A History of Transit in Portland

The history of TriMet is steeped in Oregon’s fabled pioneering spirit. Founded 45 years ago from the ashes of the bankrupt Rose City Transit, TriMet has been profoundly influential in shaping the growth and character of the Portland region. Through innovations in policy development, system design and technological advancement, the agency continues to set benchmarks for the transit industry at home and abroad.
