NHAI Builds Wildlife Overpass on Madurai Ring Road

09 Nov 2026 CW Team

The overpass crosses the four-lane NH 744A between Vadipatti and Thamaraipatti, along a stretch of about 30 km. According to an NHAI project director, the structure is approximately 40 m long and 20 m wide. Its location places the crossing within a forested section of the highway corridor, where movement between adjoining areas can be affected by road infrastructure.

The crossing is intended for gaur, spotted deer, wild boar and Indian hares. By carrying animals over the road rather than requiring them to cross the carriageway, the overpass provides a dedicated passage alongside the existing highway. The arrangement is designed to support movement between habitats without interrupting the flow of vehicles on NH 744A.

Wildlife crossings can take several forms, including underpasses, overpasses, ecoducts, green bridges, small-animal tunnels and wildlife viaducts. Roads can reduce available habitat, cause collisions, block access to resources and divide animal populations into smaller and more vulnerable groups. The performance of a crossing depends on factors such as its location, structure, target species, surrounding habitat and design, meaning that results can vary between sites.

The Madurai overpass therefore represents a site-specific measure incorporated into the ring-road project to address the effects of the highway on wildlife movement. Its dimensions and elevated design distinguish it from underground crossings, while its intended users include both large animals such as gaur and smaller species such as Indian hares. The structure is expected to function as a link between forest areas separated by the road.

The National Highways Authority of India (NHAI) has built a wildlife overpass in the forest area between Vagulamalai and Vannathikaradu in Tamil Nadu. The structure forms part of the Madurai ring-road project and is intended to provide animals with a safer route across the highway. It allows wildlife to move between forest areas while road traffic continues below. The overpass crosses the four-lane NH 744A between Vadipatti and Thamaraipatti, along a stretch of about 30 km.
