Maduravoyal Junction, Road junction in Chennai, India

Maduravoyal Junction is a cloverleaf interchange where National Highway 4 meets the Chennai Bypass, featuring four elevated loops. These loops allow traffic to flow between different parts of the city without encountering intersections or traffic signals.

The junction was built in 2010 as part of the major Chennai Bypass expansion project. This development was essential for improving traffic flow and connecting outlying neighborhoods more directly to the city center.

The junction takes its name from Maduravoyal, the neighbourhood on Chennai's western edge where NH4 meets the Chennai Bypass. The cloverleaf's four loops are signed for specific movements: Tambaram to Koyambedu, Poonamallee to Tambaram, Puzhal to Poonamallee, and Koyambedu to Puzhal. A planned elevated expressway to Chennai Port is to begin here.

The four loops link Tambaram with Koyambedu, Poonamallee with Tambaram, Puzhal with Poonamallee, and Koyambedu with Puzhal, so pick the loop matching your origin and destination before entering. The junction sits west of Koyambedu Junction, at the crossing of NH4 and the Chennai Bypass.

The flyover's four loops are arranged so that traffic from Tambaram to Koyambedu, Poonamallee to Tambaram, Puzhal to Poonamallee and Koyambedu to Puzhal never meets a signal. The Chennai Port to Maduravoyal elevated corridor, a four-lane road on pillars, is planned to begin here.
