The roads will also have WiFi poles, CCTV cameras, info kiosks, and other amenities required to manage traffic better.
The chosen seven are Grand Southern Trunk (GST) Road, Grand Western Trunk (GWT) Road, Grand Northern Trunk (GNT) Road, Inner Ring Road, Velachery Bypass Road, Marmalong Bridge-Irumbuliyur Road, and Mount Poonamallee-Avadi Road.
A tender was floated on Monday to finalise a detailed project report (DPR).
A Rs 9 crore tender was floated on Monday for a consultant to prepare a detailed project report (DPR), said B Ganesan, project director of Tamil Nadu Road Sector Project II (TNRSP).
The consultant (highest bidder in the tender) will suggest ‘traffic calming’ measures such as road humps, rumble strips, and speed tables at appropriate places so that average speed of vehicles doesn’t exceed 50kmph, officials said.
The consultant will also suggest ways to ensure electric and telecom cables are laid underground properly and drains are properly aligned.
The highways department is responsible for managing about 270 km of roads in GCC limits. To reduce accidents and congestion, and make them non-motorised transport friendly, the government in 2021 issued orders to redesign these stretches, said Ganesan from TNRSP II.
Road safety expert M Radhakrishnan said that the reports prepared by consultants in the past for Chennai roads did not help in solving the problems. The changes they suggested were based on theoretical concepts and look good on paper, but the ground reality is completely different, he said.
“Consultants should come up with area-specific solutions instead of adopting a one-sizefits-all approach. The policy has to be based on the type of vehicles that frequent the stretch and should involve the local residents and experts,” said Radhakrishnan, founder of city-based NGO Thozhan.
