reflect the state's identity. The letters are easy to remember and provide a clear hierarchy. Main roads are wide, with multiple lanes and service roads. The cross roads are narrower, leading into the sectors. The system also helps with emergency services: an ambulance or fire engine can quickly locate a sector by the road name and number. For visitors, the system takes a little getting used to, but once you understand the pattern, it becomes intuitive. The roads are well-maintained and lined with trees, adding to the city's green character.

Influence of Chandigarh

Gandhinagar's planners drew directly on the experience of Chandigarh, designed by Le Corbusier. Like Chandigarh, Gandhinagar uses a grid of sectors, each with its own amenities. The green belts between sectors are a feature borrowed from Chandigarh's design. However, Gandhinagar adapted the concept to a smaller scale and a different climate. The road naming system is a local innovation. Chandigarh uses a system of sectors and roads named after numbers and letters of the English alphabet. Gandhinagar uses Gujarati letters, reflecting the state's language and culture. The planners also incorporated wide roads and roundabouts, which are common in planned cities but rare in older Indian towns.

Both cities have a central axis with government buildings. In Chandigarh, the Capitol Complex houses the legislature and high court. In Gandhinagar, the Sachivalaya is the main government building, located in Sector 1. The green belts in Gandhinagar are wider, giving a more open feel. The road width is uniform across the grid, unlike Chandigarh where some roads are wider than others. The sectors in Gandhinagar are smaller, making them more walkable. The planners also paid attention to the orientation of buildings to maximise shade and ventilation. The result is a city that feels spacious and airy, even in the hot summer months.

• Gandhinagar's sectors are smaller than Chandigarh's.
• Green belts in Gandhinagar are wider, giving a more open feel.
• The road width in Gandhinagar is uniform across the grid.

Sector 11 and Ch Road

Sector 11 lies in the central part of the grid, near the intersection of Ch Road and the east-west G Road. It is a residential sector with wide tree-lined streets and several parks. The sector is typical of Gandhinagar's design: low-rise buildings, plenty of open space, and easy access to main roads. Ch Road runs along its eastern edge. Ch Road is one of the main north-south arteries. It starts near the Sabarmati River at Sector 1 and runs north through Sectors 2, 3, 4, and so on, up to Sector 30. The road is named after the Gujarati letter 'Ch' (ચ). Along Ch Road, you will find cross roads numbered Ch-0, Ch-1, and so on, which lead into the sectors. This makes Sector 11 easy to locate and navigate.

Sector 11 is a good example of the grid's efficiency. The sector has its own market, a few parks, and a school. The wide roads allow for easy parking and movement. The green belt on the western side of the sector provides a buffer from the next sector. From Sector 11, you can walk to the Indroda Nature Park, which is just across the road. The sector is also close to the Mahatma Mandir complex in Sector 13. The grid ensures that all these amenities are within a short distance. For residents, the sector offers a quiet, leafy environment while still being connected to the rest of the city.

Living in the grid

The grid system makes daily life convenient. Each sector has its own market, school, and health centre, so residents rarely need to travel far. The wide roads and green belts reduce traffic congestion and provide space for walking and cycling. The city's low population density means open spaces are abundant, and the grid ensures that no sector is far from a main road. However, the grid also has limitations. The numbered sectors can feel repetitive, and the lack of mixed-use development means you often need to drive to reach shops or services outside your sector. The city's planned nature means there are few narrow lanes or unexpected corners, which some visitors find monotonous. But for those who value order and greenery, the grid is a strength.

The grid also affects social life. Because each sector is self-contained, residents tend to stay within their own sector for daily errands. This creates a sense of community, but it can also lead to isolation between sectors. The wide roads and green belts act as barriers, making it less likely for people from different sectors to meet casually. However, the main roads and public spaces, such as the parks and the riverfront, bring people together. The grid is not just a physical layout; it shapes how people interact with the city and with each other. For a visitor, the grid makes Gandhinagar easy to explore, but it also means you need to plan your route carefully.
