According to Greater Chennai Traffic Police, these changes will be implemented on a trial basis from April 20 to April 22, and commuters are advised to plan their routes accordingly.

The construction, overseen by the Highways Department, will affect key stretches and intersections in the area, prompting authorities to put alternate routes in place.

Diversion Plan

• Vehicles heading from Teynampet to Saidapet will be rerouted via Cenotaph Road and Turnbulls Junction. From there, they must take a right onto Pasumpon Muthuramalinga Thevar Road (also known as C.P. Ramaswamy Road), reach Nandanam Junction, and then take either left or right onto Anna Salai to continue towards their destination.
  
  
• Vehicles from Saidapet towards C.P. Ramaswamy Road will not be allowed. Instead, these vehicles must use Anna Salai and Cenotaph Road before reaching C.P. Ramaswamy Road.
  
  
• GKM Bridge (from Cenotaph Road) will be made one-way, and entry from Gandhi Mandapam Road to this stretch will be prohibited.
  
  
• Ratna Nagar Main Road will also become one-way from Cenotaph Road. Vehicles will not be allowed to enter from Anna Salai. However, entry is allowed from Anna Salai into Cenotaph 1st Street, but not from Cenotaph 1st Main Road.
  
  
• Vehicles coming from Kotturpuram towards Teynampet via Cenotaph Road will be restricted. Instead, they must use the GKM Bridge service road, go through Turnbulls Junction, reach C.P. Ramaswamy Road, then proceed to Nandanam Junction and continue on Anna Salai.
  
  

No-Parking Zones
To ensure smooth traffic flow, parking will be strictly prohibited on Anna Salai, Cenotaph Road, C.P. Ramaswamy Road, and other surrounding one-way roads.
