Streetcars, buses and other forms of public transit began operating in the Portland area in the 1870s. Nearly a century later, in 1969, the Oregon legislature consolidated local transit through their creation of the Tri-County Metropolitan Transportation District of Oregon--now called TriMet. This collection includes both practical maps designed for the traveling public, and planning maps used by public agencies as they considered the development of new infrastructure and services.
