The arterial Nandanam signal has undergone a change from Wednesday with four-way traffic being closed to the public.
The signal which facilitates travel to T Nagar, Saidapet, Nungambakkam and Cenotaph Road has now reverted for a week to old rules that were in place during the construction of the Chennai Metro Rail (CMRL).
From 2012 to 2019, many changes were made on all approach roads to Nandanam junction due to metro rail construction. Vehicles from Venkatanarayana Road in T Nagar had to turn to South Boag Road and Pondy Bazaar before joining Anna Salai or take Burkit Road and Mooparappan Street before joining Anna Salai.
It was in July last year police reverted to the old arrangement, allowing four-way traffic at the junction, that existed before 2012. Almost after seven years, motorists could use the stretch again from all sides.
However, it failed to meet expectations causing massive jams for commuters during peak hours. In fact, the traffic near the Muthuramalinga Thevar statues spills on to the neighbouring colonies that motorists use as a short-cut to approach the Nandanam signal.
Meanwhile, the Greater Chennai Corporation is proposing to build grade separators at 15 congested junctions across the city at a cost of Rs 1,505 crore.
To decongest the ever-busy Nandanam junction, the civic body has proposed to build a 3-lane bi-directional flyover, connecting Venkatanarayana Road to Pasumpon Muthuramalinga Salai.
