The National Highways Authority of India (NHAI) has built a dedicated wildlife overpass on the Madurai Ring Road in Tamil Nadu, introducing a road infrastructure measure designed to protect animals and maintain connectivity between forest habitats.
Located between Vagulamalai and Vannathikaradu, the structure crosses the four-lane NH-744A highway along the Vadipatti–Thamaraipatti stretch. It is approximately 40 metres long and 20 metres wide, according to NHAI officials.
The overpass is designed to allow animals to cross above highway traffic, reducing the risk of collisions and helping preserve movement between adjoining forest areas.
Designed for Multiple Wildlife Species
The crossing is intended for gaur, spotted deer, wild boar and Indian hares. The elevated structure provides a dedicated passage for wildlife while vehicles continue to use the highway below.
Road infrastructure can fragment natural habitats, restrict animal movement and increase the risk of road accidents involving wildlife. Dedicated crossings are designed to reduce these impacts by connecting habitats separated by highways.
Part of the ₹1,024-Crore Madurai Ring Road Project
The wildlife overpass forms part of the 29.96-km Vadipatti–Thamaraipatti section of NH-744A, developed at an estimated cost of ₹1,024.66 crore.
The four-lane corridor connects NH-44 and NH-38, helping vehicles bypass Madurai city. The project includes four major bridges, 29 minor bridges, two flyovers and several vehicular and pedestrian underpasses.
The highway is also equipped with an Advanced Traffic Management System featuring AI-enabled cameras and variable message signs for traffic monitoring and real-time alerts.
According to NHAI, the corridor is expected to reduce travel time on the stretch from around 45 minutes to 20 minutes and improve connectivity to industrial and tourism destinations in the region.
The wildlife overpass is a key environmental feature of the project, combining highway connectivity with measures to support the movement of animals across the forest corridor.
