I have loads of ideas of what Bronx could do to improve circulation. For instance, instead of a monorail, the Zoo could replace it with a boardwalk made of recycled plastic. To further incentivize guests to come down, more charismatic species would be added such as Orangutans, Langurs, Pythons, Clouded Leopards, Fishing Cats, etc. The big question is what to do with the Elephants. I'd take them out of the former Monorail area. I'm not sure if the Zoo is still moving its service area to the former Rare Animal Range, but if it is, the Elephants could move into a brand new complex complete with a JungleWorld styled Elephant House. The outdoor yard would extend to/incorporate the old yard that currently houses White Rhinos, with the Rhinos possibly moving in with the Grevy's Zebras. New exhibits would also be added alongside the forested pathway, such as a hillside yard for Dholes near Himalayan Highlands, an extension of the former Polar Bear exhibit for Sloth Bears and Jackals, etc. Himalayan Highlands could also have some more species added, such as Takin near the Northern Ponds. In terms of what else could be done, the Monkey House would possibly turn into a Galapagos Island complex for Tortoises, Marine Iguanas, etc.
