The Tamil Nadu government is planning a Detailed Project Report for an elevated corridor between Tambaram and Chengalpattu to reduce traffic congestion. Minister Aadhav Arjuna also discussed plans for an eight-lane road between Chennai and Kanniyakumari to improve regional connectivity.
Why it matters
Infrastructure development is critical for economic growth and traffic management in rapidly urbanizing regions of Tamil Nadu.
Tamil Nadu Public Works Minister Aadhav Arjuna told the Assembly on Thursday (August 27, 2026) that the government would prepare a Detailed Project Report (DPR) to ease traffic congestion on roads linking Tiruvallur, Chengalpattu, and Mamallapuram to Chennai, and consider implementing the Tambaram–Chengalpattu elevated corridor.
Responding to former Chief Minister Edappadi K. Palaniswami, who sought to know whether the government would implement the Tambaram–Chengalpattu elevated corridor, conceived by the AIADMK government, Mr. Arjuna said the former Chief Minister was right in raising the issue. He said the government had already announced, during the demands for grants for the department, a plan to create an eight-lane road between Chennai and Kanniyakumari.
Mr. Palaniswami said the Centre was ready to implement the project, but it had been shelved by the DMK government.
Mr. Arjuna said the government had directed officials to prepare a DPR for the eight-lane road.
