The police are likely to effect changes to traffic on Kamaraj Salai on Saturday.
Traffic movement will depend on the size of crowds on Marina beach.
In case of large crowds near Labour Statue, vehicles will be diverted at War Memorial towards Flag Staff Road, Anna Salai, GP Road, Tower clock and Dr. R.K. Salai.
Vehicles coming from Adyar will be diverted at Kannagi Statue towards Bharathi Salai, Bells Road and Wallajah Road.
The Bharathi Salai stretch will be made a one-way with entry from Kannagi Statue and no entry from Bells Road junction, the release said.
