For long, our city’s preferred solution to traffic congestion has been the construction of grade separators, better known as flyovers. These structures have merely shifted congestion points further ahead, but that reality seems to have escaped the attention of those involved in city planning. Nevertheless, flyovers are now an integral part of Chennai’s urban landscape. Besides creating bylanes beneath arterial roads, they have also generated large spaces underneath. Unfortunately, these areas often receive little maintenance and consequently become eyesores that detract from the appearance of the city.
Flyovers Urban Greening: A Promising Experiment
Faced with the challenge of maintaining public spaces beneath its flyovers, the Greater Chennai Corporation experimented with several solutions, one of the most visible being a much-publicised greening initiative. Saplings were placed in plastic receptacles attached to flyover pillars and supplied with water through an automated irrigation system. When functioning as intended, the project softened the harsh concrete landscape, added a touch of greenery to otherwise neglected spaces, and offered some respite from Chennai’s intense heat. For a time, the initiative appeared both visually attractive and environmentally beneficial, giving the impression of a successful urban intervention.
When Maintenance Becomes the Missing Link
Madras Musings, however, viewed the project with considerable scepticism and predicted that the greening effort would prove short-lived. Those concerns were soon vindicated. Not long after the transfer of the commissioner who had championed the scheme, the water supply was discontinued. The plants gradually withered, some of the receptacles were damaged or stolen, and others simply disappeared. Within a short period, the entire initiative had faded away without leaving a trace. What began as a thoughtful attempt to improve the cityscape ultimately became another reminder that even the best ideas cannot succeed without sustained maintenance and long-term institutional commitment.
Beautification Without Purpose
Another ambitious attempt to improve the appearance of spaces beneath flyovers came under the broad banner of beautification. The projects involved installing public art, benches, fountains and tiled flooring, all of which may have appeared attractive on paper. Yet they failed to address a fundamental question: who would actually choose to sit or spend time beneath a busy flyover? Predictably, such spaces were occupied largely by homeless people and other transient populations, meaning that the intended purpose of these interventions was seldom achieved. The projects demonstrated that making a space visually appealing does not necessarily make it functional or attractive to the public.
The Problem of Maintenance
The Corporation also struggled to maintain the installations and regulate their use. Public art deteriorated, fountains stopped functioning and tiled surfaces were damaged over time. As a result, much of the expenditure produced little lasting benefit. The experience demonstrates that beautification alone cannot transform spaces that face more fundamental challenges of usage, maintenance and accessibility. Before undertaking such projects, there needs to be a clear understanding of how these spaces will function on a daily basis and who they are intended to serve. Without this, beautification risks becoming an expensive exercise that delivers only temporary improvements to the urban environment.
Kathipara flyover’s Commercial Success
One of the few examples where the space beneath a flyover has been put to productive commercial use is Kathipara. An extensive food court has developed there and, because the area available is relatively large, it can accommodate both visitors and parking requirements. The location has demonstrated that spaces beneath flyovers can, under the right circumstances, be put to productive use. However, this success has also brought its own challenges. Food waste often accumulates after the outlets close for the day, creating sanitation concerns that require regular monitoring and effective management by the authorities.
A Practical Alternative: Paid Parking
There is now a growing view that similar commercial ventures could be encouraged beneath other flyovers across the city. In our view, however, this would be unwise. Unlike Kathipara, most flyovers do not have sufficient space to accommodate large numbers of visitors or meet their parking requirements. A more practical alternative would be to designate these spaces as paid parking bays. Such an arrangement could generate revenue for the Corporation while simultaneously helping address the city’s shortage of parking space. The idea is hardly new, as paid parking already exists beneath some flyovers. It remains difficult to understand why this relatively simple and practical solution cannot be expanded more widely across the city.
Addressing the Causes of Congestion
Those responsible for planning the city’s infrastructure would do well to remember that grade separators offer only limited benefits. While they may ease traffic flow at specific junctions, they do little to address the underlying causes of congestion. Long-term solutions require a broader approach to urban mobility, one that reduces the city’s dependence on private vehicles rather than continually adding more flyovers. This means strengthening public transport networks, improving last-mile connectivity and ensuring that pedestrian infrastructure is safe, accessible and convenient for everyday use.
Towards Sustainable Urban Mobility
Only by encouraging people to move away from private vehicles can Chennai hope to tackle congestion in a meaningful and sustainable manner. Better public transport, reliable feeder services and pedestrian-friendly pathways would allow many short journeys to be completed without a car or motorcycle. Such measures may lack the visibility and political appeal of a new flyover, but they are far more likely to deliver lasting benefits. In the long run, thoughtful urban planning will prove more effective than repeatedly constructing new structures and subsequently struggling to manage the spaces beneath them.
