Rangarajapuram flyover connects Kodambakkam and West Mambalam to T.Nagar. It was open only from T.Nagar 24 hours at the beginning and then better sense prevailed. Now between 8 am and 12 pm entry allowed only towards T Nagar side. It reduces the traffic volume on Kodambakkam flyover and Duraisamy subway. But inspite of sign boards mentioning the one way timings and barricade near Vivek and a traffic police motorists do come the wrong way. Why is that the authorities wake up only after some major accident happen? Do they really wake up or act so to blow over the public anger? It is very common to see the old violations coming back after sometime!
