Construction begins on eight 45-foot-tall towers at the National Zoological Park which connect the orangutans' living quarters at the Great Ape House with the Think Tank, and exhibit being constructed 500 feet away. The Orangutan Transit System, or O Line, is an innovative concept in exhibit desing that will allow the Zoo's Orangutans to "commute" between two physically separate facilities. Construction of the towers is completed in July 1994
