The project features a road-level tunnel with a wildlife overpass above it, allowing animals to cross safely while maintaining natural migration routes. The design reflects extensive ecological studies of wildlife behaviour in the surrounding forest areas. Officials said the project exemplifies close collaboration between the DoH, the Ministry of Natural Resources and Environment and conservation agencies.
