River March, a city-based group working on nature and wildlife conservation, has written to the director of Sanjay Gandhi National Park (SGNP) drawing attention to the growing threat faced by wild animals along the Thane-Ghodbunder Road and the Western Express Highway. 

The group has called for the immediate installation and upkeep of wildlife crossing signages, and the creation of culverts, stating that these measures are crucial to ensure the safe movement of animals through this key wildlife corridor.
