Additional information: Very little to expand upon, though it would be appreciated.
The elevated path is a feature/item that was introduced in Zoo Tycoon 2: Endangered Species. It is also a constantly meshed and colored user-made creation. It is a very useful tool that enables the player to make paths over areas you cannot usually build, such as conservation areas.
They are also useful in creating balconies over exhibits, allowing guests a better view of the animals inside.
