“The State Highways Department, Chennai Metro Rail and the police are working out plans to decongest the western suburbs of Chennai. The Metro Rail works are already progressing, while major arterial roads like Chennai-Tirupati Highway (more popularly known as Madras-Tirupati High Road), East Coast Road and Bengaluru highway will be widened and improved,” the official said. As the first step, State Highway expansion works would be taken up to clear bottlenecks in Ambattur, Avadi, Tiruninravur, Poonamallee, Kottivakkam, Neelankarai and Uthandi, facilitating the free flow of traffic, the senior official said. Official sources from the Highways Department, the major projects in the pipeline are upgrading East Coast Road from Chennai to Kanniyakumari to four-lane and making the road from Chennai to Kanniyakumari via Tiruchy and Madurai from four to six-lane, and widening the road from Chennai Port to Manali via Tiruvottiyur junction to decongest traffic.
