Smithsonian National Zoo in Northwest Washington in Washington, District of Columbia — The American Northeast (Mid-Atlantic)
What's the O-Line?
In 1995, the Zoo debuted the O-Line, a series of towers and vine-like cables. It allows our orangutans to travel between the Great Ape House and Think Tank, if they choose to do so. Still innovative, the O-Line was the first "orangutan transport system" of its kind.
[Captions:]
Orangutans test a section of cables on the O-line before all towers are connected, 1994.
The best time to see our orangutans on the O-Line is on warm days from 11-11:30am.
Erected by Smithsonian Institution.
