Flyovers galore in Chennai but do we really need so many?

With the announcement of a slew of flyovers for the Chennai it is important to assess their impact and explore all alternatives.

It was just in January that a Government Order was issued for the construction of three new flyovers for the city at a cost of Rs. 335 crores. Now, Chennai’s new mayor Ms. Priya Rajan has signalled the administration’s intent to focus on a new batch of flyover projects as part of a roster of key civic solutions.

Flyovers are touted to be essential infrastructure to decongest traffic snarls, but whether the benefits are commensurate with the steep price tags is a matter of some debate.

Flyovers did not add much extra capacity

A 2016 piece in The Hindu states that Chennai has spent around Rs. 1,144 crores in erecting new flyovers. The sweeping project of the late 1990s saw the installation of nine new flyovers, resulting in the addition of an underwhelming 12.4 km of extra road capacity over the last decade – a period in which Chennai saw 60 lakh new vehicles descend upon its roads.

Curiously, the statistics may not be mere happenstance; senior retired officials have been reported to point out that the Society of Indian Automobile Manufacturers had a significant part to play in formulating the Traffic Action Plan of the 1990s.

The city roads are choked with traffic snarls that grow more severe every passing year. It is not unreasonable to wonder about the virtue of expensive flyovers that bring short-term benefits, ultimately enjoyed only by a small percentage of road users.

True cost of flyovers

In a quote to the media, Madhav Pai, the director of an organisation that works on sustainable transport solutions had this to say about the structures – “Elevated roads don’t work. Mumbai alone has spent close to Rs. 5,000 crore and there is still traffic. We’ve created an industry out of building flyovers. Cities have less and less money to spend on health and education because they’ve got locked into this high-cost investment pattern. This is not sustainable.”

The city doesn’t just bear an economic cost when it comes to flyovers, there are environmental and civic costs as well. Flyovers seem to set in motion a vicious cycle of congestion – by making it easier for vehicles to move through the roads, they arguably encourage new ownership, paving the way for a boom in new vehicles.

This is terrible for Chennai’s air pollution index, which, according to the Centre for Science and Environment, is reported to have the dubious record of being the second-worst vehicle polluter in the country after Delhi. Apart from having an impact on emission levels, new flyovers tend to rip the city as they come up, dislodging homes and public recreational centres.

Adding to traffic woes

Sometimes, they even make the traffic problem worse. K.P. Subramanian, former professor, Anna University is quoted in a news report thus – “In most cases, only particular intersections are upgraded, while the preceding ones or the ones that follow are not. Consequently, acute congestion is caused at landing points of ramps resulting in serpentine queues. The flyover near IIT is a classic example.”

Such infrastructure projects don’t always meet the approval of the public, either. A few years back, residents turned down a proposal by the Corporation to build a flyover at Mandaveli junction, feeling that the area would be served better by tackling encroachments and illegal parking.

Need to explore alternatives

It is rather baffling that flyovers are being prioritised at a time when growing environmental and climate concerns have made it clear that public transport must take precedence over private ones. A traffic management solution cannot exist in a silo that pays little heed to the city’s myriad eco-friendly initiatives such as electric buses, encouragement of Metro patronage and improvement of green cover.

Chennai needs a long-term fix that serves more than just the relatively small proportion of road users that are private vehicle owners. In fact, according to a piece authored by Kashmira Dubash of the ITDP (Institute for Transportation and Development Policy), the city of Ranchi put a stop to the construction of two flyovers in 2016, opting instead to make it easier for its citizens to cycle, walk and use public transport.

The article goes on to say that according to international standards, cities like Chennai require over 300km of mass rapid transit. Whether that is actualized through bus systems or the metro, it certainly seems to be a goal more deserving of the exchequer’s money than flyovers.

One hopes that the administration will subject such proposals to a fair evaluation by today’s standards, taking into account cost, impact and alternative solutions.

    Absolutely correct. The city needs more public transport in the form of more buses, preferably high end AC ones and more metro corridors. Politicians favour flyovers and approve them with alacrity as there is a lot of money to be made in the construction contracts. Hence dont expect any long term solutions. In my view, Chennai needs a combination of rail and road based metro systems, something akin to Singapore and Hong Kong. Nearer home we have Bus Metro in Ahmedabad which we can emulate at least in 4-5 arterial roads.

Inclusivity is pivotal to measures against heat, says urban planner Jaya Dhindaw

Urban researcher Jaya Dhindaw, highlights the need for reforms in building and labour practices to protect the most vulnerable against heat.

Across India, people have been suffering from extremely high temperatures, with some places experiencing multiple heat waves. The heat stress has been so acute that it has led to several deaths. During such extreme weather events, the India Meteorological Department (IMD) issues alerts. Advisories are also given out, asking people not to step out during the hottest part of the afternoon. But for many, staying indoors is not an option and as in any calamity, the worst affected are those that have the least protection — many of whom work in the informal sector. Others face equally harsh conditions indoors,…

Parandur Airport: What will this Rs 30,000-crore project mean for the environment?

More than 36,000 trees to be felled. Many water bodies to face destruction. What are the long-term ecological effects of Parandur Airport?

A ride on the dusty roads near the vast agricultural lands of Parandur and surrounding villages, and a stroll along the Ekanapuram Kadapan Thangal, one of the water bodies used for irrigation, makes one thing clear. The project site of the proposed Chennai Greenfield Airport, which encompasses more than 10 lakes and smaller water bodies, is rich in biodiversity. So, any construction activity here can have a long-lasting ecological impact. In the proposed Parandur project site, an area of 5,369 acres (2172.73 Hectares) has been earmarked for the development of the Chennai Greenfield Airport. Moreover, more than 36,000 trees will…
